panicle: spikelets 2-2} lines long; empty glumes lanceolate, sub- 
equal, 3-nerved, with abruptly acuminate hyaline tips; flowering 
glume, including the short conical and curved callus, 14 lines long, 
obliquely truncate at the broad apex, and pilose all over with ap-

MuuLenzBerGia Seatont, Scribner, n. sp. Panicle diffuse, the 
upper branches widely spreading; flowering glume four times as long 
as the obtuse empty glumes, bifid at apex, the divisions setiform ; awn

inches high (including the panicle): leaves linear-filiform, 2-3 inches 
long ; ligule prominent, hyaline : panicle nearly one half the length of 
the culm, the lower branches ascending, partly included in the upper 
leaf-sheath ; ; pedicels long and capillary, much exceeding the spike- 
lets: spikelets about 2 lines long; empty glumes small (} line),

Trin., but quite distinct. 
AGRostTis verticILLATA, Vill. Delf. 74; Trin. Unif. 195; Trin. 
Icon. 36. Kunth (Enum. Pl. I. 219) refers this to A. stolonifera, L. 
but there is some confusion in regard to the Linnean plant. Menke 
in his “ Catalogue of the Grasses in the Herbarium of Linneus,” says, 
under A. stolonifera, that “the Herbarium contains one of the forms 
of A. vulgaris which is called stolonifera, the Florin grass; another 
marked stolonifera by Linneus is A. verticillata, Vill.” — Mt. Ori- 
zaba, 10,000 ft., August (no. 192).
