216 PITTONIA. 
inch long; keel faleate, densely ciliate in the middle: ovary 
very villous. 
Crooked Creek, in the southeastern part of Oregon, July, 
1886, Mrs. R. M. Austin. Species near L. rivularis, but dis- 
tinguishable at a glance by the stout hollow stems, and 
especially by the remarkably conspicuous liguliform stipules, 
of which the lowest are an inch and a half long; all very 
hairy. The color of the flowers, which are faded in the 
specimens, is probably blue. 
LUPINUS varticoLor, Steudel, Nom. (1841) = L. versicolor, 
Lindl. Bot. Reg. xxiii. t. 1979 (1837) — L. Franciscanus, 
Pittonia, i. 64 (1887).—And so this beautiful and quite local 
Californian lupine was known to Lindley, whose figure from 
a specimen cultivated in England I had quite overlooked. 
East American authors are more or less excusable for losing 
sight of any number of our species; not so we who live in 
the field. The present plant may not have been known to ' 
Steudel except through Lindley's work; but he discovered 
that the Lindleyan name was precluded by an earlier and 
Mexican L. versicolor of Sweet. 
PTELEA CRENULATA. Ten to twenty-five feet high, strongly 
aromatie when fresh, but with an agreeable spiey odor when 
dry, glabrous except the tomentulose flowers and a faint 
pubescence on the lower face of the leaves : mature leaves of 
a bright yellowish green beneath, darker above; leaflets 
obovate with abruptly cuneate base, obtuse or acute, 1 to 2 
inches long, erenulate, or crenate-serrate and the serratures 
crenulate : filaments villous near the base: samara, including 
the broad wing, ł inch long and of somewhat greater breadth, 
in maturity truncate or emarginate at both ends, frequently 
triquetrous and 3-seeded.—P. angustifolia, Brew. & Wats. 
Bot. Cal. i. 97, not of Benth. 
I am too familiar with the Mexican P. angustifolia to con- 
found our Californian species with it. The present shrub 
has more nearly the foliage and aspect of the East American
