* * Flowers solitary terminating the leafy shoots : tube of the corolla barely equalling the calyx : 

 leaves more or less imbricated in the manner of D. Vitaliana. 



D. montana, Gray. Pulvinate-cespitose, an inch or two high, nearly glabrous : leaves 

 subulate, minutely somewhat ciliate, 2 lines long, somewhat interruptedly imbricate-clus-

5. ANDROSACE, Tourn. (Ancient Greek name of some sea-plant or 

 zoophyte, curiously transferred to these little plants of the mountains.) Small 

 annuals or perennials, of various habit, numerous in species in the Old World, 

 few in the colder regions of the New : fl. summer. 



* Perennials, prolifcrously branched at base and cespitose : leaves rosulate-imbricated at the base 

 of the many-flowered scapes : capsule usually few-seeded : umbel several-flowered. 



A. Chamsejasme, Host. Leaves in more or less open rosulatc tufts, from lanceolate 

 to oblong-spatulate or ovate, carinate-1-nerved (3 to 6 lines long), at least their margins 

 with the scape (1 to 3 inches high) and somewhat capitate umbel villous with many-jointed 

 hairs: corolla white with yellowish eye (3 or 4 lines in diameter). Koch, Syn. ed. 2,071 ;

* * Annuals, acaulescent, with slender root, an open rosulate circle of leave*, and naked scapes, 

 bearing an invohicrate few-many-flowered umbel: capsule many-seeded: corolla white, small. 



-K- Calyx-tube obpyramidal in fruit, whitish with conspicuous green teeth, which mo>tly surpass 

 the capsule. 



A. OCCidentalis, Pursh. Minutely pubescent, not over 3 inches high : radical leaves 

 and those of the conspicuous involucre oblong-ovate or spatulate, entire, sessile : scapes 

 diffuse : bracts of the involucre ovate or oblong : lobes of the calyx triangular-lanceolate : 

 oblong or deltoid, as long as the tube, still longer in fruit, foliaceous : lobes of the corolla 

 oblong, shorter than the calyx. Fl. i. 137; Nutt. Gen. i. 118. Banks of the Missouri

A. septentrionalis, L. Almost glabrous : leaves lanceolate or oblong-lanceolate, nar- 

 rowed at base (often into a sort of winged petiole), from irregularly denticulate to laciniate- 

 toothed: scapes erect, usually numerous, 2 to 10 inches high: bracts of the small involucre 

 subulate : umbel several-many-flowered : pedicels filiform, mostly long : lobes of the calyx 

 mostly shorter than the tube, rather shorter than the obovate lobes of the corolla, from 

 triangular to subulate-lanceolate, acute. Lam. 111. t. 98, f. 2; Fl. Dan. t. 7; Bot. Mag.

t -I Calyx-tube hemispherical in fruit ; the short teeth barely greenish and rather shorter than

A. flliformis, Retz. Glabrous: leaves, scapes (1 to 4 inches high), and pedicels nearly 

 as in the preceding or more capillary : flowers less than a line and globose capsule only a 

 line long: calyx-teeth broadly triangular, shorter than the very small corolla. Obs. ii.
