  1. Hopefully he eventually replies to your email. The wikipedia site is quite good, apart from it's confusion over the location of Maringma and it's missing that Heliamphora heterodoxa occurs on Waukauyengtipu. Hopefully they will update it sometime. What is interesting is that the tepuis on the North and East of the Chiimanta massif seem to have fewer Heliamphora species than those to the southwest; I wonder if this is due to being explored less. It would also be interesting to know how high they extend on Murei tepui. LeeB.
  2. People are selling both H. exappendiculata and H. pulchella labelled as coming from Apacapa; to confuse matters as well as the H. exappendiculata collected by Steyermark in 1953 on Abacapa he also collected H. pulchella 75776 on Apacara. I strongly suspect like you do that Apacapa is an error or variant spelling of Abacapa. However as the source of the plants is Wistuba only he can clear this up; if there is an Apacapa tepui it must be a very small one not on any map of Chimanta that I have been able to find. LeeB.
  3. you are going to find that a lot with tepui names. They could have been named by a character in Terry Pratchett's diskworld series who is a professor of cruel and unusual geography. The same name is sometimes applied to two different tepuis and the same tepui is sometimes given two or more names. And different people describe the same tepui as being in two different places. Some of the Testugos chain have being given different names; Maringma has been described as being in different places; a sundew described as being from Yakon tepui is apparently from Maringma, and Waukau
  4. A new species of Nepenthes from Sulawesi is described here: http://www.ingentaconnect.com/content/nhn/blumea/pre-prints/content-nbc_blumea_0355 and a new section in the genus Nepenthes is created for the species related to N. tentaculata. LeeB.
  5. If you want more exact locations for Genlisea you should contact Dr. Andreas Fleischmann; he has written the monograph on the genus. LeeB.
  6. Have a look here: https://www.flickr.com/photos/epmallory3/albums/72157631817597942 There are lots of nice pictures of carnivorous plants from Belize. They show Genlisea and also Drosera capillaris; D. brevifolia has also been recorded from there. I haven't seen any exact locations. LeeB
  7. Catopsis berteroniana is recorded from Rio Dulce. And as Genlisea filiformis is recorded from Belize as well as Guatemala it might be found in that area. LeeB.
  8. Guatemala has lots of Utricularia, if you go to the Carnivorous Plant Society's FAQ page look up Carnivorous Plants of Central America and the Caribbean you will find a list. Drosera should occur there too, as does Genlisea filiformis. Pinguicula clivorum, P. crenatiloba, P. lilacina, P. mesophytica, P. moranensis and P. orchidioidesa all occur there. P. mesophytica has been found in the department of Chiquimula on the middle slopes of Montana Norte to El Jutal at 1217m and at Cerro Brujo, S.E. of Conception de las Minas at 802m. P. moranensis has been found at Chichicastenago at 2200m
  9. Did you keep records of the number of each colour variant compared to the total number of seedlings? Were there equal numbers of each colour variety or did some predominate? LeeB.
  10. Apparently Utricularia stellaris occurs there; it is a widespread species also occurring in Africa, Asia, Madagascar and the Comoros Is. As far as I know there are no Drosera there; and there are certainly no Nepenthes. So it may be the only carnivorous plant there unless any other Utricularia occur there. LeeB.
  11. Interesting. Sounds like it is a good paper. Are you planning on doing a complete overview paper on all the South American Drosera anytime? That would definitely be worth reading (as would one on all the African Drosera). LeeB.
  12. Interesting thoughts. Looks like more experimental study is needed. Also the space inside the trap and the nutrient supply is limited so the algae cannot keep dividing exponentially forever ; their population would run out of food and crash sooner or later anyway. LeeB.
  13. Interesting; yet if they secrete digestive enzymes they should not work on their own tissues. Just like toxic animals are immune to their own toxins. And our own stomachs are not digested by the hydrochloric acid that they contain. Basically the plant tissues should be able to evolve an immunity to their own digestive secretions; and not have to wait until the prey starts to breakdown after death to digest it. Unless they are relying on other organisms to break down their prey for them as S. purpurea does. LeeB.
  14. Though it does raise the question of why it has to kill the algae before it can digest them; I would have thought the secretion of digestive fluids into the trap would do the job whether the algae were alive or not. LeeB.
  15. Just one thing, New Zealand doesn't only have the T form. The number of leaf points increases with the plants age; also when growing amongst competing vegetation the plants produce fewer leaves with longer petioles and more points per leaf. Plants growing amongst dense vegetation on the Kopuatai dome swamp and in Northland can have more than twenty points per leaf although around a dozen is commoner. There are pictures on the NZCPS website and in Bruce Salmon's book showing this. Plants growing in the open and at altitude are the ones that have smaller leaves with only two or four points.
  16. Does Drosera indica also occur in your area? It seems to occur widely in East and South Asia as well, although perhaps not as far north as D. peltata. LeeB.
  17. D. peltata doesn't only occur in south and south east asia, it is fairly common in the more southerly parts of east asia.The online Flora of China lists lots of Chinese provinces it occurs in. LeeB.
  18. D. arcturi grows in Tasmania and the colder parts of New Zealand so I think you could grow it outside; also D. stenopetala (found only in the colder parts of New Zealand and the Auckland and Campbell Islands to the South) and D. unifolia (which comes from the far south of South America). These are amongst the most cold tolerant of Southern Hemisphere Drosera. LeeB.
  19. As well as growing in Japan at the north of it's range D. spatulata grows in Tasmania and New Zealand at the south of it's range. It grows with the decidedly non tropical D. arcturi and D. stenopetala in the more southerly parts of New Zealand. Anything that can survive a winter in Fiordland or Southland is not a tropical plant. I suspect your plant originated in the temperate part of D. spatulata's range. LeeB.
  20. There is a new paper on the trapping mechanism of H. nutans here: http://rspb.royalsocietypublishing.org/content/280/1753/20122569.full It is similar to that used by Nepenthes. LeeBr.

  22. Thanks for that Andreas, I can't wait to see your monograph either. Sorry I didn't notice the photo a month ago :-( It is an excellent idea to have a website where you can continuously update information on the species such as their distributions. So there are three Genlisea species in west Africa, that's interesting. I saw the species list for your book on the Redfern Natural History website; so G. subviridis and G. taylorii are no longer considered valid species? Looks like the book will keep me busy for a while. Now that you have got this book out of the way are you planning to publis
  23. I came across this photo of G. stapfii here: http://eol.org/data_objects/21918485 It is a nice enough photo but what is really interesting is the location it was taken in; it was in Benin and maps showing the range of Genlisea have a big gap between Liberia and Ivory Coast to the west and Eastern Nigeria and Cameroon to the east. Benin is squarely in the middle of that gap. Probably Genlisea will turn up elsewhere in that gap where conditions are suitable. LeeB.
  24. There is an abstract of a paper discussing this here: http://onlinelibrary.wiley.com/doi/10.1111/j.1365-3040.2011.02382.x/abstract It appears that N. ampullaria does get some of its Nitrogen from leaf litter falling in it's pitchers. The Wikipedia article on N. ampullaria has links to some other abstracts of papers on this. You could also try searching Google Scholar for "Nepenthes ampullaria" and "Detritus" to see if there are any other papers on this topic. LeeB.
