P. borealis, Dhbt, 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-petioled : umbel 3-6-tlowered : pedicels in 

 fruit elongated and strict : calyx narrow, in fruit oblong-cylindraceous, with short teetli : 

 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. Groenl. 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 deuticulation : 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, al)out the length of the tube and nearly 

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

 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 liigh, 

 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.

4. DOUGLiASIA, 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 umbellately proliferous : flowers in 3-7-rayed umbels, with 

 involucre resembling a leaf-cluster or reduced to ovate or sui)ulate bracts : corolla-tube 

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

 Branderjee, &c. 



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

 often spatulatc, either entire, or with a few dcnticulations or coarse teeth. — D. dentata,
