ROBINSON. — ALSINEA. 299 
Catskill, and Shawangunk Mts.; reported from Kittatinny Mts. of N. 
W. New Jersey (Britton, Bull. Torr. Club, xi. 128), and recently found 
in the mountains of Pennsylvania (according to Prof. Porter), of S. 
Virginia (Small & Heller), and in N. Carolina (Small), where it had 
passed as a form of A. glubra, Michx., having been previously collected 
on Roan Mountain by Gray & Carey, Smith, and Scribner.* 
A. glabra, Micux. Glabrous, loosely matted, many-stemmed : 
stems weak, slender, suberect, very leafy, 6-12 inches high: leaves 
narrowly linear, spreading, thin, nerveless, equalling or exceeding the 
internodes : peduncles filiform, elongated, spreading, 1-flowered : 
corolla rather broad, considerably exceeding the calyx: sepals ovate- 
oblong, obtuse, nerveless, 1} lines in length, somewhat exceeded by 
the ovoid capsule. — FI. i. 274; Torr. & Gray, Fl. i. 180 in part. 
Alsine glabra, Gray, Man. ed. 2, 58; Chapm. Fl. 49.— On rocks 
in mountains of N. Carolina, Michaux; Table Mountain, Gray ; 
Table Rock, S. Carolina, Vasey; Stone Mt., Ga., Gray; De Kalb 
Co., Ga. Small ; also in the Arroyo of Lamben, near the Mexican 
boundary, Parry. ' 
A. brevifolia, Nurr. Glabrous: stems erect, filiform, 2-5 inches 
high, with spreading branches: leaves linear or lance-linear obtuse, 
herveless, slightly fleshy, 1-4 lines long, commonly much shorter than 
internodes : sepals ovate-oblong, obtuse, only a line in length, with a 
distinct thin white margin: petals rather conspicuous, obovate, 24-34 
lines in length, widely spreading: capsule ovoid, acuminate, a third 
longer than the calyx ; valves ovate, acuminately narrowed almost 
to the tip. — Nutt. in Torr. & Gray, Fl. i. 180. Alsine brevifolia, 
Chapm. Fl. 49. — On rocks, Georgia, Tatnal County, Muttall ; Stone 
Mountain, Canby, Gray, Small; April, May. Apparently the most 
rare and local eastern species. 
* * * Terrestrial annuals of the Pacific Slope: sepals neither indurated nor 
very strongly nerved. 
+ Seeds much flattened, and margined. 
A. Douglasii, Torr. & Gray. Thinly glandular-pubescent and 
Somewhat viscid, or nearly glabrous: stems much branched, 2-16 
inches high: leaves attenuate to filiform points: peduncles filiform : 
owers numerous, larger than in the related species, 4—5 lines in 
diameter : sepals ovate, thin-margined, obscurely or more or less dis- 
tinetly ribbed : petals obovate, conspicuous * capsule subglobose ; the 
valves rounded at the apex ; seeds large, smooth, or with fine radiate
