Order CYII. GRAMINEiE. 
Flowers usually some hermaphrodite, often accompanied by others 
more or less imperfect sexually, each placed in the axis of a membra- 
nous bract (pale), which with the flower is enclosed in another boat- 
shaped bract of firmer texture (flowering glume). Flowers one or more 
in a spikelet, which has a pair of similar bracts (emptj r glumes) at 
the base. Perianth of two or more minute hypogynous scales, which 
are sometimes absent. Stamens hypogynous, usually 3 ; filaments 
long, thread-like ; anthers pendulous. Ovary 1-celled; ovule 1, basal, 
anatropous; styles 2, long or short; stigmas feathery or hairy. Fruit 
a caryopsis (grain), free or sometimes adhering to one or both of its 
enfolding bracts. Seed adnate to the pericarp, containing abundant 
floury albumen, with the embryo on one side at the base. — Herbs, 
rarely shrubs, with distinctly-jointed hollow stems, narrow leaves with 
open sheaths split to the base, and panicled racemose or spicate in- 
florescence. Distrib. One of the most cosmopolitan of orders.
