262 PITTONIA. 
61. E. PAUPERCULA. Low annual, slender, sparingly branch- 
ed from the base when not subacaulescent, the few branches 
rather rigidly upright; herbage very glaucous, glabrous: earlier 
leaves spatulate-linear, entire, those next succeeding 3-parted, 
the two lateral divisions entire, the terminal one trifid, all the 
lobes obtuse, those of the branches quinate and with few narrow 
divaricate divisions, the ultimate segments very acute : all the 
peduncles long, most of them scapiform: calyx not seen: 
corolla golden yellow, nearly rotate, 13 inches broad: pods 
slender, 2 and even 3 inches long; torus very small, and with 
about equally prominent cartilaginous ring (rather than rim) 
and hyaline inner margin : seeds small, spherical, blackish and 
with rather few and large reticulations. 
Eastern borders of the Mohave desert, California, and also on 
the other side of the Colorado River in Arizona, Norman C.

62. E. MEXICANA, Greene, Bull. Calif. Acad. i. 69, in part, 
excl. syn. Æ. Dougiasii, var. parvula. Stout subacaulescent 
annual 5 to 10 inches high, glabrous, glaucescent, at first with 
many rigidly erect scapiform peduncles of twice the height of 
the tuft of smallish and firm leaves: petioles broad and flat, 
about as long as the not large and coarsely dissected firm blades, 
ultimate segments of these not divergent, mostly oblong, 
acutish : calyx firm and opaque, the round-ovoid body surmoun- 
ted by a stout prominent taper-point, the whole 7 or 8 lines 
long: corolla rather light yellow, 1} inches broad, widely 
expanding : stigmas 4, not slender, very unequal ; pods stout, 24 
inches long; torus with narrow and cartilaginous rim and almost 
as prominent hyaline inner margin: seeds spherical, mucronate- 
apiculate, coarsely and faintly reticulate. 
This species was originally described from specimens of my 
own collecting on the upper Gila River plains, in 1880. I 
seen acres of the same in 1877 farther westward toward Tucson, 
and, supposing these plants of Arizona and even extreme 
western New Mexico to be one with the plant of the Rio Grande
