Hi List,
A while ago some was asking how to tell D. capilaris, D. brevifolia
and D.rotundifolia apart. I notice the question comes up now and again
so here are some crude pics of what they look like.
-------------------------Text-of-forwarded-mail--------------------------------
Both D.capilaris and D.brevifolia grow almost always together.. I've
been down to Fl. on CP trips a number of times and just this year
have I become good at telling the two apart. Also, there is D.
intermedia but with it's upright growth, it is easy to tell it apart
from the others. Below I've (tried) to draw the leaves so you can
see the differences.

The drawings are crude but you can see the important data: leaf shape
and about where the tentacles begin.
