Smelowskia^ calycina, Mey. (Hutchinsia, Desv.) Leaves mostly radi- 

 cal; flowers white, in dense corymbs, the limb of the petal roundish; stem 

 (6' high) elongating in fruit.— Rocky Mountains, from Colorado to lat. 57°, and 

 Behring Strait. East Humboldt Mountains, Nevada, and in the Uintas; 

 10-11,000 feet altitude; August, September. (100.) 



Erysimum cheieanthoides, L. From Pennsylvania to Colorado, the 

 Arctic Circle and Washington Territory. Reese Valley, Nevada, and in the 

 Wahsatch and Uinta Mountains ; 5-6,500 feet altitude ; June, July. (101.) 



Erysimum asperum, DC. From Missouri to Western Texas and 

 Southern California, and northward to lat. 57°. Frequent in the mountains 

 of Nevada and Utah ; the stem simple and leaves nearly entire ; 5-12,500 

 feet altitude ; May-August. (102.) 



Var, PUMiLUM. An early spring form from the foothills near Carson 

 City, Nevada ; branching from the base and leaves more dentate. It does not 

 appear to differ from E. pumilum, Nutt., and may be distinct. April. (^103.) 



Var. iNCONSPicuuM. With small flowers, the petals but half longer than 

 the (3-4" long) sepals. Collected also by Bourgeau. Diamond- Valley, 

 Nevada. (104.) 



Stanleya^ pinnatifida, Nutt. Stems 2-3° high, decumbent at base, 

 several from the same rootstock ; lower leaves lyrate-pinnatifid, lobes some- 

 what lanceolate ; upper leaves entire, lanceolate, narrowed at base to a slen- 

 der petiole; filaments much elongated; siliques 2' long, somewhat torulose, 

 twice longer than the stipe. — The leaves are often nearly all entire, forming 

 in the absence of the lower ones the 8. integrifolia, James, which cannot 

 rank even as a variety. S.fruticosa and heterophylla, Nutt.^ are probably also 

 include,d. The woody base is sometimes an inch or more in diameter, show- 

 ing 10-12 annual rings. From Western Iowa to the headwaters of the Platte 

 and Snake Rivers, southward to Northern Arizona and New Mexico. Valleys 

 of Nevada and foothills of the Wahsatch ; 4,500-5,000 feet altitude ; June, 

 July. (105.) 



1 SMELOWSKIA, C. A. Meyer. Sepals short, equal. Siliole rather short, narrowed at each end, 

 somewhat tetragonal or laterally compressed ; valves concave, submemhranous, with Included filiform 

 repliun and memhranous septum ; style short and stigma simple. Seeds few, in one row, immarginate ; 

 funiculus setaceous, free ; cotyledons incumbent. — Perennial hoary-tomentose suhciBspitose herbs, with 

 1-2-pinnatifid leaves and bractleas flowers. Benth. & Hook. 



^ STANXiEYA, Nutt. Sepals long, spreading. Petals narrow, elongated, with long claws. Anthers 

 twisted. Siliques long-stipitate, slender, nearly terete, subcompressed ; valves 1-nerved ; style short or 

 none ; stigma simple. Seeds in one row, oblong, pendulous ; cotyledons incumbent.— Perennial, glabrous, 

 glaucous ; flowers yellow, in long, strict, many-flowered, bractloss racemes. Bentii. & Hook.
