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).
