营属(Themeda Forsskal)及其有关属的分类与考证

A STUDY ON THE SYSTEMATICS OF GENUS THEMED FORSSKAL

摘要:

对菅属（ThemedaForsskal）的命名与合法性历史进行了考订，确定合法的属并列出了异名录；鉴于原AnthistiriaLinn．f.属较庞杂，属的概念（范畴）有较大变化，本文采用P．Forsskal及E．Hackel和W．D．Clayton的Themeda属的范畴，对已发表的原归用于Anthistiria和Themeda等属的种（双名）逐一作了考订，以明确它们的隶属关系并转隶于10个不同的局；对Themedan属自P．Forsskal（1775）建立以来的系统分类研究状况作简短的回顾，并对所存在的问题作了简述．

Abstract:

This paper is the first part of the study on the system and evolution ofgenus Themeda Forsskal. The nomenclature of Themeda Forsskal, Anthistiria Linn. f. andrelatives were reviewed. The legitimate name Themeda published by Peter Forsskal andseveral synonyrns were listed. Genera Themeda and Anthistiria being exadrined and correctedwere transferred into 10 genera, viz. Themeda Forssk. (70 binom. & 33 spp.), ExothecaAnderss. (1 binom. & 1 sp.), HyParrhenia Anderss, ex Fourn. (13 binom. & 7 spp.),ISeilema Anderss. (7 binom & 3 spp), Hyperthelia W. D. Clayton(1 binom. & 1 sp),Germainia Ba1ans. & Poitr. (2 binom. & 1 sp.), Pseudanthistiria (Hack.) Hook. f (1 binom.& 1 sp.), Tristachya Nees (1 binom. & 1 sp.), CymbOPogon Spreng (1 binom. & 1 sp.),Elymandra Stapf (1 binom. & 1 sp.). Four dubious specific names are presented. Historicalstudy on the systematics of Themeda and allied studies were briefly reviewed. The problemsof evolutionary trend and systernatic treatment have been proposed.
