What type of category does Stachyurus and Pleioblastus have in common?
Stachyurus Stachyurus is the only genus in the flowering plant family Stachyuraceae, native to the Himalayas and eastern Asia. They are deciduous shrubs or small trees with pendent racemes of 4-petalled flowers which appear on the bare branches before the leaves. The plants have leaves with serrate margins. Stachyuraceae contains a single genus with eight species.
Pseudobarbus Pseudobarbus is a ray-finned fish genus in the family Cyprinidae. The type species is Burchell's Redfin ("P. burchelli"). The scientific name is derived from the Ancient Greek "pseudes" ("false") and the Latin word "barbus" ("beard", in reference to the barbels of barbs). This genus contains some (and might contain all) of the South African redfins. It was originally proposed as a subgenus but has since been found worthy of recognition as a full genus.
