Dyckia distachya

A rheophytic Dyckia that grows on basalt rocks in the rapids of rivers in southern Brazil, where it is regularly submerged by floods. Hydroelectric dams on the upper Uruguay and Pelotas rivers flooded most of its known sites, and it survives largely through rescue and ex situ conservation.

Recorded elevations 193–650 m, median 450 m (7 records), along river valleys well below the surrounding plateau.
