P. nivalis, Pall. Resembles the preceding, but runs into much smaller forms : leaves 

 from one to inches long, thickish, either entire or closely denticulate: umbel 2-10- 

 flowered : bracts of the involucre ovate-subulate : pedicels usually short : calyx-lobes 

 oblong or broadly lanceolate, shorter than the oblong capsule : corolla lilac-purple ; the

 glandular. 



P. cuneifolia, Ledeb. Leaves all rosulate-clustered on the thick short crown, obovatc- 

 cuneate, coarsely laciniate-toothed (3 to 12 lines long), mostly narrowed at base into a long 

 and slender petiole : scape 2 to 4 inches high, 1-several-flowered : corolla purple ; the lobes 

 deeply 2-cleft (3 to 5 or even lines long), as long as the funnelform tube. Mem. Acad.

4. DOUG-L ASI A, Lindl. (Named for David Douglas, of Scotland, an inde- 

 fatigable explorer of N. W. Ainer. Botany.) --Depressed and tufted little herbs ; 

 the stems branching or proliferous, suffrutescent, or at least persistent ; the leaves 

 small, linear, imbricated or rosulate on the branches, or some of them scattered 

 and alternate. Flowers solitary or somewhat umbellate, small. -- Lindl. in

* Flowers umbellate-clustered from the uppermost rosulate tuft of leaves: tube of the corolla 

 longer than the calyx. 



D. nivalis, Lindl. Canescent with fine close pubescence, 3 or 4 inches high, repeatedly
