| 摘 要： | 本文研究、分析了禾本科33个族、174个属(632种)的花的性状；讨论了重要性状演化
的趋势。根据花、尤其花中鳞被的比较形态，把禾本科植物的花概括为三大类型七个亚型：竹
型(包括真竹亚型，稻亚型、芦竹亚型、针茅亚型)、早熟禾型(含早熟禾亚型)和黍型(包括画眉
草亚型，真黍亚型)。其结果与花的基本类型相对应的大类群，以及与幼苗基本类型、颖果基本
类型相对应的大类群是一致的，即竹亚科、稻亚科、芦竹亚科、针茅亚科、早熟禾亚科、画眉草亚 科，黍亚科。

| Abstract: | The flowers of the representative species of 33 tribes and 174 genera were
investigated for the purpose of Gramineae systematics. Discussed in this paper are ten impor-
tant flower characters, 6 of which are of the pistil, two of the androecium and two of the lodi-
cule. The morphology of lodicules is of particularly great value in systematics, it consisting of
nine forms: membranous-flattend, tongue-shaped, chaffy-peltate, hooded or helmet-shaped,
spade-like, longitudinally folded, cucullate, top-shaped and funnel-thaped. Its numbers per flo-
wer may be: numerous, triple, dual, single and absent. On the basis of these ten characters,
three major types and seven subtypes of the flowers of Gramineae may be recognized: Bam-
busoid (including True Bambusoid, Oryzoid, Arundinoid, Stipoid), pooid (with Subtype Po-
oid only) and Panicoid (including Eragrostoid, True Panicoid). As a result, The major groups
corresponding to the flower basic types agree wih those divided according to the basic types of
seedlings and caryopses. They are seven subfamilies: Banbusoideae, Oryzoideae, Arandinoi
deae, Stipoideae, Pooideae, Eragrostoideae and Panicoideae. |
