Andreas Wistuba Posted February 16, 2014 Report Share Posted February 16, 2014 This might be the first time, that a picture of this relatively new species (1983) is published anywhere. I took the slide in 1994. There are more and I have to screen through them... I will maybe show a few more soon. Hydnophytum crassicaule and H. vaccinifolium are fascinating terrestrially growing species only known from the alpine zone of Doormantop in West Papua (ca. 3200 meters high): Link to comment Share on other sites More sharing options...
Manuel Reimansteiner Posted February 17, 2014 Report Share Posted February 17, 2014 Hi Andreas, which Nepenthes species is that in the foreground of that picture. Maybe N. lamii? By the way, very impressive image. Actually the 2. Lost Worlds. Regards, Manuel Link to comment Share on other sites More sharing options...
Aurélien Posted February 18, 2014 Report Share Posted February 18, 2014 This one, and H. vaccinifolium reminds me a nice plant which I see many times in the greenhouses of Christian Klein. He displays it to me as a "rounded leaves" variant of H. ramispinum. (Photos from François Mey's blog). Link to comment Share on other sites More sharing options...
Andreas Wistuba Posted February 18, 2014 Author Report Share Posted February 18, 2014 Hi Aurelien, the narrow leaved plant Christian is growing, certainly is H. ramispinum (last picture). The round-leaved one (all other pics) is a bit of a mystery to me. Actually there are two species with spiny caudices known to occur in the area - H. ramispinum and H. confertifolium. The leaf-shape of H. confertifolium fits quite well to the round leaved plant. However according to the type description, H. confertifolium is supposed to have leaves just a few millimeters across. I have a picture of a huge plant in the wild: http://myrmecodia.invisionzone.com/index.php?/topic/46-hydnophytum-spec-round-leaves-spiny-caudex-doormanstop-plant-in-the-wild/?p=121 Interestingly, even though the caudex is so similar, leaves and most of all flowers are completely different.

Aurélien Posted February 18, 2014 Report Share Posted February 18, 2014 Interesting...Christian says that the "true" H. ramispinum (with narrow leaves) give seeds occasionally, but those with round leaves never produce any fruits, even by crossed pollination... Another mystery! Link to comment Share on other sites More sharing options...

Christian says that the "true" H. ramispinum (with narrow leaves) give seeds occasionally, but those with round leaves never produce any fruits, even by crossed pollination... Another mystery! I think many Hydnophytinae are self-incompatible. A few clones of Hydnophytum ramispinum are in cultivation, hence it works - sometimes. The same holds true for H. vaccinifolium. However, only one plant of the round leaved species is in cultivation. All the best Andreas Link to comment Share on other sites More sharing options...

jeff Posted February 20, 2014 Report Share Posted February 20, 2014 have you some info on these 2 species crassicaule and vaccinifolium ? jeff Link to comment Share on other sites More sharing options...
Andreas Wistuba Posted February 20, 2014 Author Report Share Posted February 20, 2014 have you some info on these 2 species crassicaule and vaccinifolium ? jeff Yes, it's in: P. Royen Alpine Fl. New Guinea 4: 2672 1983 As this is a new publication that still falls under copyright, I do not wish to post a scan here.

Andreas Wistuba Posted June 17, 2014 Author Report Share Posted June 17, 2014 Hydnophytum crassicaule - I just found two more pictures showing this fascinating species. Both were taken on Doormanstop in 2000: Link to comment Share on other sites More sharing options...
