nESCRlPTIOX. 



Culms erect, rather slender, striate, glabrous, GO to 90 cm. high, 3 or 4-jointed; 

 basal leaves few, those of the cubns {] or 4; sheaths shorter than the internodes, 

 striate, sparsely hispidulous; li^aile very short, ciliate; blades green, rather soft, 

 flat or loosely involute, glabrous beneath, liirsutulous above, 10 to 20 cm. long, 3 to 

 6 mm. broad, acute at the apex; panicle very loose, Hexuous, somewhat drooi)ing, 

 10 to 20 cm. long; rays slender, solitary or rarely in twos, scabrous on the angles,' 

 pulvillate at base, the longest about half as long as the panicle, naked below the 

 middle; S])ikelets pale green or purpli.^h, loosely 3 or 4-nowered, 8 to 12 mm. long; 

 joints of the rachilla hirsute; glumes subulate, glabrous, each 1-nerved, the lower 

 about 3 mm., the upper 4 mm. long; lemma lanceolate, o-nerved, scabrous toward 

 the aj)ex, keeled half way or more, 6 to 8 mm. long, tipped with a more or less 

 flexuous awn 10 to 15 nmi. lung, altniptly narrowed at l)ase into a hispid tubular 

 structure eiuarcling the rachilla, which apparently disarticulates halfway between 

 the florets; palea lanceolate, as long as the lemma, the scabrous nerves uniting in the 



acuminate apex, the inflexed sides one-third as broad as the internerve (Pi.vte 

 XIII.) 



A very remarkable species, possessijig a form of lemma peculiar to itself. The 

 stipitate base of the lennna might better be considered a downward elongation of the 

 callus, surrounding and becoming grown to the rachilhi, which has likewise become 

 elongated so that the joint is still at the base of the callus. This coneej)tion makes 

 more apparent the relation of the plaiit to F. snbnlata. 



The following specimens belong to this much-confused species:
