ESCHSCHOLTZIA. 271 
dentate segments: peduncles filiform, terete, tortuous in flower: 
calyx very thin, ovoid or obovoid, scarcely apiculate, hardly 2 
lines long : torus a short cup, thinnish below the margin, cor- 
olla 4 inch broad or less: stamens few and definite: pods 
slender, 14 inches long, immature, torulose. 
Most peculiar species, known by two sheets in U. S. Herb., 
one by M. E. Jones from Hawthorn, Nevada, near the Califor- 
nian boundary, the other by C. A. Purpus from “ Erskine Creek, 
southeastern California,” but Mr. Purpus’ specimens are mixed 
with one of perhaps Æ. glypfosperma, and perhaps others of true 
E. minutiflora. 
79. E. RUTÆFOLIA. Small annual, branched, from the base, 
leafy throughout, 3 to 6 inches high, glabrous, very glaucous : 
basal leaves not densely tufted, all on petioles, much longer 
than the small blades, these almost simply ternate, some of the 
largest imperfectly biternate, the divisions merely lobed, the 
lobes broadly cuneiform and 2 or 3-toothed at the obtuse sum- 
mit, those of the upper part of the branches flabilliform, cut 
into 3 approximated segments each cuneate and, at the broad 
truncate summit lightly 3-toothed: flowers small, short-pedun- 
cled in the axils of the long-petioled stem-leaves which greatly 
surpass them ; buds scarcely ? inch Jong including the com- 
paratively large broad-obconic torus, obovate-oblong, merely 
acute, the calyx very thin and translucent; petals light-yellow, 
only + inch long, apparently fugacions: pod and seeds not 
seen. ; 
= A single sheet of specimens in Herb. Calif. Acad., collected 
at Havilah, Kern Co., Calif., 15 April, 1891, by Brandegee. The 
cut of the leaves is peculiar, and not so much that of rue, as of 
the little fern called Ruta muraria. 
80. E. BITERNATA. Very slender annual, with few and erect 
sparsely leafy branches from the base, glabrous, glaucous: 
basal leaves small on short and slender petioles, these quinately 
ternate, the lobes rather short, all the others merely biternate,
