Anadelfhia.] clvii. graminea; (Stapf). 395 
tips, showing a small circular scar. Racemes laterally shortly ex- 
serted, extremely fragile, up to 10 lin. long, consisting of up to 5 
sessile and 6 pedicelled spikelets ; joints filiform, the lowest rather 
stout, up to 5 lin. (normally ?), the others more slender, shortly 
densely and equally ciliate along the sides, tips truncate with a 
circular rim ; pedicels similar to the adjacent joints, but the lower 
at least usually shorter. Sessile spikelets lanceolate, including the 
very short obtuse and minutely bearded callus 2 lin. or the lowest 
(normally ?) up to 4 lin. long, pubescent. Glumes equal ; lower 
minutely 2-dentate or 2-mucronate, convex on the back, more or 
less pubescent, sometimes at length glabrescent, chartaceous, 
7- or upwards 9-nerved, faint, sides involute, shortly keeled towards 
the tips, keels scaberulous ; upper thinner, minutely emarginate or 
almost entire, with a fine bristle from the apex, loosely pubescent, 
ciliolate, 3-nerved, finely keeled upwards, keels scaberulous. Lower 
floret reduced to an oblong obtuse hyaline obscurely 2-nerved 
ciliate valve. Upper floret Q : valve oblong, 1J lin. long, 2-fid 
almost to the middle, very firm below, with the exception of the 
hyaline margins, 1-nerved ; awn up to over 10 lin. long, kneed at 
and twisted below the middle, minutely white-ciliate, column almost 
black, bristle straw-coloured ; valvule 0. Anthers 1 J lin. long. Pedi- 
celled spikelet similar to the sessile, the lowest not over 3 lin. long ; 
lower glume 9-1 1-nerved, upper very acute, without a mucro, 
5-7-nerved ; valves as in the sessile spikelet, but the lower 3-nerved 
and the upper hyaline, acute, entire and awnless.

All the material available (about a dozen pieces) is in an abnormal condition 
(prolification probably due to insect action). The replacement of the outer- 
most simple rays of many tiers by contracted leafy branches is certainly an 
anomalous feature. On the other hand it is doubtful how far the elongation 
of the simple rays and the basal joints of the raceme and the enlargement of the 
lowest sessile spikelets are due to the same cause, although they seem to be 
affected. The spikelets described above are otherwise to all appearance 
normal, and by themselves are sufficient to characterize the species as distinct 
from the remainder of the genus. 
6. A. hamata, Staff. Perennial (?). Culms (only the upper 
parts known) slender, terete, glabrous and smooth, internodes long- 
exserted. Leaf-sheaths terete, somewhat tight, glabrous or pubescent 
towards the mouth, smooth : ligules truncate, up to J lin. long ; 
blades linear, tapering to a fine point, flat, up to 1 lin. wide, dull 
green, flaccid, softly hairy all over, midrib and nerves very fine, 
the latter numerous and raised above. Spatheate panicle made up 
of few distant flowering branches, the lowest undivided at the base, 
4-6 in. long, filiform and flexuous, 2-noded, 1 -rayed from the lower 
node or like the following forming 2-4-rayed tiers ; all the rays simple, 
very unequal, of the lowest tiers up to 2| in., of the upper f~lj in. 
long ; subtending leaves like the preceding ones with well developed
