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.
