ORDER 129. GRAMINEAE. (GRASS FAMILY.)

_Grasses, with usually hollow stems_ (culms) _closed at the joints,

alternate 2-ranked leaves, their sheaths split or open on the side

opposite the blade; the hypogynous flowers solitary in the axils of

imbricated 2-ranked glumes_, forming a 1--many-flowered _spikelet_; the

lower glumes (1 or usually 2) empty, the succeeding _flowering glumes_

enclosing each a somewhat smaller and usually thinner scale (called the

_palet_) and 2 or 3 very minute hyaline scales (_lodicules_) at the base

of the flower. Stamens 1--6, commonly 3; anthers versatile, 2-celled,

the cells distinct. Styles mostly 2 or 2-parted; stigmas hairy or

feathery. Ovary 1-celled, 1-ovuled, forming a seed-like grain

(_caryopsis_) in fruit. Embryo small, on the outside and at the base of

from, sometimes permanently adherent to, the palet.--A vast and most

important family, as it furnishes the cereal grains, and the principal

food of cattle, etc. The terms _flowering glume_ and _palet_ are now

adopted in place of the _outer_ and _inner palets_ of previous editions,

while for convenience the term flower is often retained for the flower

proper together with the enclosing flowering glume. (See Plates 7--15.)
