3. T. bellespicata Rendle sp. nov. 



Cfespitose, shoots ascending, branched, pilose-hirsutulose, be- 

 coming glabrous above ; nodes densely hairy ; leaves linear, 

 tapering towards both ends, acute ; panicle dense, secund, 

 spikelets large, bearing long stiffish red shining hairs ; glume I. 

 minute ; gl. II. separated by a short internode fi-om the first, 

 lai-ge, coriaceous, folded along the stout hairy midrib, which is 

 prolonged into an awn equal to the length of the glume ; gl. III. 

 similar but narrowei- than the second, and with a longer awn, 

 including a shorter nai-row membranous pale with a (J flower ; 

 fertile gl. small, membranaceo-coriaceous convex, subtending a 

 similar but shorter pale and a $ flower. 



Perennial (?) from a slender rhizome; shoots 16 to 20 in. long. 

 Internodes slender, I line in diameter at the base of the shoot, 

 the lower ones short, haiiy, the uppei- elongated and glabrous 

 except below the nodes. Sheaths reddish, membranous, sti-iate, 

 lower ones exceeding the internodes and bearing numerous whitish 

 hairs often from a tubercled base ; upper becoming looser and 

 shorter than the internodes, subglabrous or glabrous ; ligule 

 represented by a line of short dense hairs ; blade flattened, 

 subrigid, generally 3^ to 5^ in. long by 1]- to 1'/ lines broad, 

 tuberculately pilose especially on the under face. Panicle 3^ to 

 4 in. long, branches ascending, secund, lowest about 1 in. long, 

 spikelets shortly stalked on the branches, or small lateral 

 branchlets. Pedicel bearing a small tuft of spreading hairs on 

 the swollen end. Spikelets about 2^^ lines long. Glume I. ^ line 

 long, coriaceous, scaphoid, the end truncate or rounded, enerved, 

 bearing a short tuft of hairs at its insertion; gl. II. about 2} lines 

 long, with a pair of well-marked lateral nerves, each half narrowly 

 suboblong, tapering above to a rounded tip which projects slightly 

 beyond the insertion of the awn, margin ciliolate, back and sides 

 bearing numerous stiffish rosy hairs, often from a tubercled base, 

 about equal to the length of the glume ; gl. III. with an awn 

 twice its length and tubercled hairs chiefly near the margin and 

 especially in the upper half, pale 1 ^ line long, glabrous, sharply 

 folded between the well-marked nerves ; sometimes two of the 

 three stamens are minute and apparently barren. Fertile gl. L\ 

 line long, glabrous, inconspicuously 5-nerved, with narrow oval- 

 oblong sides tapering towards the bluntish tip ; pale 1] Hue long. 



Near the Abyssinian 7'. longiseta Hochst., from which it is dis- 

 tinguished by habit, leaves with narrow base, and larger spikelets 

 with stronger pioportionately narrower second and thii-d barren
