Nearest related to A. fatiila and A. hastata, but differs from 

 the former in the strict habit and the dark leaves, from the latter in 

 the narrower, not hastate, leaves, and from both in the bracts, which 

 are thmner and not foliaceous at the apex. The leaves resemble 

 those of Polygonum la^athifoUum, hence the name. It grows on 

 alkaline flats, at an altitude of about 1500 m.
