Description

It produces a distinctively flattened caudex, often with lobes that spread out.

The creeping shoots grow throughout most of the year, though each will periodically die back and be replaced from the central caudex root stock. In dryer conditions it can become deciduous. The green creeping foliage can reach 4 meters or more in height.

It is an extremely widespread and variable species, with several extremely distinct varieties.[1]

Threats and conservation

It is threatened from illegal collecting for traditional medicine, as well as for the horticultural trade. As a consequence it is listed as Vulnerable.[2]

gollark: Oh, NOW it pings me somehow?
gollark: You have a reasonable point that you can be nice to people inside a conversation but (possibly inadvertently) non-nice to those outside it. I think niceness within conversations is more important, as people outside them can more easily choose not to participate in them, but this doesn't work excellently. Banning discussion of anything some people do not like reading is *a* fix for some of this, but I don't like the tradeoffs, given the wide range of things in this category. Isolating that elsewhere is also not good for various reasons I indicated before. A generalized rule-4-y approach could end up doing basically the same thing as preemptively banning it, and people seem dissatisfied with "ignore the channel for a bit". Thus, I'm unsure of how the issue can be solved nicely and it's worth actually investigating the options.
gollark: What a strange name.
gollark: You are to wait while I:- type- think- move a mouse cursor around somewhat- get distracted by unrelated topics repeatedly
gollark: Too bad, you are to wait.
