Digitaria .] CLVil. graminb^ (Stapf). 445 
internodes 1J-2J lin. long; pedicels 2-3-nate, finely filiform, sub- 
angular, more or less scaberulous, unequal, the longer about 1 lin. 
long. Spikelets loosely appressed, of successive pairs approximate 
or with a clear interval between the pairs, oblong to elliptic-oblong, 
acute to subacute, 1-lJ lin. long, obscurely silky. Lower glume a 
very delicate white cuff -like membrane, soon breaking up ; upper 
lanceolate, acute, equalling the spikelet or slightly shorter, 3-nerved 
with 4 lines of very fine appressed silky hairs. Lower floret : valve 
oblong, acute, equalling the spikelet, 7-nerved, nerves fine, prominent 
(except sometimes the outermost), with lines of usually appressed 
slightly wavy hairs between the inner side-nerves (of each half) and 
along the margins, hairs as fine as in D. eriantha, but with the obtuse 
tips slightly widened or towards the tip of the spikelet yellow and 
subcapitellate, J-J lin. long ; valvule and lodicules very minute. 
Upper floret oblong, shortly and acutely acuminate, equalling the 
spikelet, firmly chartaceous, brown.

14. D. eapitipila, Stapf: Perennial (base unknown). Culms 
slender, sheathed high up, glabrous. Leaf-sheaths (upper) tight, 
finely striate, glabrous and smooth or sparingly hairy upwards ; 
ligules very short, scarious, truncate, ciliolate ; blades erect, narrowly 
linear from an equally wide or slightly contracted base, long-tapering 
to a fine point, up to 5 in. by 1| lin., the uppermost much shorter 
and quite imperceptibly passing into the long (6-9 in.) sheath, 
flat with narrowly involute margins, rather firm, finely hairy on both 
sides, midrib and primary side-nerves hardly differentiated, some- 
what stout, very slightly prominent below. Racemes 5-8, sessile, 
scattered on a very slender upwards angular common axis (up to 
over 3 in. long), fastigiate, slender, loose, up to 6 in. long ; rhachis 
filiform, triquetrous, lin, wide, very finely marginate, slightly 
scaberulous, internodes up to 3 lin. long ; pedicels mostly 2-nate, 
unequal, the longer 1J lin. long, finely filiform, flexuous, angular, 
obscurely scaberulous with subdiscoid tips. Spikelets oblong, 
subacute, lj-lf lin. long, pale or brownish-green, dirty and fluffy- 
silky. Lower glume a short delicate hyaline truncate membrane, 
early breaking up, upper oblong, subacute, 1J-1J lin. long, thin, 
3-nerved, with dense lines of hairs between the nerves and along 
the margins, hairs very fine, up to J lin. long, exquisitely capitellate. 
Lower floret corresponding in outline and length to the spikelet : 
valve thin, flat, 7-nerved, with dense lines of hairs between the 
inner side-nerves and along the margins, hairs as in the upper glume, 
but shorter ; valvule truncate or 2-fid, up to J lin. long, lodicules 
half as long. Upper floret oblong, acute, turning dark brown,
