A slender species, 2 feet high, with narrow, flat, scabrous foliage. Panicle 8-5 inches long, contracted; 
branches short, whorled. Spikelets green, erect. Glumes equal, acute, with one broad, green nerve. Flower very

Gen. XIII. ECHINOPOGON, Beauv. 
Spicule uniflore, setula villosa accedente, coarctate. Glume swequales, flore equilonge. Palee 2, 
eguilongee; inferior basi villosa, apice bifida, longe aristata; superiore bicarinata, apice bidentata; arista 
terminalis, haud torta. Stamina 3. Ovarium barbatum.—Gramen scaberulum ; folis planis; panicula 
spiceformi v. capituliformi. 
The only known species is a very common extratropical Australian, Tasmanian, and New Zealand, harsh, sca- 
brid Grass, differing from Agrostis in habit, capitate inflorescence, and terminal awn.—Spikelets crowded into an 
ovate or globose head, bristling with rigid, spreading awns. Glumes equal, acuminate, rigid, as long as the solitary 
flower, which has a silky tuft of hairs at the base. .Palee nearly equal; the lower with a bifid top, and rigid, not 
twisted awn; upper with a small, stiff, villous bristle at its base. Stamens three. Ovary bearded at the top. 
(Name from exıvos, a prickle, and rwywv, a beard.)

Disrris. Australia, New Zealand, and Norfolk Island. 
A rough, scabrid, harsh Grass, growing in small tufts, common in extratropical Australia and New Zealand.— 
Culms 6 inches to 2 feet high, leafy below. Sheaths of upper leaves long; ligula short; lamina flat. Panicle 
contracted into a cylindrical, blunt, short or long (4-14 inch long) head, conspicuous from the spreading, stiff, 
scabrid awns. Spikelets shortly pedicellate. 
Oss. I know nothing of E. Gunnianus, Nees (Lond. Journ. Bot. ii. 413), which is described as having the 
habit of 4grostis alba ! and as having been picked out of Gunn’s specimens of Agrostis parviflora (n. 1011). 
Gen. XIV. POLYPOGON, Desf. 
Glume 9, subequales, carinate, aristate, 1-flore, flore multo longiores. Palee 2; inferiore apice 
truncata, emarginata, mutica v. sub apice aristata; arista haud tortili; superiore bicarinata. Sguamule 2, 
subfalcatee, ovarium superantes. Caryopsis intra paleas libera. — Folia plana; panicule ramosissima, 
sepius contracte, spicaformes ; spicule pedicello continue. 
Very elegant, often sea-side Grasses, conspicuous for the white awns on the pale, silky, contracted panicles. 
There are but few species, and these scattered over various temperate and tropical regions.—Glumes longer than 
the solitary flower, nearly equal, keeled, awned, one-flowered. Palee two; lower abruptly notched at the tip, 
awnless, or with an awn below the tip; upper two-nerved. Scales two, longer than the ovary. Seed free, but 
included within the pales. (Name from voAv, many, and oyov, a beard.)
