13. S. Thollonii A $Zap/. Perennial, compactly caespitose ; rhizomes 
branched and densely covered with the remains of the cataphylls ; 
innovations extra vaginal, numerous, closely tufted with the culms. 
Culms including the inflorescence about 2-3 ft. high, more or less 
compressed, about 2-3-noded below the panicle, with the internodes 
exserted, glabrous, smooth, branched from about the middle ; 
branches forming a narrow, very lax inflorescence. Leaf -sheaths 
glabrous, compressed, keeled, the lower long-persistent, pale reddish 
or brown ; ligules short, truncate, membranous ; blades linear, 
acute, folded or flat, of the innovations up to over \ ft. long and Fi- 
lin. wide (flattened out), loosely hairy towards the base, otherwise 
like the short culm-blades glabrous, finely scaberulous on the sides, 
reddish or somewhat glabrescent, midrib very slender, nerves nume- 
rous, fine. Inflorescence up to 1 ft. long, of distant simple branches, 
geminate from the intermediate nodes, solitary towards both ends, 
filiform, unequal, when paired of 2 internodes ; spathe filiform, acute, 
lj-lf in. long, glabrous ; peduncles at length long-exserted from 
the spathe, erect, rarely flexuous, filiform, slightly thickened 
upwards, tip with a small oblique crenulate appendage, sometimes 
with a few hairs below it. Racemes 1-1J in. long, slender, villous, 
8-9- jointed ; joints cuneate from a subfiliform base, 2-2 J lin. long, 
with a short urceolate obtusely dentate or crenulate appendage, 
hairy on the back and long-ciliate on both sides from the base up- 
wards, the uppermost hairs up to 2 lin. long ; pedicels similar but 
much more slender and somewhat shorter. Sessile spikelets linear- 
lanceolate, acutely acuminate, 2-2J lin. long, including the shortly 
bearded callus. Glumes subequal; lower very minutely truncate 
or 2-dent ate, almost membranous, flat on the back, more or less 
white hairy along the middle up to half the length of the glume, 
inflexed margins very narrow, keels obscurely scaberulous, intra- 
carinal nerves 4-5, slightly raised ; upper glume somewhat shorter, 
broadly rounded on the back, linear-oblong, acute, 3-nerved,
