nerved below and awned between the divisions of the deeply bifid 

 apex; awn seven to ten lines lonj^, slij^htly twisted, the column 

 not projecting beyond the outer j^lumes. Palea lanceolate, two- 

 thirds as lonic as its illume. Lodicules more or less ciliate. F'irst 

 ^iume of the pedicellate spikelet pilose aloni( the marj^ins, with 

 hairs similar to those at the base. — Valley of the Hiwassee (A.

Plate I. Figure 4. 



Culms stout, six to ten feet high, silky-villous near very hairy 

 and bearded panicle; nodes bearded with soft appressed hairs. 

 Sheaths shorter than the internodes, smooth, bearded at the 

 throat; ligule irregular, about one line long, finely ciliate, auri- 

 cled; leaf- blade one to two feet long (the uppermost shorter,) four 

 to twelve lines wide, hairy near the base, margins scabrous, with 

 long, slender tips. Panicle six to ten inches long, ovate-lanceolate, 

 or oblong, the joints of the racemes shorter than the sessile spike- 

 lets, ciliate with long hairs, as are the pedicels of the i^rimary 

 ^pikelets. Sessile spikelet three to three and one-half lines long, 

 one-fourth to one half shorter than the copious hairs at the base; 

 first glume broadly lanceolate, seven-nerved, two-keeled, thinly 

 hairy in the back and margins, shortly two-toothed at the apex; 

 second glume as long as the first, acuminate pointed, hairy on the 

 back and ciliate on the hyaline infolded margins above, three to 

 -five-nerved; third glume hyaline, a little shorter than the outer 

 ones, ciliate on the margins, usually three-nerved at the base, 

 acute or sometimes awned from the apex; fourth glume shorter 

 than the third, three-nerved at the base, ciliate on the margins, 

 deeply cleft and awned from between the divisions; awn six to 

 seven lines long, twisted, the column projecting beyond the outer 

 glumes. Palea one half as long as its glume, fringed at the apex. 

 Lodicules truncate smooth. Stamens two, about one line long. — 

 Specimens collected in the Hiwassee Valley by Prof. A. Ruth have 

 the third glume long-awned, similar to the fourth. This is the 

 only locality at present known within the State. 



4. Erianthus alopecuroiles Ell. Plume grass. 



Plate II. Figure 5. 



An erect grass, with stout, leafy stems three to ten feet high, 

 Avith rather densely flowered, woolly panicles five to ten inches 

 long. Culms round or slightly flattened near the base, densely 

 villous below the panicle and usually with a dense ring of erect 

 hairs at the nodes, at least the upper ones. Sheaths pilose above 

 and usually densely villous at the summit, with appressed hairs 

 and bearded at the throat; ligule one to two lines long, ciliate; 

 leaf-blade six to twenty-four inches long, tapering towards the 

 base and long acuminate pointed, surface smooth or thinly hairy, 

 margins scabrous. Spikelets about two lines long, less than half 

 the length of the copious ring of hairs at the base. Pedicels of 

 the primary spikelets half the length of the sessile spikelet, this a 

 little e>;ceeding the sparingly pilose joints of the raceme. Sessile
