290 PITTONIA. 
19. EUPHORBIA BARTOLOMÆI. Annual, prostrate, the 
branches almost filiform and sparsely hirsute with very 
white hairs: leaves very small, round-ovate, entire, veinless, 
nearly equal-sided at base : stipules minute, setaceous, entire, 
eiliolate, apparently deciduous: flowers few, large for the 
plant: glands dark red-purple, transversely oblong or some- 
what reniform, adorned with a conspicuous dilated white or 
pale rose-colored appendage of which the margin is entire, 
erenate or sometimes deeply lobed : capsule pubescent : seed 
4 line long, almost white, angled rather sharply, strongly 
jus ose. 
The whole plant, apparently full grown, measures barely 
two inches from tip to tip of the prostrate branches. The 
species is related to E. setiloba and E. versicolor. 
13. Q(ENOTHERA CRASSIUSCULA. Annual,stoutish and a little 
succulent, a foot or two high with a few rigid virgate branches, 
glabrous and glaucescent: leaves 2 inches long, narrowly 
lanceolate, sinuately lobed or toothed : calyx-tube short cam- 
panulate: petals an inch long, light yellow: pods sessile, 
quadrangular, contorted : seeds linear-oblong, smooth, purple- 
dotted. 
The essential character of Nuttall’s genus Eulobus is the 
short calyx-tube lined with a disk. The present species is of 
that genus, if the genus be retained. So is also another 
Lower Californian plant of my own discovery, i. e., CE. crassi- 
folia (Bull. Calif. Acad. i. 188); but the view of M. Baillon, 
which places Eulobus in GZnothera, seems hardly contro- 
vertible, and the type-species must be named Œnothera Cali- 
fornica (Nutt.).
