 Plian. V. 6 (1889) p. 667. Annual?; stems erect or ascending from a 

 creeping rootstock, 1-4 ft. higb, stout or slender, leafy, subterete, 

 simple or branched, smooth, polished, brown. Leaves 4-20 by j-5 in., 

 finely acuminate with setaceous tips, rigid, suberect, green, glabrous or 

 nearly so, margins scabrid ; sheaths slightly compressed, smooth ; 

 ligule reduced to a very narrow membrane. Panicle 1-2 ft. long, 

 occupying ^-k the stem, racemiform ; fascicles of racemes rather 

 distant, ou capillary flexuous peduncles |-3 in. long, subflabelliform or 

 subglobose, g-lj in. broad, sometimes reduced to a few spathes and 

 spikelets ; outer spathes Ioniser than the fascicles, 1-1| in. long, more 

 or less hairy with simple or bulbous-based hairs; proper spathes ^-\ in. 

 long, lanceolate, acute, compressed, glabrous or with some bulbous- 

 based hairs, margins scai'ious. Involncral ^pil-elets in contiguous super- 

 posed pairs reaching 3 in. long, green tinged with red ; lower invol.- 

 glume linear-lanceolate, acuminate, covered with long often bulbous-based 

 bristles, many-nerved ; upper invol.-glume oblong-lanceolate, acuminate, 

 1-nerved, ciliate above the middle, n)argins in flexed ; lower floral glume 

 as long, very narrowly linear, hyaline, 1-nerved. Lodicules cuneate. 

 Anthers -^ in. long. Pedicellate spilcelets like the involucral, but nearly 

 glabrous. Glumes 3 ; lower invol.-glume winged on one margin, nerve- 

 less, the other two as in the involucral spikelets. Bisexual spikelets 2, 

 sessile, -^ in. long, linear-oblong, obtuse; callus small, with a short 

 reddish beard ; lower invol.-glume scabrid, deeply channelled dorsally, 

 nerveless, tip hispid, narrowly truncate ; awn |-1 in. long. Anthistirla

Small annual or perennial grasses ; stems slender, compressed, many- 

 noded. Leaves linear from a usually rounded equilateral base; sheaths 

 compressed, keeled, shorter than the iuternodes. Panicle usually 

 occupying | the stem ; branches usually fascicled and interspersed 

 with scarious spathe-like bracts ; })roper spathes boat-shaped, acute, 

 compressed, more or less herbaceous on the back, many-nerved, with 

 scarious margins ; racemes fascicuhforra, solitary at the apex of the 

 stem and branches, articulate with the peduncle below the lowest 

 spikelets, at length all falling away from it. Spikelets dimorphous, the 

 4 lower whorled, male or neuter, forming an involucre round the in- 

 articulate rhachis. Involucral spilcelets pedicellate ; pedicels short, 

 flattened. Glumes 3 ; lower invol.-glume oblong-lanceolate, 3-5-nerved ; 

 upper invol.-glume similar, 3-nerved; floral glume hyaline, 1-nerved. 

 Lodicules cuneate, retuse. Anthers violet. Pedicellate spikelets on long 

 slender pedicels, similar to the involucral. Bisexual spikelets lanceolate 

 or linear-lanceolate ; lower invol.-glume truncate or shortly 2-fid at the
