Gen. Char. Spicidce multiflora?, rhachilla articulata. Ghana 2, membranacese, obscure 1-3-nerves, flosculis 

 breviores. Flosculi eallo truncato inserti, omnes perfecti : valvula inferior chartaceo-rigida, plurinervis, 

 apice membranacea, bifida, lobis prasmorso-dentatis, inter lobos setigera seta recta ; superior plano-com- 

 plicata lateribus in medio dentato-laceris apicera versus serratis ; apice emarginato. Lodiculce truncata?., 

 connate. Stamina 3, (antheris violaceis.) Ovarium oblongo-lineare, glabrum ; sl.tjli breves, discreti ; 

 stigmata parva, plumulosa. — Inflorescentia : racemus simplex, secundus. Gramina mollia. Folia brevia. 

 Spicuke bromoidece, oblong o-lineares, speciosca. Locus inter Poas Glyceriseas juxta Glyceriam, cui medi- 

 ante Glyceria (Windsoria) pallida consiliatur. Forsan hac W. pallida, amplificato generis nostri

1. Bromus carinatas; annuus, caule erecto, foliis linearibus pilosis vaginis deflexo-pilosis, 

 racemo cotnposito ramis 1-3-nis oligostachyis, spiculis sessilibus lanceolatis valde com- 

 pressis, glumis lanceolatis acutissimis muticis 3-5-nerviis carinatis, flosculis patulis, glu- 

 mella exteriore pubescente lanceolata ex apice bifido longe setigera carinata obscure 7- 

 striata, interiore bicarinata ad carinas ciliata, caryopsi hinc canaliculata. 



Perhaps this ought to be referred to the Genus CeratocJdoe, but the straight seta, or awn, is almost as 

 long as the floret, and, with the exception of the compressed spikelet, the character is entirely that of Bromus. 



1. Melica imperforata; panicula composita et decomposita (ante anthesin contracta), 

 pedicellis nudis scabro-puberulis, spiculis oblongis bi-trifloris, glumis inaequalibus obtusius- 

 culis, superiori flosculos subaequante, valvula inferiori flosculorum perfectorum apice 

 brevi spatio membranaceo-appendiculata 7-nervi, floscnlo supremo sterili sublineari 

 antheriformi, foliis anguste linearibus vaginisque scabris. Nees. — Trin. Gram. Ic. t. 355. 



— Melica colpodioides. Nees v. Esenb. in Tayl. Ann. of Nat. Hist. v. 1. p. 283 Poa 



viridi-purpurea. Hook, et Am. mss. 



This has certainly not exactly the habit of a Poa, to which we had been disposed to refer it ; and the 

 flowers are fewer in number than usually occur in that Genus. In appearance it approaches slightly to 

 Eragrostis Koenigii, and E. interrupta, but it unquestionably is not a species of Eragrostis. The glumes 

 are membranaceous, but the florets are of a firm texture, greenish and tinged with purple, their margins white 

 and membranaceous. We have only seen the upper portion of the plant, although the specimens are about 

 two feet in length ; the panicle is from 9 inches to a foot long. We adopt the Genus to which wc find that 

 Trinius, and since, Nees von Esenbeck, have referred it. 



1. Poa serotina, Gaud. — Poa fertilis, Host, Gram. 3. t. 14. 



Our plant resembles that of Gaudin in the spikelet, but it is more rigid, and the inflorescence is an inter 

 rupted, contracted, narrow, linear, erect panicle, the lower branches of which arc shorter than the intcrnodes. 



1. Stipa avenacea, L.
