1915) "Torrey,— The Varieties of Cardamine oligosperma — 157 
the leaves of which have only 3 leaflets,— doubtless merely a leaf 
variant. 
Turning to O. E. Schulz’s recent Monographie der Gattung Carda- 
mine, we find that all these forms have been recognized; but unfor- 
tunately the fact that Schulz was unfamiliar with the type of 
Nuttall's Cardamine oligosperma, and that his conception of the rela- 
tions of the various subspecific categories was not altogether in accord 
with those sinee set forth in the International Rules, necessitate 
the following changes. 
CARDAMINE OLIGOSPERMA Nutt. in T. & G. Fl. N. Am. i. 85 (1838- 
40). C. hirsuta, subsp. oligocarpa, proles lasiocarpa O. E. Schulz. 
Engl. Bot. Jahrb. xxxii. 470 (1903). Nuttall’s type, from “Oregon 
woods," preserved in the Gray Herbarium, bears immature fruit, 
and has the stems, petioles, leaflets, and pods beset with short stoutish 
spreading hairs; and the inflorescence bractless. "This, the typical 
form of the species, is confined to Washington and Oregon.— WASHING- 
TON: wild in garden, Bingen, Klickitat Co., Suksdorf, no. 7453; wet 
places in forest at Prindle, Skaminia Co., Suksdorf, no. 7487; bottom 
lands near mouth of Lake River, Clarke Co., Suksdorf, no. 2301. 
OnEGON: Oregon woods, Nuttall; wet places in dense forest at Linnton 
near Portland, Suksdorf, no. 1816; Sauvie's Island, 1882, Howell. 
var. lucens, var. nov., siliculis glabris, pilis caulis saltem super 
foliis carentibus. Pods glabrous, hairs of the stem absent, at least 
above the leaves.— C. oligosperma Am. auth. in part. C. hirsuta 
subsp. oligosperma O. E. Schulz, l. c., 468.— 'This smooth variety is 
much more abundant than the species, extending south to California. 
The following representative specimens may be cited.— WASHINGTON: 
damp places, common at Bingen, Klickitat Co., Suksdorf, no. 7452 
(Type in Hb. Gray.); shady rocky stream-banks, Waitsburg, Horner, 
no. R79B64. Oregon: Chenowith Creek, Wasco Co., Oregon, 
Sheldon, no. 10,200; bogs near Portland, 1884, L. F. Henderson. 
CALIFORNIA: Mt. Diablo, 1878, Lemmon; foothills near Stanford 
University, Santa Clara Co., Baker, no. 517; back of Alum Rock Park, 
Santa Clara Co., Heller, no. 8484; common in moist shady ground, 
vicinity of Eureka, Humboldt Co., Tracy, no. 1009. 
var. bracteata (O. E. Schulz), n. comb. C. hirsuta, subsp. oligo- 
sperma, var. bracteata O. E. Schulz, |. c., p. 470. This plant, which re- 
sembles var. lucens in its lack of pubescence, but differs from that and 
from the species in having narrow simple or trifid bracts at the base 
of the inflorescence or throughout, is known only from two collections 
of Mr. Suksdorf in Klickitat Co., Washington; viz., low wet places,
