Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1882 edition. Excerpt: ...obtuse, less than a line long. Santa Cruz Valley, near Tucson. (No. 464.) The habit of this grass is well marked, and it may prove a good species. The spikelets are exactly like those of No. 817 of E. Hall's Texan plants, referred to P. proliferum'JoxA it differs much from that in its low, branched habit, pilose sheaths, short and rather broad leaves--characters which point to P. capillare, L., to which it is doubtfully referred. The habit of the panicle is more like P. proliferum, while the prominently 3-5-nerved, pointed, lower glume and the palea to the third glume are characters not found in Eastern specimens of either P. capillare or P. proliferum, but point to P. virgatum, L. The third glume of th'e latter, however, is staminate and the fertile flower is more turgid. 6. Panicum fuscum, Swartz.--Santa Cruz Valley, near Tucson. June. Apparently the same as No. 825 of E. Hall's Texan plants, but more slender, with leaves and sheaths smoother. It is probably the P. reticulatum, Torr. (Marcy's Rept.) 7. Panicum ( Virgaria) sp., allied to P. fuscum, Sw.--Culms prostrate below, rooting at the lower joints, smooth, as are the numerous ascending branches, except just below the panicle; sheaths striate, smooth, slightly inflated, snorter than the internodes; leaves linear, cordate and clasping at the base (1---5 in. long, 3 lines wide), scabrous on the cartilaginous margin, which is also pilose near the base. Panicle at length exserted, 3-6 in. long, the axis and the ascending or erect simple branches finely pubescent, and also sparsely pilose with rather stiff, spreading hairs; the lower branches about 2 in. long, bearing the approximate but not crowded, racemose spikelets in pairs (the upper ones single), one nearly sessile and often imperfectly...show more
