Marca 27, 1915] Two HuxpreD Twenry Six New Srecies—I 2677 
nearly smooth or obscurely striate longitudinally, reclining 
and taking root from the lower joints, few to severally 
clustered from a perennial rvot base, the larger or stronger 
stems alternatingly branched up to the middle, the branches 
ascending, green and slender, the points of branching strongly 
enveloped by marcescent bracts, other joints nodulose; roots 
long, flexible, numerous. Leaves alternating, scattered along 
the whole length of the stems and their branchlets but 
usually above the middle, ascending or divaricate, soft mem- 
branous, equally light green on both sides in the fresh state, 
duller green when dry, the older ones subpersistent and 
straw brown, linear, gradually tapering to the sharply pointed 
apex from the middle of the blade, the base only slightly 
narrowed, varying from 4 to 6 mm wide below the mid- 
dle and 5 to 9 cm long, frequently much shorter and 
bract-like, flat or nearly so, very slightly roughened; mid- 
vein stramineus and rather prominent beneath below the 
middle, the 3 lateral veins of each one half quite evident 
beneath; sheaths one half to two thirds as long as the 
internode, smooth and membranous, ultimately widely sep- 
arating from the stem or branches, glabrous or only the 
edges ciliate, striate, ligule composed of a circle of hyaline 
hairs. Inflorescence terminal, erect or ascending or often 
recurved, the young panicles slender, the old ones broadly 
paniculate, 1.5 to 2.5 dm long, the larger ones nearly 1.5 
dm across, glabrous though very slightly scabrid, green or 
stramineus when old, all branches divaricate and making a 
lax panicle, the ultimate branchlets wand-like and very 
_slender; pedicels varying from 3 to 9 mm long, also wavy, 
appearing a trifle thicker at the distal ends; spikelets el- 
liptic, 1 to 1.25 mm long, 2-flowered; empty glumes per- 
sistent, enclosing the 2 florets, in anthesis widely spreading 
at the top; the lower one a trifle longer, the margins 
slightly thicker than the middle, obscurely 3'¿to 5-veined 
region, obtuse at both ends, the apical margin sparsely 
hyaline ciliate, otherwise glabrous, broadly elliptic; the up- 
per empty glume a trifle narrower, notched at the apex or 
occasionally in the old spikelets well parted, less ciliate at 
the apex, otherwise similar to the opposite one; flowering 
glume 1 mm long, broadly elliptic or rotund, subhyaline
