  1. Hi there! Last week I went to the Serra do Ibitipoca, in Minas Gerais state, Brazil. These highlands are home of four Drosera species (D. montana, D. tomentosa, D. communis, and the magnificent D. villosa) and also several species of Utricularia and some of Genlisea, which I couldn't found with flowers as it is the beginning of the winter down here and most species flowers during spring and summer. Some photos: Drosera communis Drosera montana Drosera villosa Drosera villosa and Utricularia reniformis Drosera tomentosa var. glabrata You can check all the photos here: https://www.facebook...70251137&type=1 All the best,
  2. Fantastic photos and plants, Dieter! May I ask what is these red rocks you use as media? Is it laterite? The plants seem to appreciate it! They are splendid! All the Best,
  3. Hi Aymeric, The D. graminifolia "Nortensis" are the D. spiralis plants from the northern range of this species, around the towns of Grão Mogol to Itacambira. This paragraph of the paper deals with this "morphotype": All the best,
  4. Hi there, A new article on Brazilian Drosera taxonomy just got published: Gonella, P.M., Rivadavia, F. & Sano, P.T. (2012) Re-establishment of Drosera spiralis (Droseraceae), and a new circumscription of D. graminifolia. Phytotaxa 75: 43-57. http://www.mapress.c...p00075p057f.pdf Here the abstract of the paper: "Drosera graminifolia and D. spiralis have long been considered conspecific, but new morphological and ecological data support the recognition of these taxa as distinct species. Both species are here described and illustrated, including observations on ecology, habitat, and conservation status, together with a distribution map, line drawings, photographs, and a table containing the distinctive characters." Here are the answers for those who ever asked themselves about the differences between Drosera graminifolia and D. spiralis (as you can see in the article, there are many)! Here you can see a brief illustrated guide, showing the main differences between both species: https://www.facebook...70251137&type=1 And here, one of the figures of the article, illustrating Drosera graminifolia: In case you want the pdf of the article, just PM me sending your email address! All the best!
  5. Hi Dani, Beautiful plant you have there! But some features you showed are not that uncommon! D. spiralis quite often have small leaves along the scape (with stipules and everything), and the tentacles on the sepals is a common characteristic of this species (one of the several that distinguishes it from true D. graminifolia). Here some photos: BUT, fused leaves and lateral shoots are not that common! In our last trip to Minas Gerais we found lots of mutant plants, including some very nice ones with the sepals completely transformed into "normal" leaves! Here some photos by Adilson: Cheers,
  6. Hi there! Here some new photos of this species taken by a botanist colleague from Brazil (incl. a plant with two open flowers at the same time): http://www.plantsystematics.org/cgi-bin/dol/dol_terminal.pl?taxon_name=Drosera_quartzicola&rank=binomial Worth checking out! All the Best,
  7. Adam & Peter, thanks for the comments! Indeed the landscape from Serra da Canastra is breathtaking! Such a lovely place! Dave - in fact we know of another population of this species distant about 25 km of this one that is growing on a "dripping moss-covered vertical sandstone wall". Unfortunately we have only photos of those plants. I hope I can go there soon to check if they are really G. nebulicola. All the Best,
  8. Hi guys, Thanks for the nice comments! :) Dani - yes! Fortunately my camera survived, even after taking that bath! Fernando - for sure! The Serra da Canastra is so close to home (ok, not that close, but much closer than several other CP habitats we had been to) and there's so much to explore. Hopefully I'll be there again soon! ;) Aymeric - that's a good question that we also did ourselves. At the time I was there, I've seen no insect close to the plants. In fact I think it would be impossible to an insect small enough to be the pollinator of this species to get close to those plants, since the wind and spray from the waterfall is so strong that even for myself was a challenge to reach the plants! Also, it's quite unlike that the Casca d'Anta waterfall become so dry in some moment of the year that the spray stops enveloping the flowers in a water droplet - it's a huge waterfall with lots of water. But I've never been there during the high of the dry season, so I cannot be sure. But as you can see I found some fruit at the time I was there which, I believe, were result of auto-pollination. I also observed fruits in my cultivated plants being produced without hand pollination, so it's certainly possible (which is interesting, since it's a quite rare event in the other species of subgenus Tayloria, which all need to be hand pollinated in cultivation). So, those plants may rely mainly (if not only) on auto-pollination, in my opinion. All the Best,
  9. Hi Dani & Aymeric! Thanks for the comments! :) I really hope this species will become common in cultivation soon, since it's so rare in nature! All the Best,
  10. Hi there! I just posted photos of the fifth new species, Genlisea nebulicola, both in the habitat and in cultivation: http://www.cpukforum.com/forum/index.php?showtopic=44561 - habitat http://www.cpukforum.com/forum/index.php?showtopic=44562&pid=310400&st=0entry310400 - cultivation All the Best,
  11. Hello all, Some photos of this species in cultivation! It seems to be a very easy grower, flowering constantly. For habitat shots, please look at the “Carnivorous Plants in Habitat” forum! All the Best, Paulo
  12. So, before leaving the Serra da Canastra, some other beauties of that region: For photos of this plant in cultivation, please look at the “Carnivorous Plants in Cultivation” forum! ;) I hope you enjoyed it! All the Best, Paulo
  13. Hello all, As you must have seen in this fantastic report by Andreas - http://www.cpukforum.com/forum/index.php?showtopic=44386 - five new Genlisea species from Brazil had just been described by Andreas Fleischmann, Fernando Rivadavia and myself. One of this new species is the rare Genlisea nebulicola, a small species endemic to the Serra da Canastra region in Minas Gerais State, SE Brazil. This species was first discovered by a friend of Fernando, and, before March of this year this species had been collected for herbarium only once by Fernando in 1999. As we had only that "old" material to study and describe this species, a new trip to that region was necessary so we could have more material for the species' description. So, by the end of March I went on a trip to Serra da Canastra to collect new material and try to find new populations of this rare taxon. Unfortunately, I couldn’t find any new population, but only the one already known. So here are the first digital photos of this unique plant! :) The plants grow at the base of one of the highest waterfalls in Brazil, the Casca d`Anta waterfall with 186 m high. It is possible to see and hear the waterfall even several km away: The Casca d`Anta waterfall. Getting closer Growing between mosses over the rocks close to the waterfall I found some rosettes – there it was! The rare Genlisea nebulicola! Take pictures of these plants was a real challenge since the spray from the waterfall was so strong that the lens of my camera was constantly wet! The spray is so strong that nothing grows on the side of the rocks that faces the waterfall, but only on the other side. With the hand as a scale, so you can have an idea of how small the plants are As you can see, the very short flower scapes bear really few flowers The first flower I found wasn’t opened yet… All other flowers I found were completely enveloped by water droplets due to the constant spray from the waterfall A plant with fruits Of the really few flowering plants, this one was certainly the most photogenic! A really nice photograph of this beautiful plant! “nebulicola” means “adhered to clouds”, and I think that this photograph show quite well why we chose this name for this species! Finally, a general view of the rocks ate the base of the Casca d’Anta waterfall. As soon as I turned the camera toward the waterfall to take this picture, the lens got completely wet!
  14. Hi Adam, Do you have any picture of what you call 'typical G. pygmaea'? I ask because there's a lot of confusion regarding the ID of G. pygmaea and closely related taxa - mostly new species that were misidentified as G. pygmaea in the past. It is possible that your plant is a closely related species from Brazil (not yet described) that shares several morphological characteristics with G. pygmaea, but is much more robust (that could explain the different genome sizes). What's the size of the flower? Best Regards, Paulo
  15. Hi Adam, Actually that's G. pygmaea! I can tell you by the very dense eglandular hairs on the sepals (in G. filiformis the sepals are almost glabrous), and the acute apex of the spur (vs. rounded or truncate in filiformis). Interestingly the flower looks too pale, but that can be environmental. Best Regards, Paulo
  16. Hi there, Thank you very much for the nice comments! Daniel - the biggest flower I found had 2 cm in diameter, while the smallest had about 1 cm. I have pictures of the hybrid, I'll upload some and post latter! Ken - Of course yes! It seems that D. quartzicola is a very hard to grow species. It produces really few seeds and is a very slow grower. But I hope it get commoner in cultivation soon. All the Best,
  17. Another flowering plant (until now I've only seen two open flowers of D. quartzicola): close A plant with a juvenile scape: Plants with fruits: During the dry season the plants may lose it's mucilage: But some resistant plants maintain some active leaves, although much smaller than the ones produced during the wet season: Some habitat photos: And here some photos of the small globular trichomes that cover almost all the plant surfaces. We think that these trichomes are able to capture the humidity from the air, as the species that possess it (D. chrysolepis, D. camporupestris, D. graminifolia, D. schwackei, and D. quartzicola) are the ones that grow on extremely dry habitats when compared with most of the other Drosera species in Brazil. They would be very important mainly during the dry season, because even without any rain for many months it is common to see the formation of fog at night and early in the morning on the mountain tops where those species grows: Here the trichomes on the lower leaf surface: That's all! I hope you enjoy it! All the Best,
  18. Hi there! As you may already have seen, Fernando did the announcement of the new species we have just published: http://www.cpukforum.com/forum/index.php?showtopic=43805&pid=307353&st=0entry307353. Here the link to the summary of the article: http://www.mapress.com/phytotaxa/content/2011/f/p00029p040f.pdf However, there are really few photos of this beautiful species on web, so I'll post some new photos so you can know Drosera quartzicola better! This species was first discovered by Fernando in 1996, but only now it was formally published! I have to thank Fernando for letting me help him to describe and publish this amazing plant! Drosera quartzicola is closely related to D. chrysolepis, with which it eventually hybridizes. The main distinctive characteristics of this new species are the very short stem, the upper surface of the petiole without eglandular hairs, petiole and lamina with about the same width, the very short inflorescences, and the dense indumentum of small globular trichomes that you will see below. This is a very rare species and it is considered as Critically Endangered. The photos I'll show here were taken along the last few years, but I never had time to post. But now that the species have a name I decided to finally post them. The photos were taken at different times of the year and in different populations (only four populations are known, all VERY small) and show how this species reacts to the different seasons (basically the wet and the dry season). Lets go to the photos! Here you can have an idea of how big are the plants during the wet season: The epithet "quartzicola" was chosen because this species grows on sandy soil with quartz gravel: Close of the leaves: A very nice group: A very red group: A huge specimen: The same plant, a year latter: The flowering period of this species in concentrated in the wet season, between January to April. The scapes are very short, probably because of the very open habitats where this species grows, where a long inflorescence would easily broke with the constant wind: The flowers don't have anything special when compared with the related species: close
  19. Hi there! I'm really proud as well! This is my first new species! I'll post some new photos of this new species soon! All the Best,
  20. Hi Fernando, Actually, Catolés is a district of Abaíra! ;-) Best wishes, Paulo
  21. Thanks Christian! Unfortunately that's the only good photo I got of U. laciniata; the light wasn't good on that day. Utricularia laciniata vary a lot along it's distribution. Maybe you got plants from other location? The plants from Serra do Cipó looks different from this as well, as does the plants from Chapada dos Veadeiros which have the nicest color and form of this species. Best Regards, Paulo
  22. Thank you all for the comments! It was such a nice trip and I'm so glad you liked the photos! Vic - at Ibitipoca the annual average temperature is about 18º Celsius, during the summer the maximum temp. can reach 30º but is usually lower because of the altitude (about 1400 m a.s.l.). Winter average temp. 12º C, summer average temp. 24º C. About 14h of light during summer/about 10h during winter. The plants were growing directly on the sphagnum or in a very thin layer of organic matter with sand. G. violacea is a annual plant, growing and flowering during the summer and dying at the end of the fall as the winter is very dry in SE Brazil. It returns from the seeds at the begging of the spring with the first rains. It's a quite easy plant to grow. I did many nice trips since December and I hope to post the photos soon! All the Best, Paulo
  23. I saw many leaves of Utricularia reniformis, but no flowers at all... I was almost giving up when... Hahaha! But I did found a real one! Unfortunately the plant was in a very difficult place to get with the camera, but I could not leave without a photo: Utricularia pubescens was growing in almost all wet and shaded places. And there was 3 types of it, with different colors and shapes, sometimes growing altogether! Type 1 Type 2 Type 3 - intermediate Utricularia nana pigmy Drosera villosa! Drosera villosa and D. tomentosa sharing the same rock: More Oncidium Canary bird The moon on its more habitual habitat, the black background: In our last Day we left early, but I had time to record this wonderful sunrise! Flower of the cact with the sunrise in the background And, finishing, me with the ‘sea of hills’ in the background Hope you enjoy it! All the Best,
  24. And a native falcon called ‘carcará’ Finishing the day, the moon on its not-so-natural habitat, the blue background: As we explored almost everything in the previous day, very little left to explore in the next day… but I did found lots of interesting plants. First, the bird fighting with the rearview mirror.  Growing in a wet slope with Sphagnum, Genlisea violacea A plant with darker flowers other Normal ones All of them The same river of the photo of the begging of the post.
