tige: the other sessile, with the lower flower neutral and of a sin¬ 
gle palea ; the upper perfect and fertile, of 2 thin and hyaline pa- 
lese shorter than the herbaceous or chartaceous glumes, the lower 
. awned from the tip. Stamens 1-3. Grain free. — Coarse and 
rigid perennial Grasses, with lateral or terminal spikes commonly 
clustered or digitate, the rachis hairy or plumose-bearded. (Name 
composed of avrjp , man , and rruyaiv, beard.) 
* Sterile spikelet staminate (stamens 3), aumless : spikes digitate. 
1. A. fiircsttus, Muhl. Culms (4° high) and leaves nearly 
smooth, bearing 3-5 straight and rather rigid hairy spikes together at 
the naked summit (or fewer on lateral branches); spikelets approx¬ 
imated, roughish-downy; awn bent. — Sterile soil, common. Sept. 
* * Sterile spikelet neutral, its lower glume awned : spikes simple. 
2. A. SCOparillS, Michx. Culms slender (2°-4° high), with 
many paniculate branches; the lower sheaths and narrow leaves 
hairy; spikes terminating the branches, peduncled, very loose, slen¬ 
der (2' long, often purple), the zigzag rachis hairy along the edges; 
pairs of spikelets rather distant, the sterile small, on a very hairy ped¬ 
icel; the fertile 3-androus, bearing a twisted awn. — Sterile soil. Aug. 
* * * Sterile spikelet abortive , reduced to a mere awn-like plumose ped¬ 
icel ; the fertile 1 -androus, straight-awned : spikes clustered , lateral 
and terminal , often partly inclosed in the fattened bract-like sheaths ; 
the slender rachis clothed with copious long silky (white) hairs. 
3. A. Virglnieus, L. Culm flattish below, sparingly short- 
branched above (3P high); sheaths smooth; spikes 2-3 together in dis¬ 
tant oppressed clusters (1/ long). — Sandy soil, southward. Sept. 
4. A. macroiinis, Michx. Culm stout (2° - 3? high), bushy 
branched at the summit , loaded with numerous spikes in dense leafy 
clusters; sheaths rough, the upper hairy. — Low grounds, southward 
near the coast. September. 
59. SORGHUM, Pers. Broom-Corn. 
Spikelets 2-3 together on the ramifications of an open panicle, 
the lateral ones sterile or often reduced merely to their pedicels ; 
the middle or terminal one only fertile, its glumes coriaceous or 
indurated, sometimes awnless : otherwise as in Andropogon. Sta¬ 
mens 3. (The Asiatic name of a cultivated species.) 
X. S. nutans. (Indian Grass. Wood-Grass.) Culm simple (3=

panicle narrowly oblong, rather crowded (6'-12' long); 'he perfect 
spikelets at length drooping (light russet-brown an s ,ni "8 ’
