Andropoyon] xxviii. gramixe/E. 149 



spikelets narrowly lanceolate-oval, glabrous except for a tuft of 

 .short white hah\s at the base of the acute callus, callus medianly 

 furrowed, outer glume lineax'-oblong with a strong median furrow 

 for fj of its length from the base, coriaceous becoming scarious at the 

 -•ipex, margin incurved membranaceous, slightly exceeding gl. II. 

 which is narrowly navicular, subacute with keel hispidulous on 

 the upper half; gl. III. shorter, hyaline, linear-oblong, blunt; 

 fertile glume linear-oblong, deeply bipartite, with a strong kneed 

 ;iwn springing from the notch, column deep-brown shortly hairy, 

 subula pale, scabridulous ; stalked spikelet exceeding the sessile, 

 dorsally flattened, lanceolate, outer glume with hispidulous 

 carinate margins, midrib conspicuous with 5 less conspicuous 

 nerves on each side, apex triaristulate ; gl. II. shorter, narrowly 

 oval, 5-nerved with incurved hyaline ciliate margins ; gl. 111. and 

 IV. shorter, equal. 



About 3 ft. high, culms not exceeding 1 line in diameter ; 

 leaf-sheaths 1 to If in. long, hgule leduced to a scarious 

 ridge less than ~ line long ; lowermost (linear) leaves to 6 in. 

 long by L^ line wide, upper (with cordate base) 2 to 4 in. long, 

 3 to 6 lines broad at the l)ase. Racemes 1}, in. and 1 in. respect- 

 ively, not including awns, approximate, rhachis-joint 31 lines, 

 including the glabrous cup (1^ line); sessile spikelet 4 to 4-} 

 lines, including the callus (1 line) ; gl. I. 4-nerved, greenish 

 becoming reddish at the apex ; gl. II. 3^ lines long, subcoriaceous, 

 glabrous ; gl. III. 2^^ lines, faintly 2-nerved with margins in- 

 curved ; fertile glume 2 y lines, awn 2 in. column slightly exceeding 

 subula. Pedicelled spikelet 8 lines, outer glume 5 to G lines long, 

 median aristula 1 to 2 lines, lateral ones very short; gl. II. 

 4:\ lines long ; gls. III. and IV. 3^ lines, the former 3-nerved 

 lanceolate, subhyaline, the latter hyaline, narrow, 1 -nerved. 



Near the South African A. aniplectens Nees, but differs in the 

 marked broadly cordate-based leaves, especially on the stronger 

 (flowering) shoot, the shorter few-flowered racemes, and the 

 longer and stronger awns of the sessile spikelets-.
