one-half its length, the fourth scale chartaceous, oval, enclosing a 

 palet of equal length and similar texture. 



Collected by the writer in the " high pine land " at Eustis, 

 Lake County, Florida, May 1-15, 1894, no. 628, and distributed 

 as P. paiiciflonun Ell. It appears quite distinct from a specimen of 

 that species, so named by Elliott, preserved in the herbarium of 

 Columbia University, the character of the pubescence and the 

 spikelets serving well to distinguish it. 



Panicum malacophyllum n. sp. 



Whole plant, except the leaves, papillose-hirsute with rather 

 soft long spreading hairs. Culms 4 dm. tall or less, erect, at 

 length branching toward the summit ; nodes densely barbed with 

 reflexed hairs ; ligule a ring of hairs about I mm. long ; sheaths 

 shorter than the internodes, loosely embracing the culms; leaves 

 erect or ascending, narrowly oblong-lanceolate, narrowed toward 

 the rounded base, acuminate at the apex, softly pubescent on both 

 surfaces, rough on the margins, 7-nerved, the primary leaves 5-8 

 cm. long, 4-1 1 mm. wide, the leaves of the branches 4 cm. long 

 or less, 3-5 mm. wide; panicle slightly ex.serted, ovate, 3-5 cm. 

 long, the branches spreading, somewhat flexuous, the lower 1.5-2 

 cm. long, bearing 4-8 spikelets on pedicels shorter than them- 

 selves ; spikelets obovate, 3-3.5 mm. long, acute, the outer three 

 scales membranous, densely pubescent with long spreading hairs, 

 the first scale orbicular-ovate, acute, about two-fifths as long as 

 the spikelet, i-nerved,the second and third .scales equal in length, 

 broadly oval, 9-nerved, acute, the latter enclosing a hyaline palet 

 about one-half its length, the fourth scale chartaceous, broadly 

 oval, yellowish white, enclosing a palet of equal length and similar 

 texture. 



Type collected by Mr. B. F. Bush on May 19, 1895, at 

 Sapulpa, Indian Territory, no. 1228. The grass secured by Dr. 

 Edward Palmer in 1868, on the False Washita, between Fort 

 Cobb and Fort Arbuckle, Indian Territory, no. 383, belongs here. 

 Dr. Gattinger also obtained it in the cedar barrens of Tennessee, 

 in May, 1880. 



This appears to be sufficiently distinct from P. Scribnenamun 

 to warrant giving it specific rank. Its more slender habit, the 

 long hirsute pubescence of the culm and the panicle, including its 

 branches and pedicels, the densely barbed nodes, the softly pubes- 

 cent leaves, and the somewhat smaller acute spikelets which arc 

 densely pubescent with hirsute hairs, appear to make the above 

 disposition of the plant necessary. In P. Scnbnerianum the pu-
