OF THE PERUYIAN ANDES. 63

Bromus H^^vkeakus, Fresh Chicla, and in the npper vallev 

 of the Eimac ! I feel uncertain wlietber this sLonld be kept 

 distinct from 13. unioJoidcs^ H. B. K., wliich has a very wide 

 range in South America. 



Bromus let^is, Presl? Found in the upper valley of the 

 Eimac and at Chicla, the specimens varying much in size and ap- 

 pearance ! I have not seen authentic specimens of Presl's plant, 

 but mine agree fairly well with his description. By a j^rinter's 

 blunder the species appears as JB, tenuis^ Presl, in Steudel's Synop- 

 sis. Xo. 1370 of Mandon's ' Plants of Bolivia ' agrees closely "with 

 my specimens from Peru. It has been placed in Kew Herbarium 

 in the same cover with_B. aicleticus, Triu.,but cannot, I think, be 

 united to that species. 



Bromus frigidus, n. sp. Above Casapalta ! 



Cnlmis subsolitariis, tennibus, 9-15-pollicaribus, erectis, laevi- 

 bus ; foliorum vaginis striatulis, dimidiam culmi altitudinem vix 

 attiugentibus, liaibo brevi, piano, pra?sertim margine piloso ; 

 ligula lacera ; paniculee depanperatae secunda) ramis pubescenti- 

 bus, spiculam nutantem 3-6-floram gcrentibus ; glumis vacuis 

 insequalibus, superiori c^uam inferior sesquilongiori; gluma fertili 

 ovato-lanceolata, acuminata, tenuiter quiquenervia, puberula, 

 apice bidentata, sub apice aristata, arista dimidiam glumae 

 longitudinem attingente ; palea bicarinata, carinis ciliatis. 



This is allied to an undcscribed Andean Bi^omus — No. 13G8 of 

 Mandon's ' Plants of Bolivia' — but cannot, I think, be united with 



it. In Mandon's specimens the flowering glume is elliptical, 

 almost truncate at the summit, the teeth scarcely perceptible, and 



the awn decidedly shorter. The nerves of the flowering glume 

 are salient in his plant, while in ours they are very feeble.
