5. C. Phoenix Rendle sp. nov. 
Perennial by a stout strong horizontal rhizome, widely cespitose, 
stems sturdy in the lower part, closely enveloped by the large, 
long, loose, somewhat sparsely hairy leaf-sheaths, or in the shoots 
which have shot forth after the forest fires, with a much shorter 
and not strongly developed lowest internode and sheath ; upper 
sheath cylindrical, closely enveloping and about 2 to 3 the length 
of the slender terete internode, glabrous except at the pilose 
mouth ; ligule conspicuous, red-brown, membranous ; blade long, 
linear-tapering, in the stronger leaves very narrowly linear- 
lanceolate, with an acuminate awnlike tip, rigidulous, sub- 
scabridulous ; panicle lax, effuse, about 6 in. long, branches long, 
slender, drooping, three or four together, bearing 1 to 4 lanceolate 
acuminate purplish spathes, pedicels } to 4 as long as the spathe, 
racemes subsessile, stalks epinastic, each with 2 basal pairs of 
homogamous spikelets and 2 to 3 § ; homogamous spikelets linear- 
faleate to lanceolate-acute, reddish, ¢, glabrous, rhachis-joints 
and pedicels with white villous margins; § spikelets exceeding 
the rhachis-joint, oval to oval-oblong, gl. I. ovate, 9-nerved, 
margins involute, carinate and scabridulous in the upper third ; 
gl. II. subequal, 3-nerved, broadly scaphoid, margins incurved at 
the lateral nerves, median nerve carinate and scabridulous in the 
upper half; gl. III. shorter, hyaline, 2-nerved; gl. IV. shorter, 
slender, hyaline, awn brown flexuose, 13 in. long ; gl. I. of pedicelled 
spikelet flattened, lanceolate-acute, reddish, glabrous, 7-nerved, 
apex aristate; gl. II. oval-oblong, 3-nerved; gl. III. shorter, 
hyaline, with an aborted ¢ flower at the base, or no trace of a 
flower ; gl. IV. absent. 
Plants 1} to 2 ft. high; basal sheaths in the strongly-grown 
specimen (No, 7193) 9 in. long, in the rest (No. 7226) not ex- 
ceeding 3 in.; upper sheaths 4 to 2 in. long ; leaf-blades reaching 
15 in. (or perhaps more) in length, by 2 to 5 lines broad. Ultimate 
spathes 1} to nearly 2 in. long; racemes 7 to 11 lines long, stalks 
pulviniform, shortly villous inside, the longer reaching 1 line; 
homogamous spikelets 3 to 4 lines, with glabrous back and margins 
carinate in the upper half, and scabridulous like the apex, rhachis- 
hairs shorter than the joint, which is a little over 1 line, inser-
