258 PITTONIA, 
green showing in strong contrast the whitish strie, only 
sparingly leafy, the secondary branches few, ending in very 
long naked peduncles; scarcely more than glaucescent, usually 
glabrous, only the basal parts now and then scabrous ; leaves 
not small, but their segments few, the main divisions cuneiform, 
parted into long and narrow moderately divergent ultimates all 
acutish : calyx very thin and translucent, ł inch long including 
the elliptic-ovoid body and slenderly tapering long point; 
corolla small for the plant, light-yellow: pods slender, very 
long, 24 to 34 inches; torus very small, with rim greatly re- 
duced, hardly more obvious than the inner margin. 
At several stations among the foothills of the San Bernardino 
Mountains, southern California, at an altitude of about 1500 
feet, S. B. Parish, who distributed it from Waterman’s Cañon, 
1 May, 1888, as Æ. Mexicana, Greene, doubtless on my authority ; 
for it is somewhat related to that species, though a much larger 
plant, and not subacaulescent ; but in Herb. Calif. Acad. as well 
as in my own, certain older and fruiting specimens on the same 
sheets and under the same label, specially gathered by Mr. 
Parish doubtless for the purpose of exhibiting fruit and seeds, 
are Æ. vernalis, as may be seen by their different habit, broad 
short leaf-segments and short pods, these invariably of no more 
than half the average length of those of Æ. straminea, which I 
thus name not so much in allusion to the pale color of the corol- 
las as to the thin and somewhat straw-like hollowness of the 
striated stems, 
55. E. VERNALIS. Æ. peninsularis, Greene, partly, of Bull. 
Cal. Acad. i. 183. Annual, 6 to 12 inches high, with a tuft of 
upright basal leaves and 5 to 10 or more rigid and not slender 
ascending rather sparsely leafy and few-flowered branches, & 
single central earliest peduncle scapiform and half as high as 
the proper branches; herbage glabrous, glaucous: small leaves 
rather compact, their ultimate segment obovate-oblong or ob- 
lanceolate, acutish, moderately divergent: calyx thin, oblong- 
conical, little more than 4 inch long, slenderly and not very 
shortly apiculate: corolla golden-yellow, about 14 inches broad,
