A Revision of Triodia including Plectrachne (Poaceae, Eragrostideae, Triodiinae)

摘要: On the basis of morphological data presented herein, Plectrachne Henr. is included in Triodia R.Br. This congeneric change requires 15 new combinations and three nominations. In sens. lat., 11 species are proposed, one subspecies raised to specific rank, while six varieties reduced synonyms. For first time, melvillei T. schinzii recorded for South Australia, bunicola Victoria, mollis Queensland marginata New Wales. Although probably monophyletic, as here interpreted widely variable. Thus, a classification nine informal infrageneric groups proposed.
