ESCHSCHOLTZIA. 253 
less; torus under them with distinct coriaceous but not wide 
rim: seeds slightly elongated, favose-reticulate. 
Known only from some unmentioned station in Colusa Co., 
where it was collected by Mr. Brandegee, Apr., 1889. One speci- 
men in Herb. Calif. Acad., another in Herb. Parish. The 
habitat, though not so very far removed from that of E. tenui- 
secta is on the opposite side of the interior valley of California 
and therefore in another climatic region. The species is most un- 
like Æ, senuisecta in habit, and has different stigmas and seeds 
47. E. arvensis. Æ. compacta, Greene, Fl. Fr. 285, in part 
and excl. syn. Æ. tenuisecta, probably not Æ. compacta, Walp. 
Rather stoutish annual 8 to 16 inches high, branched from the 
base, ascending or decumbent, moderately leafy, glabrous, glau- 
cescent; leaves cut into narrowly linear or linear-cuneiform 
acute segments, the ultimate ones deeply and subequally 3- 
cleft: peduncles stout, several of the earlier scapiform and sur- 
passing the copious foliage; calyx large, oblong-conical, dia- 
phanous, shortly and slenderly apiculate : corolla open campanu- 
late, the earlier ones more than 2 inches broad, deep golden- 
yellow : filaments many, the outer short and subulate, the inner 
linear and longer, all dark-purple under the anthers ; stigmas very 
slender and unequal: turbinate torus with rather broad red- 
purple rim; pods 2 inches long or more: seeds small, short- 
ovoid, acutish at one end, strongly reticulate. 
Var. pILATATA. More upright, even rather strict; ultimate 
segments of leaves dilated upwards and obtuse, usually mucronu- 
ate. 
Large and fine annual species, inhabiting the middle sections 
of the interior valley of California, common along the lower 
San Joaquin, often abounding in grain fields about Lathrop, 
Tracy, Byron and apparently in similar situations of the lower 
Sacramento. Typical Æ. arvensis was distributed by Mr. O. F. 
Baker, under n. 2778, from Tracy, in 1903. What I have placed 
as var. di/ata/a seems the more common form, and is in my her-
