140 XXVIII, GRAMINEZ. [ Rottheellia 
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, seaphoid, blunt; 
gis. ITI. 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, 2 in. in diameter at the base ; lowest sheath 
51 to 6 in. long, the median reaching 10 in. with a blade 18 in. 
long. Ligule like the rest of the plant glabrous, 5 to 3 line 
long. Inflorescence in stronger specimens 17 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 stiff upwardly directed points on the outer 
edge, hollow, plane of separation horizontal, } in. long below, 
decreasing to 4 or 5 lines above. Outer glume of sessile spikelet 
3 to 32 lines long, inner 23 lines long with a strong sparsely 
muriculate keel, incurved at the lateral nerves, gl. ITT. elliptical 
2-nerved, 21 lines long, pale very slightly shorter (I never saw a 
flower, but as the spikes were getting ripe there may have been a 
& flower which has perished), fertile glume 21 lines long, pale 
slightly shorter. Pedicel of stalked flower free, muriculate like 
the rhachis-joint, narrowly clavate, 13 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 11 line, spikelets 24 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. 
Puxco ANDONGO? No information was found with the plant, which 
however was in a bundle with others from Pungo. No. 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, subcompressed, dull purplish, glabrous; sessile 
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-
