140 XXVIII. GRAMINE/E. [liotthcdlia 



furrow, coriaceous, lanceolate, acuminate, almost shortly aristate, 

 ■with a flattened or slightly-rounded inconspicuously^ 5-nerved 

 back and short incurved edges bearing short sharp murications 

 diminishing upwards ; inner glume chartaceous, scaphoid, blunt ; 

 gls. III. and IV. hyaline, the former with a subequal pale, the 

 latter similar to and enclosed by the inner barren glume, sub- 

 tending a slightly shorter pale and ? flower. 



Culms 4 ft. high, \ in. in diameter at the base ; lowest sheath 

 5^ to 6 in. long, the median reaching 10 in. with a blade 18 in. 

 long. Ligule like the rest of the plant glabrous, H to ^ line 

 long. Inflorescence in stronger specimens 1 7 in. long from the 

 first branch ; common axis 8^ in. strong, terete ; lowest spike 

 .solitary 16 in. (broken at the top) including a stalk of 7 in., the 

 upper sessile, shorter (uppermost 8 in.), separated by decreasing 

 internodes. Rhachis-joints slender becoming clavate at the top, 

 with a line of short stift' upwardly directed points on the outer 

 edge, hollow, plane of separation horizontal, 'i in. long below, 

 decreasing to 4 or 5 lines above. Outer glume of sessile spikelet 

 3 to 31 lines long, inner 2^ lines long wdth a strong sparsely 

 muriculate keel, incurved at the lateral nerves, gl. III. elliptical 

 2-nerved, 2,\ lines long, pale very slightly shorter (I never saw a 

 flower, but as the spikes were getting ripe there may have been a 

 cJ flower which has perished), fertile glume 2?j lines long, pale 

 sHghtly shorter. Pedicel of stalked flowei' free, muriculate like 

 the rhachis- joint, narrowly clavate, 1^- to 2 lines long, spikelet 

 similar and subequal to the sessile, or slightly smaller. A 

 smaller inflorescence (11 in, long) on the second specimen has 

 rhachis-joints 3 lines long, pedicels li line, spikelets 2^ lines, and 

 parts smaller in proportion ; occasionally the pedicelled spikelet 

 is reduced in size and sterile. 



A very distinct species of the section, nearest R. latifolia Steud. 

 in the form of its inflorescence, which however is at once dis- 

 tinguished by its slender rhachis-joints, almost aristate muricate 

 glumes, etc. 



PuxGo Anduxgo ? Xo information was found with the plant, which 

 however was in a bundle with others from Pungo. Xo. 2849. 



3, R. huillensis Rendle sp. nov. 



Apparently perennial from a hard woody slender rhizome ; 

 culm erect from a short ascending base clothed with the strawlike 

 remains of sheaths in the axils of which are leaf-buds ; cauline 

 sheaths 2, compressed, the lower subcarinate, striate, margins 

 pilose ; ligule membranous, shortly truncate with very shortly 

 fimbriate margin ; blades short, narrowly lance-shaped, blunt ; 

 racemes few on an elongated axis which they exceed in length, 

 stalked, dense, subcom pressed, dull purplish, glabrous; sessih^ 

 and pedicelled spikelets 1 -flowered similar, the latter slightly 

 smaller; the former narrowly bluntly ovate about equal to the 

 rhachis-joint, callus very short, outer glume with a flat incon-
