254 PITTONIA. 
barium of my own collecting at Lathrop, 29 April, 1889, and 
from Byron, 10 April, 1892 by Michener and Bioletti. Plants 
collected by myself at Rocklin near Sacramento, 8 March, 1875, 
seem to me to represent this variety in its earliest flowering stage 
in which it would correctly be described as acaulescent, with | 
scapiform peduncles, As for the Chryseis compacta, Lindl., its 
identity, always doubtful to my mind, is now the same; though 
I think it may not improbably be that which in this paper 
I name Z. /acera. 
48. E. tsostiama. Annual, of the size and habit of Æ. 
arvensis, more leafy, more nearly glaucous, apparently somewhat 
succulent: leaves more irregularly dissected, the ultimate 
segments variously unequal and in twos, threes or fives, all 
oblong-linear, obtuse: full grown calyx not seen: corollas, pods 
and seeds as in the last; hyaline inner margin of torus rather 
conspicuous: stigmas 4, all well elongated and almost exactly 
equal, 
Known in but a single specimen, and that in my own herb- 
arium, purporting to have come from among the Montezuma 
Hills, which extend along the northern shore of the Sacramento — 
River in Solano Co., Calif., the collector, W. L. Jepson, 1892. 
However much one might wish to connect this with Æ. arvensis 
as a mere variety, the difference between the two as to the 
stigmas forbids it; and, though hard to define it, there is a 
different aspect to the foliage. 
49. E. OrcuTuaNna. Habit of the foregoing, but not as 
large, stoutish, but foliage small and delicately cut, the petioles 
and rachis slender, all the segments short, narrowly linear, 
acutish : calyx smaller, thin, slenderly almost conical, yet with 
evident and not very short apiculation: corolla 1 inch wide, 
orange-color: torus long and narrow-funnelform, the thin 
herbaceous rim obvious: pods 14 or 1ł inches long. 
Type from Salada, in the Mexican Territory of Lower 
California, C. R. Orcutt, 5 May, 1886, the specimen in Herb.
