224. Corydalis Caseana Gray.
Syn. Corydalis Bidwelliae Wats.
Butte Creek, northern Butte County, in the Transition Zone of
the Sierra Nevada at 1500 m. altitude.
Growing with roots in water along the margin of Butte Creek
where shaded by Alnus tenuifolia, Comus pubescens, and Populus
trichocarpa, associated with Senecio triangularis and Lilium parvum.
Petals white, suffused with wine-red, the inner petals tipped
with wine-red; spur either straight or slightly curved. C. Bid-
welliae was probably based on a less hydrophytic form, since at
least in some cases (H.M.H. 9308) it grows in soil that is only
moist. Its type locality is given as “above Chico,” which would
locate it not far from the station where this set (no. 9796) was
gathered. The plants with narrow leaf-segments and whieh might
therefore be taken for C. Bidwelliae, grew where exposed to the
sunlight, while those with broader segments grew where shaded
by shrubs.
Collected by H. M. Hall (no. 9796), July 28, 1914.
