ROBINSON. — ALSINE.E. 299 



Catskill, and Shawangunk Mts. ; reported from Kittatinny Mts. of N. 

 W. New Jersey (Britton, Bull. Ton-. Club, xi. 128), and recently found 

 in the mountains of Pennsylvania (according to Prof. Porter), of S. 

 Virginia (Small S? Heller), and in N. Carolina (Small), where it had 

 passed as a form of A. glabra, Michx., having been previously collected 

 on Roan Mountain by Gray fy Carey, Smith, aud Scribner* 



A. glabra, Michx. Glabrous, loosely matted, many-stemmed : 

 stems weak, slender, suberect, very leafy, G— 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, lh lines in length, somewhat exceeded by 

 the ovoid capsule. — Fl. 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, Nutt. Glabrous: stems erect, filiform, 2-5 inches 

 high, with spreading branches: leaves linear or lance-linear obtuse, 

 nerveless, 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, 2J— 3^ 

 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, Nuttall ; 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, 

 -t- Seeds much flattened, and margined. 

 A. Douglasii, Torr. & Gray. Thinly glandular-pubescent and 

 somewhat viscid, or nearly glabrous: stems much branched, 2-15 

 inches high: leaves attenuate to filiform points: peduncles filiform: 

 flowers numerous, larger than in the related species, 4-5 lines in 

 diameter : sepals ovate, thin-margined, obscurely or more or less dis- 

 tinctly ribbed : petals obovate, conspicuous • capsule subglobose ; the 

 valves rounded at the apex ; seeds large, smooth, or with fine radiate
