Dr. SmithV Obfervatiom on the Britijh Species of Bromus. 30 1 



fcabra, hinc canaliculato-comprefsa. Spicule 6 vel 7, alterna?, 

 feffiles, fecundse, non divaricatae, lineari-lanceolatas, luteolo- 

 virides plerumque pubcfcentes. Gluma cafycince inaequales, lan- 

 ceolate, brevius ariftatae, nervofas, apicem versus hirtas. Flofculi 

 6ado,imbricati, demiim patentiufculi, fubcylindrici, apicem versus 

 praecipue nervofi atque hirti. Arijla terminalis, glumis plerum- 

 que longior, fubnlata, fcabra. Gluma interior linearis, retufa, 

 fetis ere&is rigidis ciliata. 



The inner glume being ftrongly pectinated in this grafs and the 

 following one, feems to me a fure indication of their being Bromi, and 

 that any thing to the contrary in the infertion of the arijla^ being 

 in many fpecies very difficult to determine, and in fome variable, 

 is of lefs real moment. In habit alfo thefe plants agree with other 

 Bromi rather than with Feftuca, except indeed their perennial roots.
