250 PITTONIA. 
slender horns: torus small, turbinate, with reduced but visible 
cartilaginous ring in place of rim: seeds spherical, reticulate. 
Very singular species, from San Sebastian, Mexican province 
of Lower California, collected by Mr. Brandegee, 28 April, 1889, 
the type in Herb. Calif. Acad. The specimen is very mature, 
only two buds and three corollas remaining, but with many 
growing ovaries, all showing the singularly accrescent and per- 
sistent bases of two of the stigmas. The plant is doubtless 
not maritime, but an inland or at least upland species. 
42. E. microtopa. Annual, branched from the base and 
strongly decumbent if not more depressed, the branches a foot 
long or more, remarkably stout but somewhat fistulous, finely 
striate, sparsely leafy with small foliage and notably false-dicho- 
tomous; herbage glabrous, glaucous; leaves of the branches 
scattered and much reduced, the basal known only by the long 
and uncommonly slender petioles; segments of the rameal short, 
linear, moderately divergent : calyx } inch long, firm, ovoid, with 
very short blunt point: corolla orange, about 1 inch broad: 
pods very small forthe plant, 1 inch long or little more: torus 
turbinate, with thin deflexed rim and hyaline inner margin of 
about equal width: seeds short-ovoid, transversely sinuate- 
rugose rather than reticulate. 
Carrizo Plains, interior of Southern California, 12 June, 1902, 
Alice Eastwood. A strongly marked species, of which the early 
stages of development are, of course, unknown. The locality 18 
a peculiar one. 
43. E. LACERA. Annual, branched from the base and the 
numerous branches ascending, or almost prostrate, a foot long 
or more, freely and as if dichotomously branched ; leafy and 
floriferous throughout, glabrous, glaucous: leaves of very open 
dissection, sharply cut into narrow-linear nearly divaricate pri- 
mary segments, the ultimate 3 merely divergent, all acute : pe 
duncles short, slender: calyx thin, + inch long, subconic-oblong, 
with abrupt short and minnte apiculation: corolla golden-yel-
