9. H. PUBIFLORUM Hook. f. Wild-barley. 



Culm to 25 cm., inclined at base, glabrous. Radical leaves 5 cm. long, 

 involute ; cauline leaves with long tumid striate sheaths, blades very 

 short and subulate. Spikes 3-4 cm. long, tawny-purplish. Glumes all 

 setaceous, hairy, scabrid above, 15 mm. long. 



Its smaller size and purplish spikes with hairy glumes, distinguish it
