CVII. GRAMINE^E. 
\_Milium. 
floret. Glumellas 2, subcoriaceous below, each with a tuft of 
short silky hairs at the base ; outer one mucronulate or with a 
very short awn below the point. Stigmas cylindrical, plumose. 
Neuter floret 1, rudimentary and very minute, coriaceous, 
sessile, often obsolete. — Named from ipappri, sand. 
1. P. arenaria Roem. et Sch. ( common S., Marram, or 
Mat-weed) ; panicle cylindrical acuminate, glumes acute, hairs 
three times thicker than the floret. P. littoralis Beauv. 
Arundo arenaria L. : E. B. t. 520. Ammophila arundinacea 
Host: Pam. Gr. t. 8. 
Sandy sea-shores, frequent. If.. 7. — Rhizome extensively creeping. 
Leaves long, narrow, rigid, involute, glaucous. Culms 2 — 3 ft. high. 
Glumellas far more rigid than the glumes; the larger one with a 
small sinus below the point. 
fyyj" Glumes 2. Styles short. Stigmas thick, oval or oblong, 
plumose. 
9. Milium Linn. Millet-grass. (Tab. VI. f. 8.) 
Panicle spreading. Spikelets somewhat dorsally compressed, 
awnless. Glumes 2, nearly equal, flattish, herbaceous, rather 
acute, scarcely longer than the floret. Glumellas 2, nearly 
equal, glabrous, ultimately hardening and enclosing the caryopsis. 
Neuter florets 0. — Named either from mille, a thousand, on 
account of its fertility ; or, according to Theis, from the Celtic 
mil , a stone, from the hardness of its fruit. 
1. M. eflfusum L. ( spreading M.) ; panicle glabrous its 
branches subverticillate, leaves lanceolate, ligule obtuse. E. 
B. t. 1106: Pam. Gr. t. 17. 
Moist shady woods. %. 5 — 6. — Culms 3 — 4 feet high. — We 
have above, for the sake of simplicity, given this genus a character 
very different from what it ought actually to have, and which would 
remove it to near Panicum and the tropical genus Paspalum : it has 
only one true glume, the lower being entirely absent, while what we 
have called the second glume is a neuter floret composed of one 
glumella as large as, and precisely similar to, the glume. 
10. Gastridium Beauv. Nit-grass. (Tab. VI. f. 9.) 
Panicle contracted, spike-like. Spikelets scarcely com- 
pressed. Glumes 2, acute, awnless, ventricose at the base, 
keeled upwards, membranous, much longer than the floret. 
Glumellas 2, membranous ; outer one truncate or toothed at 
the end with (or without) a long straight awn below the 
point. Neuter florets 0.— Named from yaorpdwv, a ventricle, 
or little swelling, as is seen at the base of the spikelet. 
1. G. lendigerum Gaud. ( owned N.); glumes lanceolate
