These are more or less closely gregarious, rather fragile and at first 
furnished with a distinct and usually naked apical papilla or 
ostiolum, which at length disappears, leaving the perithecium rather 
widely perforate. Sometimes the subiculum has a smooth or sub- 
membranous appearance as if collapsed from excessive moisture, and 
then the perithecia are more prominent, but still they retain their 
unpolished tomentose surface. The asci are cylindrical and obtuse 
at the apex. The spores are oblong or oblong-elliptical, uniseriate, 
uniseptate, colored, constricted at the septum, .0009 to .0011 inch 
long, .00035 to .00045 ^^ch broad. In some conditions they appear 
as if involved in a thin colorless mucus.

New Species of Grasses. 
By Geo. Vasey. 
Agropyrum scribnert. — Culms densely tufted, geniculate and 
decuinbent near the base, one to one and a half foot high, rather 
slender. Leaves very short, two or three on each culm, the upper 
sheath twice or thrice as long as the blade, ligule obsolete, blade i- 
1.5 inch long, 1-2 lines wide, rigid, attenuate-pointed. Spike 2-3 
inches long, closely or sometimes 
lax-flowered, but the s^^ikelets al- 
ways longer than the internodes 
of the spike. Spikelets 3-6-flow- 
ered, outer glumes linear-lance- 
olate, 3-5 -nerved, extended above 
into a long point (.5-1 inch), 
smooth except the hispid point. 
Flowering-glumes oblong-lanceol- 
ate, the base 4-5 lines long, 
smooth, about 5-nerved, some- 
times slightly bidentate at the 
apex, the midnerve extended into a strong, spreading or recurved 
hispid awn. Palet equalling the flowering-glume, acute, except on 
the hispid marginal nerves. 
This plant, although in the spike resembHng Ag ropy mm canimm, 
differs notably in its tufted habit, its low size and smooth, rigid, 
sometinies glaucous leaves. It is perhaps the A. caninim, van 
Gmelini, Ld. Mr. Scribner remarks that it is found only high 
up on the mountains near the timber-line, growing in scattered tufts 
in crevices and among the loose rocks, recognized by its low, usually 
prostrate stems, short leaves, with somewhat inflated sheaths, and 
long, divergent, awned spikes. It was collected by Mr. C G. Pringle 
in the Sierras in 1882, altitude 9,500 ft., and distributed as Triticum 
caninum^ L.? It was collected the past season in Montana by Mr- 
F. L. Scribner, to whom I take pleasure in dedicating it, 
/ Sporobolus Buckleyi. — Culms' 2 ft. high, compressed below, as 
are the smooth, striate sheaths; ligule a short, ciliate fringe, also a 
ring of short hairs externally at the top of the sheath. 
Panicle 9-10 inches long, oblong, very open, lax and graceful, 
branches erect, mostly single, occasionally in twos, capillary, the lower
