P. borealis, Drsr, p. 58. Strike out the closing sentence in parentheses, and add the 

 following species: 



P. Egaliksensis, HORXEM. Slender, not at all mealy : leaves oval or lanceolate-ovate, 

 entire or margins merely undulate, mostly slender-petiolcd : umbel 3-6-flowered : pedicels in 

 fruit elongated and strict : calyx narrow, in fruit oblong-cyliudraceous, with short teeth : 

 limb of the corolla very small ; the lobes only a line or two long, much shorter than the tube, 

 cleft nearly to the middle into oblong-linear segments. Fl. Dan. t. 1511; Lehm. Prim. 

 63, t. 7; Lange, Medd. Grcenl. 71. Northern Labrador, Lieut. Turner. (Greenland.) 



P. angustifolia, TORR., p. 58. Strictly 1-flowered, or very rarely 2-flowered in largest 

 plants : involucre a single minute or small bract, sometimes the rudiment of a second bract : 

 calyx green. Add the following nearly related species : 



P. Cusickiana. Larger : leaves oblong-spatulate or narrower, 2 inches long, entire, or 

 rarely a deuticulatiou : scapes 3 to 6 inches high, 2-4-flowered : involucre of 2 or 3 conspicu- 

 ous unequal bracts : calyx green and with a whitish line down from the sinuses of the cam- 

 panulate tube ; its lobes from lanceolate to subulate, about the length of the tube and nearly 

 equalling the tube of the violet (rarely white) corolla; lobes of the latter retuse. P. angus- 

 tifolia, var. Cusickiana, ed. 1, 393. Rocky hills, Union Co., E. Oregon, flowering in earliest 

 spring, Cusick. 



P. Rusbyi, GREENE. Still larger : leaves 2 to 5 inches long (including the margined 

 petiole), thinner, oblong-spatulate, mostly callous-denticulate : scapes 5 to 10 inches high, 

 6-10-flowered : involucre of 3 or more small subulate or ovate bracts: calyx-tube white and 

 as if farinose at base, campanulate, longer than the ovate-triangular lobes: corolla "deep 

 purple, with yellow eye"; its tube longer than the calyx; lobes obcordate. Bull. Torr.

 son, Santa Rita Mountains, Arizona, Pringle. 



4. DOUG-IjASIA, Lindl., p. 59. Species re-characterized and augmented. 

 Pubescence (when there is any) of the pedicels and stems of 3-4-forked or stel- 

 late short hairs. Flowers in most species occasionally unibracteolate under the 

 calyx. 



D. nivalis, LINDL. Leaves, c. canescent with minute and dense 2-3-forked pubescence, 

 not ciliate, linear, mostly quite entire, mainly in rosulate clusters, from which the stems are 

 repeatedly and commonly umhellately proliferous : flowers in 3-7-rayed umbels, with 

 involucre resembling a leaf-cluster or reduced to ovate or subulate bracts : corolla-tube 

 hardly exceeding the calyx. To references add: Hook. Ic. PI. ii. 130. Montana, 

 Brandegee, &c. 



Var. dentata. A coarser form, with larger (4 to 6 lines long) and broader leaves 

 often spatulate, either entire, or with a few denticulations or coarse teeth. D. dentata,
