Jean, thanks for those links; I used to visit the CactiGuide.com years ago when trying to identify my Rhipsalis plants but I'd not seen the Rhipsalis.net site before. I don't think I ever read that article by Geoff Stein and it is interesting but I tend to disagree with the idea that Rhipsalis tend to be tropical/thirsty plants and aren't very drought tolerant. In my experience they are quite tolerant of dry soil for long, extended periods. I have four or five Rhipsalis plants hanging in a tree behind my deck that rarely get watered and although the humidity is quite high with being right on the edge of the waterway these plants still go very, very dry. To get water to that area I have to drag the hose across one deck, through the long screened porch and out another door to the other deck to be able to reach the plants in that tree ... and then I have to drag the hose back out again. I'm too lazy to do that on a regular basis.
I agree, the plant in question definitely appears to be R. grandiflora and should be moved to that location in the database.
