PANICU1M CI LIIFERUM IL sp.
Culms caespitose, 2-8 dm. tall, erect, at length much branched and decumbent, hirsute, except a naked ring below the barbed nodes, with ascending or nearly appressed hairs, which are usually more scanty at the summit or nearly wanting. Sheaths papillose hirsute with ascending or nearly appressed hairs, the basal ones crowded, the remainder shorter than the internodes ; ligule a ring of hairs about i mm. long, often with an upper supplemental row of much longer hairs ; leaves rough and pubescent on the lower surface with short rigid appressed hairs, at least at first, the upper surface smooth and glabrous, or sometimes a few scattered long hairs near the base, ciliate with ascending hairs, 9—I I-nerved, rounded at the base, acuminate at the apex, oblong-lanceolate to lanceolate, erect or ascending, those toward the base of the culm more and more spreading, shorter and broader, the primary leaves 2.5-9 cm. long, 3-12 mm. wide, those on the branches 6 cm. long or less, 2-5 mm. wide ; mature primary panicle broadly ovate, 7-9 cm. long, 6-40 cm. wide, the branches spreading or slightly as cending, the longer 5-6 cm. in length, the panicles on the branches much smaller and exceeded by the leaves, with the bases included ; spikelets obovate, somewhat acute, 3 mm. long,
the first scale glabrous, about one-half as long as the spikelet, 1-3-nerved, acute or obtuse, or sometimes 3-toothed, the second and third scales equal in length, 9-nerved, strongly pubescent with somewhat ascending hairs, the latter scale enclosing a hya line palet about one-half its length, the fourth scale chartaceous, oval, obtusely acute, enclosing a palet of equal length and similar texture.
Type collected by the writer in the " high pine land " at Eustis, Lake Co., Florida, March 12-31, 1894, no. 147. Nos. 27, 75, 79, 94, 96, 103, iii8, 1231, and 1518 of the same collection also belong here ; as well as no. 1857, collected in the same place in 1895, and well representing the late and much-branched state. The harsher papillose pubescence, the broader and shorter leaves, glabrous above, and the larger more open panicle readily separate this from P. malacon, which is described below.
I was at first inclined to consider this the P. ovate of Elliott, but after a careful comparison with the description and with a specimen so named by Elliott, I feel justified in the above disposi tion of it.
