1. CLARKIA PULCHELLA Pursh, FI. 1:260. 1814.—It is not 
necessary to cite specimens of this beautiful and distinctive species. 
Its range is greater, however, than generally indicated in the books. 
Although most frequent from British Columbia to western Idaho 
and California, it crosses Montana and has been secured in the 
Black Hills of South Dakota. Often cultivated in the eastern 
states, it is of spasmodic occurrence there as a weed in newly seeded 
grounds, etc. 
2. Clarkia amoena (Lehm.), n. comb.—Oenothera amoena Lehm. 
Ind. Sem. Hort. Hamb. 8. 1821.—This species and the next one are 
well marked by the character of the anthers curving after dehis- 
cence. There is some variation in this, however, the cells some- 
times being fertile to the tip and then tardily recoiling. Two 
noteworthy, but in themselves variable, color forms occur. These 
may be known as forma concolor (Jeps.), n. comb.—Godetia amoena, 
var. concolor Jeps. Fl. Mid. 334. 1901; and forma Lindleyi (Dougl.), 
n. comb.—O. Lindleyi Dougl. Hook. Bot. Mag. pl. 2832. 1828; 
G. amoena, var. Lindleyi Jeps. Univ. Cal. Publ. Bot. 2:329. 1907. 
The latter is distinguished by the presence of a dark central blotch 
in the petals.

3. Clarkia arcuata (Kell.), n. comb.—Oenothera arcuata Kell.

Acad. 8:599. 1873; G. arcuata (Kell.) Jeps. Univ. Cal. Publ. Bot. 
23335. 1907.—HoweE Lt, Fl. N. W. Am. 235. 1900, credits this 
species to the Northwest, and he is followed by FryE and RI1cG, 
Elem. Fl. N. W. 159. 1914. JEPSON (loc. cit. 335 and 322), how- 
ever, restricts its range to central California, and we have seen no 
specimens from Oregon.
