Chinese Ephedra

Ephedra sinica Stapf

Comments

provided by eFloras
It seems likely that Ephedra sinica var. pumila Florin, Kongl. Svenska Vetenskapsakad. Handl., ser. 3, 12: 11. 1933, will also be found in China. It differs from var. sinica in its very low growth habit, often curved or involute branches, shorter nodes, and seed cones with only 2 or 3 pairs of bracts. The most appropriate taxonomic rank for this taxon is uncertain.

This species has medicinal properties.
