  1. Hello Nesiya, This is not U. parthenopipes but a related new species that is currently know as Utricularia sp. 'Chapada Diamantina'. However it will have a proper name in a few weeks ;). Just be patient! The flowers of this species can be white or pale mauve. Yours is a bit unusual in having a double-lobed upper lip. All the best, Andreas
  2. Dear Monique, Fantastic photgraphs! I can give you the IDs of all of your plant you have seen ;) First of all the most spectacular: the white flowered plant from Red Hill: This is the TYPE form of Drosera zeyheri, the plants that Salter described from Red Hill, Simmonstown! Did you see the plants this year? Congratulations for this finding!! Fernando, Robert and I were looking for that exact plant at Red Hill for hours and hours! But the only thing we found in 2006 was odd D. trinervia. We even re-visited that location a few days later with the famous South African CP explorer Eric Green, who knows most Drosera locations in South Africa. He has seen this plant in the wild years ago, too, and took us back to the exact place he has found it. We searched for hours, once again, even at night with torches! Nothing! We thought that this plant had become extinct, as its known locations are situtated within some shanty villages now. Thus I'm really happy that you found that plant again! Dani, D. zehyeri can bear up to about 3 leaves along its stem, however there are occassionally no leaves on the stem at all! Nevertheless, it's easy to distinguish from the related D. pauciflora and D. cistiflora by its petals which have a truncate apex, by the much smaller flower size and the different braching mode of the stigmatic tips. The red rosetted Drosera you found at Tablemountain on the dripping wall is D. aliciae. I have been at the same place in 2006. Fantastic site, isn't it? ;) The other Drosera you found near the mountain top you have already correctly identified as D. trinervia. The accompaying Dias is Disa tenuifolia (old names: Disa patens and Disa lutea). Hope this helps, Andreas PS: The green glandular plant growing with D. aliciae on that cliff is a member of Asteraceae. For sure no Drosera ;) PPS: Dani, Marek, it is easy to distinguish D. zeyheri from D. pauciflora by vegetative part only: leaves of D. pauciflora are broadly cuneate, have a "blunt" leaf apex and long, enlarged non sticky glands that emerge from a very broad base (what Siggi calls "snap-tentacles"). In D. zeyheri, the leaves are oblong, have an acute apex with few or no snap-tentacles.
  3. Dear François, Congrats, you are one of the few CPers to grow the rare D. alba! ;) (the real thing!) Andreas
  4. Hello, Martin, it seems like this is the topic of mistakes and little faults, haha ;). Here's mine: Kamil, you can now remove the gun from your smiley! ;) Maybe you should put one on mine: unsure.gif I first had some doubts about those plants of U. arnhemica in cultivation, mainly because of small flower size, different indumentum of the palate and trap size. No that I have had the time to study some more material of U. arnhemica in detail (thanks for your herbarium specimens, too, Kamil! ;)), and have seen specimens of almost all members of Utricularia section Pleiochasia, I can confirm the correct ID of both of Kamil's plants. His darker flowered plant fits all characters of typical U. arnhemica, although its flowers are somewhat smaller, and it does not form huge traps in cultivation. Both may result from growing conditions. The brighter flowered plant, however, differs slightly from "typical" U. arnhemica. Nevertheless, I consider this to be natural variation, and thus regard this plant to fall within the range of U. arnhemica, too. The fact that this plant has an almost glabrous palate (glandular in "typical" U. arnhemica), may be the result of integression from some other member of Pleiochasia. Sorry for having caused confusion about the identity of that plant, Andreas

  6. Hello, In leaves of U. longifolia, a distinct midrib would be clearly visible, especially in young enfolding leaves. ;) There's something else than botany?? ;);) Andreas
  7. Hello, That's U. praelonga. You mean "U. heterophylla", do you, i.e. with two kind of leaves? 'dichotoma' means "forked", and this epithet reflects the flower morphology of U. dichotoma ;). Andreas
  8. Hello, 1 = D. capillaris 2 = D. natalensis complex (i.e. D. natalensis, D. dielsiana, D. venusta) 3 = D. spatulata All the best, Andreas
  9. Hi Jeff, Soil for P.jarmilae/chuquisacensis: clay and sand over sandstone. Detailed description of the habitat in Beck et al. 2008. ;) Andreas
  10. Hello Daniel, Then it's from Kamil ;) All plants in cultivation (which are not many yet) originate from Diamantina, where D. schwackei is endemic to. Andreas
  11. Dear Daniel, Congrats! It seems like your plant (in vitro from Kamil or seed-grown?) is a little bit faster than my plant, which I grew from seed that Fernando sent me 2 years ago. My plants still look like yours on photo number 3 ;). Thus I will have to be patient... ;) Why? I have tried several Drosera crossings over the last 10 years or so, and I made the experience that you can litterally hybridize any species, as long as you stay within the section borders! For example, crosses between D. ascendens and D. slackii, or D. capensis and D. graminifolia did produce viable seed. The seedlings are still too small, but they are growing! Same for "strange" crosses that fellow CPers made, like D. neocaledonica x spatulata, or D. neocaledponica x aliciae. All the best, Andreas
  12. Hello Jim, Yes, that's an extra stamen. Lentibulariaceae usually have two of them (by reduction; normally members of the plant order Lamiales (the mint allies ;)) to which Lentibulariaceae belong to have 5 stamens. However, in zygomorphic ("bilateral") flowers, there's a strong tendency to reduce flower organs to a minimum (to maintain symmetry ;)). Both stamen in Lentibulariaceae are pressed tight to the style to form a complicated pollination mechanism. Any additional 3rd one -which might appear by chance (a so-called "atavism" if you like to use that term for plants)- does not fit into that well-developed design, and therefore is "squeezed" out of the flower tube. This results in your...erh.... happy male ;). All the best, Andreas
  13. Hola Sebastian, Congratiulations! I'm happy to see that "my" Pinguicula chuquisacensis (or P. jarmilae, if you wish ) still thrives well in the wild ;). I have never seen this plant alive in the wild, only several flat dried specimens and photographs of live plants. This site looks fantastic! Maybe some day I'm going to follow your footprints .... ;) All the best, Andreas
  14. Thanks again to all the organizers! I really enjoyed this fantastic meeting in Mira! And of corse I hope to see you all again in Ghent 2009, and maybe at the next AIPC meeting? ;) PS: I really like this particular photograph: http://www.aipcnet.eu/gallery2/main.php?g2...ageViewsIndex=1 Looks much like a Tour de France press conference, hahaha: "We both would like to declare once again that none of us had shown any plant that used blood doping at any time. Honestly. Not." ;) ;) Andreas
  15. Hello, Very well grown plant, congratiolations for successfully flowering it, Dieter! Martin, ! "Sir" Peter Taylor would call this confusion "unexcusable"! Hahaha ;) U. kamienskii should have a lower lip with 3 lobes divided to the palate! Did you forget?! ;);) Flowers of U. kenneallyi in contrast would be much bigger in size, and they have a spur with an acute tip (not rounded like in Dieter's U. aff. lasiocaulis. U. lasiocaulis is probably the most variable Utricularia species of section (subgenus) Pleiochasia, maybe together with U. dichotoma, considering size and shape of the flowers. Thus, in my opinion, this "aff. lasiocaulis" does still fit well the species concept of U. lasiocaulis s. str. as proposed by Taylor. There's still some confusion about the tropical N-Australian Utricularia species, and several plants in cultivation are not identified properly. For example, Kamil Pasek's "U. arnhemica" are really nice and well growing plants. But they are certainly NOT U. arnhemica for various reasons! ;) All the best, Andreas
  16. Dear Sean, I have drawn the estimated range of D. hilaris in green, the known distribution of D. ewricgreenii in red (map by google earth, 2007). Actually, there's one single record of a D. hilaris collected even further north of the range of D. ericgreenii. This is a herbarium specimen collected by Mrs. Esterhuysen on Du Toits Kloof Pass in 1956. No further records of D. hilaris from that area. Mrs. Esterhuysen was a very experienced trustful plant collector in South Africa, thus no doubt she collected that D. hilaris on exactly that place. Further studies will be necessary, and I would love to visit that mountain inland population of D. hilaris on day. All the best, Andreas
  17. Hi Daniel, Well, the differences between a BMW and a Mercedes are not very big, too - both of them are cars ;). But that's it! ;) D. hilaris forms a tall distinct stem of up to 80 cm or more in legth. - The stems of D. ericgreenii are stunted, not taller than about 10 cm. Like already mentioned above, D. ericgreenii has clearly developed stipules, whereas those of D. hilaris are reduced to tiny setae. The apex of the lamina is acute in D. hilaris, but rounded in D. ercigreenii, with unifacial marginal tentacles (which are absent in D. hilaris). Flowers of D. hilaris are twice the size of those of D. ericgreenii, and stigmatic tips are distinc in both species, too. Of corse you can descide to call this just natural variation of D. hilaris. However you would have to include D. ramentacea and D. esterhuyseniae into D. hilaris then, too! ;) All the best, Andreas PS: of corse I think that D. ericgreenii is a good species, which is well distinct from realted species. Otherwise I would not have described it as a distinct species, hahaha! ;)
  18. Hello all, A new Drosera species has been described from the Cape area of South Africa (the article was printed today, thus that’s a brand-new species! ;)) Drosera ericgreenii A. Fleischm., R.P Gibson et Rivadavia See: Fleischmann, A., Gibson, R. & Rivadavia, F.: “Drosera ericgreenii (Droseraceae), a new species from the fynbos of South Africa”. Bothalia 38(2): 141-144. (2008). The article contains a detailed description of the new species, including notes on habitat, ecology and taxonomic affinities. A comparison with its closest relative - D. hilaris - is provided, as well as a b/w-drawing to illustrate D. ercigreenii, a distribution map of D. ericgreenii and D. hilaris. The article includes an identification key for all known stem-forming Drosera species of the Western Cape area. This new species was named in honour of the South African CP expert Eric Green, who discovered countless localities of carnivorous plants in South Africa, and who originally discovered several new species of Drosera (including D. slackii, D. rubrifolia, D. coccipetala, D. cistiflora ‘Eitz’, D. afra, and others. All of which have been described without even acknowledging Eric’s invaluable help or that fact that he originally discovered those plants!). Moreover, Eric is the seed source of almost all South African Drosera which entered cultivation worldwide since several decades! Eric, thank you again for your kind hospitality when Fernando, Robert, Kirk, Stew and I visited South Africa in 2006; for all of the inspiring discussion on CPs, but especially for botanising and exploring the Cape area, for sharing your experiences and discoveries with the CP community, and for helping to introduce so many of those South African beauties in cultivation! Without your efforts, the CP world would not be that rich in so many beautiful South African sundews! Robert, Eric and Fernando in Capetown, September 2006. And finally a few photos to illustrate the new sundew: Habitat of Drosera ericgreenii: fynbos vegetation near the town of Franschhoek, Stellenbosh, Western Cape Province, South Africa. “Fynbos” is a typical vegetation type of the Cape floral area, it is draught and fire adapted ericoid scrubland (“fynbos” is derived from Afrikaans language and means “fine bush”, referring to the usually small, needle like leaves of many species growing there. Its general appearance is similar to what is called “garrigue” or “phrygana” in the Mediterranean, “campos rupestre” in Brazil, “chaparral” in the American West or the “open heathlands” in Western Australia). Drosera ericgreenii prefers to grow in slight shade of shrubs or rocks, on rather dry, sandy soil. Note the very hairy scape of Drosera ericgreenii, which is ascending from the base. In D. hilaris, the scape is growing upright from the centre of the plant. Close-up of the enlarged unifacial glands at the margins of the leaf tip. Drosera hilaris, for comparison, does only have sticky glands with knob-like heads all over the leaf surface. Comparison of the two related species Drosera hilaris and D. ericgreenii (photo of D. ericgreenii by Fernando Rivadavia). Note the conspicuous reddish stipules of D. ericgreenii. In D. hilaris, the stipules are barely visible, as they are reduced to tiny setae. Flower of D. ericgreenii. Drosera ericgreenii in cultivation. I grow this plant under identical conditions to D. hilaris or D. ramentacea (i.e. deep pots up to 30 cm, 50:50-sand:peat mix, substrate only moist, not soaking wet year round, in full sun in my cool greenhouse, a lot of air movement for cooling and to prevent rot). It’s a South African montane species, and therefore somewhat demanding in cultivation (for sure not a beginner’s plant!). Like several other mountain sundews from the Cape (D. glabripes, D. hilaris, D. ramentacea, D. regia) it prefers cool temperatures, especially of the soil. If the roots get exposed to warmer temperatures for too long, the root system is likely to be damaged and will rot easily. However, under good growing conditions this species can be grown from seed to flowering plants within 3 years! I don’t have any spares of D. ercigreenii at the moment, but have sent all of the seed I could harvest from my cultivated plants (it is self-fertile, but not selfing, like most South African Drosera) to some experienced friend growers fro propagation and further distribution. Hopefully this nice plant will enter some more Drosera collections worldwide soon! All the best, Andreas
  19. Hello Dani, I have observed nodding flowers in all plants of D. roraimae on Kukenán and Roraima-tepui in the wild, as well as in cultivation. It seems like all "forms" of D. roraimae with glandular scapes and calyx have nodding flowers. Interesting, isn't it? Me too, I assume it's to protect the anthers and stigma from heavy rainfall. On the other side, the often sympatrically growing D. hirticalyx has upright flowers at anthesis... For sure there are several different "forms" of D. roraimae out there. I personally know of at least 3 of them, which all are waiting for formal description ;) Fernando? ;) All the best, Andreas
  20. G’day mates! I have just returned from a very successful 3 week trip through Western Australia. Within 10 days of field trips with my CP colleagues Thomas Carow and Jan Schlauer I have seen 70 species of CP in the wild (Cephalotus follicularis, 9 species of Utricularia and an incredible 60 species of Drosera!). Four days of additional field trips with Allen Lowrie have added another 25 species to that list! Together with the five CP species I have seen on the field trip to the Blue Mountains, this is an odd 100 species in total. Not bad at all! ;) As I have made tons of photographs on these expeditions, it will take some time to sort out those for publication here on CP UK forum. But I promise to keep them coming! ;) I’ll start with a spectacular large flowered annual Utricularia species: U. petertaylorii. This species grew in large populations together with U. multifida in soaking wet sandy clay substrate over a laterite layer in seepage habitats in the Brookton area. U. petertaylorii (the lilac patches in the photo above) seems to prefer the slightly deeper, waterlogged depressions, whereas U. multifida (the pink patches in that “meadow”) grew in soil that already had started to dry out. It usually grew near big patches of rather stunted Drosera gigantea (yellow spots in the photo). Flowers of both U. petertaylorii and U. multifda still grow in size during anthesis. Therefore, old long lasting flowers of those species are usually much bigger in size than those flowers that just opened. Drosera gigantea with pollinator: a hover fly (Syrphidae - Allen told me that they are called “delta wings” or “B52 bombers” in Australia, due to the typically spread wings in resting position. Those names do fit well in my opinion ;)) Greetings from down under, more soon, Andreas
  21. Hi, No, that location was already included in Jan's map and listing ;) Greetings from down under (currently in Duncraig, WA), Andreas
  22. Hi Martin, I don't want to dissapoint you, but in my opinion, that's P. vulgaris ;) Nice photograps nevertheless! I hope you had an interesting biking tour! Andreas
  23. Hello, Cleistogamous flowers are produced in some Utricularia species (U. subulata, U. triloba, U. juncea, U. welwitschii for example) if growing conditions are not optimal for producing chasmogamous flowers. In my opinion, it's mainly daylength or intensity of light, maybe even temperatures. Several greenhouse grown location forms of my U. subulata develop their pretty yellow chasmogamous flowers only in spring and autumn, but not in summer (too hot?) or winter (few light, too cold?). Btw, I have never found any cleistogamous flower in any subulata I have seen in the wild (neither in plants in Venezuela, nor SE USA, nor Thailand, nor Zambia, nor Sierra Leone). However, several of these plants which I have raised from seed now produce cleistogamous flowers under my growing conditions some part of the year. And: Christian's plant is not a U. subulata, but a U. triloba! ;);) All the best, Andreas
  24. Hi, I think the Drosera is D. communis (petioles are too wide and too short for being D. intermedia). The "Utric" is Burmannia bicolor, a Burmanniaceae, as Fernando already mentioned. Not carnivorous, but nevertheless not boring, isn't it Fernando? ;) All the best, Andreas
  25. Dear Alexander, I would not rely on established distribution patterns in aquatics, especially not in such plants that are easily dispersed by migrating birds - like aquatic Utricularia are. ;) For example, I have just confirmed U. aurea from Madagascar, which was not known from anywhere in that area so far. The closest populations known so far are in SE Asia. However, it could have easily been introduced to Madagascar by water birds. Same for U. bremii, which is much more common in continental Eurasia, as you have stated correctly. Thus Andy has made the first record of U. bremii from Britain! Congrats Andy, one more native CP species for England! ;). All the best, Andreas
