D. ixmciflorum has a wide range, occurring in middle 

 elevations of the mountains from New Mexico, through Colo- 

 rado, AYyoming and Montana and, according to Hooker, far 

 northward in the British Possessions. Westward it is found 

 in eastern Oregon by Mr. Cusick, who distributes it as " V. 

 Jffrciji, the dwarf form " ; but his specimens have little in 

 common with the plant which Dr. Gray designates as IJ. 

 Jeffrejjh I also refer here Mr. Macoun's plant from " Morley, 

 Juue 12, 18S5," besides two sets of sp3cimens from Vancouver 

 Island by the same botanist, a tall plant from " Cedar Hill, 

 May 26, 1887," and a dwarf state obtained on "Mt. Arrow- 

 smith, July 17, 18S7." The capsule in these far-western 

 plants is less elongated than in the Colorado and Montana 

 type, and the bracts of the involucre as well as the pedicels 

 and calyx are finely i)urple-dotted. 



I may designate as var. monanthum of the present^species, 

 a 1-flowered dwarf of eastern Oregon (Cusick^s Jno. 1528), not 

 more than 2 or 3 inches high, with stamen-tube quite as long 

 as the anthers and like them of a very dark purple, the whole 

 basal part of the corolla-tube of the same color, but separated 

 from the lilac of the segments by a broad pale yellow band : 

 capsules i inch long, splitting readily to the base into 5 valves. 

 This may easily prove distinct ; but one wishes to know more 

 of its habits, special location, etc. 



DoDECATHEON CusicKii. Like the type of the preceding in 

 subterranean characteristics; the whole herbage more or Ices 

 viscid with a close glandular pubescence: leaves from 

 coarsely dentate to entire : coloring of flowers as m the 

 l*ist, but stamen-tube shorter: pedicels numerous, turbi- 

 nately accrescent and 10-striate under the mature capsules , 

 ftese oval, acute, scarcely surpassing the calyx, completeJy 



S-valved from the apex. , 



Tbe type of this is Mr. Cusick's 1527, said to grow on dr> 

 i^ouutain ridges of eastern Oregon, at an altitude of 4UUU
