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

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

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

 racemo composito ramis 1-3-nis oligostacliyis, 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 Ceratochloe, 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 nudisscabro-puberulis, spiculis oblongis bi-trifloris, glumis ina?qualibus obtusius- 

 culis, superiori flosculos subaequante, valvula inferiori flosculorutn perfectorum apice 

 brevi spatio membranaceo-appendiculata 7-nervi, flosculo 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. I. 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, gTeenish 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 we 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 are shorter than the internodes.
