365. Corydalis caseana Gray, Proe. Am. Acad. 10 (1874) 69.
Jonesville, Butte County, alt. 1500 m.
In and beside eold running water, always in stony or gravelly
soil. This is identical with no. 224 of these exsiecata, and is
reissued to show the plant’s place in the local flora. It almost
always occupies the larger gravelly springs and permanent gravel
bars. The root system is very ample and stout. Flowering lasts
through the summer. The color is variable in the amount of pink
or red present with the white, but there is no real blue (cf. apice
caerulescente of the diagnosis). The discharge of seed when the
plants are disturbed is more than audible. The type locality, Big
Spring, in Big Meadows, is submerged in the artificial Lake
Almanor. Jonesville is positively, as suggested on the label of
no. 224, the type locality of C. Bidwelliae. This broader form is
produced by humus in the soil as well as by shade.
Collected by E. B. Copeland, July 3, 1929.
