Abstract　 Xizangia serrata Hong , the sole species of the monotypic genus Xizangia

X izangia and X .serrata are both reduced to synonyms.
Key words　 X izangia Hong ;Synonym
In the course of preparing an account of some genera in the Scrophulariaceae for F l.
Yunnan., my attention was draw n to Xizangia Hong , a monotypic genus w hose sole
species , X .serrata Hong , was described from a single collection(B.S.Li , Z .C.Ni and
S.Z.Cheng 6601 , PE)from Bomi County , Xizang , China.I w as struck by the similari ty
between this plant and Pterygiella bartschioides Hand.-Mazz., a species described from
northwestern Yunnan , China.
Closer examination of more specimens has show n conclusively that X .serrata is indeed
the same species as P.bartschioides.This results in the follow ing synonomy :
