95. E. RosTELLATA. Habit of the last, or perhaps more widely 
branched and diffuse, far more slender, glaucescent, lower petioles 
and parts of stems more or less definitely scaberulous; leaves 
and flowers very much smaller, the former cleft into not many 
nor widely divergent-long and very narrow linear segments: 
calyx about 4 lines long, including the slender and not short 
taper point, the body ovate-elliptic: corollas many, little more 
than 3 inch wide, nearly rotate, orange-color: stamens 12 to 16, 
filaments long and filiform, anthers much longer, narrowly 
linear: stigmas 2, with 2 short rudiments: pods 2 inches long, 
extremely slender, vacant for 4 inch at summit, this part form-

ovoid, with a long apiculation at one end, the surface lightly 
reticulate. 
Known only in a single sheet of two fine, even perfect speci- 
mens in Herb. Calif. Acad., from Coloma, El Dorado Co., Calif., 
30 May, 1901, by G. P. Rixford. Very distinct from all other 
species, even from Æ. caruifolia, to which it is nearly akin. 
96. E. vaccarum. Size of the last, equally glabrous and 
glaucous, more upright, much more sparingly branching, all the 
stems, branches and even peduncles stouter and evenly striate, 
not angular: segmentation of leaves much narrower and finer : 
calyx ovoid with abrupt and prominent apiculation: corolla 
larger; pods slender, straight, 24 inches long; seeds not seen.

97. E. OREGANA. Annual a foot high, freely and somewhat 
decumbently branched from the base, the branches subdivided, 
leafy and floriferous throughout, with no pronounced tuft o 
basal leaves even at first, all the stems and branches, about 
5-angled and not striate ; herbage glabrous, glaucous; leaves 4 
smallish, the segmentation narrowly linear, acute, moderately 
divergent, the ultimate segments of the very earliest leaves a
