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: Not *necessarily*, a distribution can have multiple peaks.
gollark: Equivalently, if you take a random person you know nothing about, the probability that their height is between, say, μ-3σ and μ-2σ (154cm to 164cm) is lower than the probability of it being between μ-2σ and μ-σ (164cm to 173cm).
gollark: The further away from the average height you get, the rarer people with that height are.
gollark: If you imagine plotting a bar graph with *extremely* narrow bars with all the information on heights you get, then the tops of the bars will form a shape like that.
gollark: No, not really.
