ing their nests. One nest examined by members of our party, containing 
numerous eggs, consisted of a large mound made entirely of sand and this 
grass very closely packed. 
The species is manifestly allied to Jschaemum aristatum Linn., but differs 
in so many characters that it has been considered advisable to treat it as 
a distinct form. 
ISCHAEMUM PUBESCENS sp. nov. § Euischaemum. 
Species J. aristato affinis, differt foliis pilosis, spiculis paullo 
minoribus, glumis I spiculae sessilibus utrinque nodulis 2 obs- 
curis praeditis, dorso parce piloso. 
An erect perennial grass about 1 m high, the sheaths and 
leaves rather softly pilose with long white or pale hairs, the 
nodes rather densely ciliate-bearded, the internodes, under the 
sheaths, somewhat glaucous, about 3 mm in diameter. Leaves 
narrowly lanceolate, 10 to 18 cm long, 8 to 12 mm wide, acu- 
minate, base of the upper ones truncate, of the lower ones 
narrowed, margins scabrid, both surfaces softly pilose with 
scattered, long hairs; sheaths rather lax, pilose; ligule brown, 
cleft, somewhat pubescent, 2 to 3 mm long. Racemes binate, 
closely appressed, 8 to 10 cm long, long-exserted, rather promin- 
ently white-ciliate, the joints 3-angled, bearded on all angles, 4 
mm long. Sessile spikelets oblong, obtuse, about 5 mm long, 1.8 
mm wide, the callus bearded; first glume coriaceous, obtuse, mar- 
gins inflexed throughout, with two, broad, obscure undulations 
(scarcely nodules) near each side in the lower part, the back 
usually with very few, scattered, ciliate hairs; second glume 
lanceolate, acuminate, somewhat keeled, 5 mm long; third and 
fourth glumes hyaline, the fourth cleft to the middle, bearing in 
the cleft a geniculate, somewhat twisted, scabrid awn about 
13 mm long. Pedicellate spikelets dimidiate, 5 to 6 mm long, 
the pedicels stout, 2 mm long, bearded; first glume widely winged 
on one side, springly ciliate-pilose on the back, smooth, the 
wing obscurely denticulate.

Similar to Ischaemum aristatum Linn., and manifestly allied to that 
species. It is characterized, however, by its prominently pilose leaves and 
sheaths, its white-ciliate racemes, and the first glume of the sessile spikelets 
with very obscure marginal undulations which can scarcely be called 
nodules; the very short rachis-joints, and the bearded callus is also charac- 
teristic.
