This has several nine inch lonj^ leaves, like ajperua leaves, turnlnsr red when dvy ; 

 the.culms rise iVo n the centre of the leaves, a i'out and a half hiijh, with swellin"- ioints ; 

 lu'.ving three leaves, emhraciny the stem at each joint; from liie axils of these leawn 

 risesinall pedicels bearni*:^ two spiked panicles, standing like a pair of horns, fnll of 

 !og soft iiair, softer than cotton. Sloane. Browne says this plant was freipient in the 

 jiarish of St. Elizabeth, with a slender stem, and the llowers placed in distant tufts, on 

 long hairy footstalks ; the caljrine glumes also hairy, t-jcniinating in long bristles.

Spikes of the ])anicle conjugate; peduncles branching very much; rachis 

 woolly; awn cadacous.; male floscKJe wanting. 



Culm three to six feet liigh, upright, simple, round, smooth; leaves serrate ; pa- 

 nicle fastigi^ite, afoot long, loose, but not diffused; peduncles numerous, Iruni the 

 terminating sheaths of the cnim, upright, branched, sub-divided; jiediccls filiform, 

 iong, irj>i-ight. Spicules small, terminating, hairy, whitish, s(5litary or twin ; floscules 

 awnless, concealed by viUose hairs; hermaphrodite, sub-sessile, with one or two males 

 by the side of it ; these are pedicelled, and much smaller. It is calledy().r-/(7//^/(7.M. 

 Sw. Browne calls it mountain grass, who says the peduncles are covered with a long 

 vfhite down, and the spikeiets, which rise by pairs on long erect supporters, meet in a. 

 kiuti of umbel at tlie top.

'Gramen avenaceum, pankula minus sparsa, glumis alba seritea la- 

 nugine oliductis Sloaiie, v. 1, p. 43, t. 14, f. 2. Avenaceum as- 

 siirgens, panicula la.ia lanuginosa. Browne, p. 365. 



Panicle loose, smooth^ floscules double, awnless ; one pedicel shorter; calyxes 

 woolly. 



This has a thin contracted panicle, a three-glumed calyx, and the wool of the calyx 

 pressed close. Swartz ihmks the conformity of the valves, and the absence of the awn, 

 remove this species trom the androp'ogons. The male flowers also are frequently want- 

 ing. It may be the same as panicuin lanatum See Panic Grass. Sloane describes it 

 as follows : The uppermost joint had a sis inches iong leaf, cniLracing the culm ; this 

 joint was a foot long. The panicle was four inches long, not very sparse, composed 

 of many spikes, growing from the top of the culm without order ; each peduncle had 

 fixed to it, bv short footstalks, several reddish oblong seeds, lying between the chaffy 

 glumes, wnich are covered with a silky cotton. Browne calls it sour grass, and says 

 " The roots and leaves of tl*iS plant, pounded and applied externally, are observed to 

 cure sores and ulcers of all sorts, with more certainty than most other things used for
