 inches liigh : k'uvea pelioled, luucli cu)\vile(l on the short sterile shoots, scattered on 

 the erect llowering stem, thickish, mostly pinnately parted into 3 to 7 shortdincar

 E. L. Greene), and on tlie noitlicrn border of the State (Kcwbemj) : thence to Oregon and tlie 

 Rocky Mountains. The var. crclvifolia. Gray {O. crcbrifulia, Nutt. ), with entire and more 

 glabrous leaves, occurs in the northeastern part of Nevada. 



» * Annual, low and s^ircadiny, looseli/ branched: Jlowers fewer, more leafy-hracted, 

 in less dense clusters : lobes of the ccdyx and leaves conspicuously cuspidate-tipped. 



33. Gr. pumila, Nutt. Slightly woolly-pubescent : leaves narrowly linear, en- 

 tire or witii 2 to -1 narrow lobes : tube of the corolla (3 or 4 lines long) about twice 

 the length of its lobes ami of the calyx-lobes : lilaments shorter than the lubes of

 natifid into several small and irregular lobes; those of the branches mainly clustered 

 around the flowers (half an inch long) : corolla barely 2 lines long, its tube hardly 

 exceeding the calyx-lobes : anthers almost sessile in the throat : ovules only a pair 

 in each cell. — Bot. Mex. Bound. 147; Watson, Bot. King Exp. 268. 



Mountains on the western borders of Nevada, JFatson. Thence east to Utah and the borders 

 of Texas. This and tlie ])receding will doubtless be detected within the State. 



§ 9. Flowers thyrsoid-panicled, hardly bracteate: corolla (red) salverform with a lomj 

 and sliijhtiy funnel/or m tube, very much suipassiny the calyx: stamens inserted 

 in or below the throat of the corolla, not longer than its lobes : anthers sIlotI : 

 ovules numerous in each cell: biennials, merely pubescent, with simple virgate 

 stem and lan/c showy blossoms. — ll'OMOl'ai«, Bonth.

 l»arted into 7 to 13 lin(^ar mucronulato divisions, or in tho upper leaves fewer: 

 llowers in small clusters, disi)osed in a simple or sometimes branching virgate naked 

 panicle: calyx commonly glandular ; its lobes subulate: corolla scarlet (varying to 

 pink or rarely white) ; its tube an inch long, 2 to 4 times tho length of the ovate-

Var. Bridgesii, Gray, 1. c. : a rather low form, loosely somewhat few-flowered: 

 corolla said to be j)urple: calyxdobes short and broadly triangular-subulate or ovate-

Rocky ravines, kc. Sierra Nevada, tliroughout its length, to Oregon and Idaho, and east to the 

 Rocky Mountains. The variety collc<.ted only liy Jirid(iis, — station in California unknown, — but 

 various specimens of the Sierra Nevada apinoach it. Flowers "very fragrant," even more showy 

 than those of the related O. ctironopifulvi of the Southern Atlantic States. Stamens in some in- 

 dividuals included, in others consj)icuously exserted ; these with style ecjually or even more
