326. Geo. Vasey (402) beschreibt die folgenden neuen Species: Stipa Seribneri 
„Culms 2—3 ft. high, stout, erect; lower leaves half as long as the culm, smooth, flat 
below, becoming involute at the long acuminate point; upper sheath enclosing the base of 
the panicle, which is narrow, erect, and 6—8 inches long, the branches in twos or threes 
‚ and appressed; outer glumes unequal, lower one 6-8 lines, upper about 5 lines long, both 
3-nerved, acuminate; flowering-glume 3—5 lines long, hairy, hairs longer above, and at 
the apex forming a white crown a line or more long; awn rather siender, 8—9 lines long, 
not hairy; stipe short, very acute, pubescent; palet less than a line long, obtuse and 
adherent to the grain“. — Festuca confinis, „Culms about 3 ft. high, rather rigid, smooth, 
radical leaves half as long as the culms, those of the culm 2 or 3, the sheath loose and 
shorter than the internodes, blade flat, 6 inches long, striet; branches in twos or threes, 
unequal, erect, the longest twice as long as the internodes, subdivided below the middle, 
rhachis and branches nearly smooth; spikelet oblong, 3- to 5-flowered, the outer glumes 
ovate-lanceolate, theis, smooth, l1-nerved, the upper one about 3 lines long, the lawer a 
little sharter; flowering-glumes about 3 lines long, prominently S-nerved, scabrous, rather 
rigid, rocended on the back, acutish to very acute, but not awned; palet about equaling 
its glume, scabrous-ciliate on the keels, adherent, to the grain“. — Elymus Saundersüi. 
„Culms tufted, 2-3 ft. high, slender but firm, smooth, radical leaves involute-setaceous, 
about half as long as the culm, culm-leaves about 3, the sheaths smooth, the upper one 
long, the blade rigid, 5-6 inches long, finely scabious, becoming involute, ligule obsolete; 
panicle 5—7 inches long, rather cylindrical and flexible, rhachis with 20 or more joints, 
which are 3 to 4 lines apart; spikelets 2- to 4-flowered, generally in pairs, at least below, 
frequently singly above and sometimes through out; upper glumes linear-lanceolate, 3- to 
- 5-nerved below, with 2 short teeth at the apex, scabrous on the mid, nerve and running: 
into a slender scabrous awn an inch or more in length; flowering-glumes lanceolate, 5-nerved, 
finely scabrous, 2-toothed at apex, 5 lines long to the aron, which is steuder and 1 to 1.5 
inch long; palet wide and flat, nearly a long as its glume, bifid, scabrous on the 2 sharply 
flexed keels. The coole spike generally of a purple color.“ 
327. Geo. Vasey (403) bildet ab Cathestechum erectum Vasey and Hackel und 
beschreibt dasselbe wie folgt: Culms tufted, erect, 6 to 9 inches high, throwing out from 
the base long arched runners, of 2 or 3 joints, the joints villous and bearing a tuft of 
shart leaves. The leaves are mostly at the base 2 to 3 inches long, narrow, plane or 
becoming somewhat at involute, sparsely hairy ou the margins, striate. Culm-leaves 2 or 
3, distant, 1 to 2 niches long; ligule a ciliate ring. 
Some of the culms are simple, and others develop at the upper sheath 2 to 4 lateral 
peduncles, each 2 to 4 inches long, forming a kind of cymose cluster. Each of these pe- 
duncles, as well as the main stem or rhachis, bear a raceme, about one inch long, of from 
5 to 9 approximate, sessile fascicles of flowers. Each fascicle consist of three (rarely 4) 
spikelets. The lateral spikelets of each fasciele are 2-flowered, the middle spikelet usually 
3-flowered, frequently with a fourth imperfect flower. Sometimes also the lateral spikelets 
have a sterile pedical or an imperfect flower. The outer glumes are colored and very 
unequal; the lower one is minute (one-half line long), broodly cuneate, truncate or somewhat 
toothed at the apex; the upper om is lanceolate, compressed, somewhat keeled, l1-nerved 
acute, or in the central spikelet 2-toothed and mucronate, 1 to 1.5 line long, villous externally. 
The flowering-glumes are oblong, about 1.5 line long, 4-lobed, with the nerves extended into 
awns between the lobes, the awns as long as, or in the central spikelet considerably longer
