206 Plants from Sinaloa, Mexico. [ZOE 
nately 8-10 nerved; margins entire and bearing few or many 
short-stipitate glands; base of the blade furnished with 4-8 long- 
stipitate glands; petiole % as long as the blade, sparingly stellate 
pubescent; stipules linear-lanceolate, 2-3 mm. long bearing 
longer stipitate glands: racemes moncecious, 3-6 cm. long with 
2-7 pistillate flowers below: bracts Jinear, bearing long stipitate 
glands: pistillate flowers on pedicels 2-3 mm. long, apetalous; 
sepals 5, linear-lanceolate, 8 mm. long, stellate-pubescent, stipi- 
tate-glandular onthe margins; styles 3 mm. long, 4-cleft to below 
the middle; ovary densely stellate-pubescent: staminate flowers 
on pedicels 1 mm. long; stamens about 12; sepals ovate-acumi- 
nate, stellate-pubescent, 1.5 mm. long; petals twice as long, 
spatulate; receptacle pilose; capsule shorter than the calyx lobes, 
stellate-pubescent. 
This plant grows on the low, level lands about Yerba Buena 
near Altata. 
It is very fragrant when living and the same odor is noticed 
when boiling the dried plant. The stipitate glands are much 
like those of C. ciliato-glandulosus. 
Jatropha canescens Muell Yerba Buena, Altata. 
Jatropha purpurea Rose. Culiacan. 
Jatropha vernicosa. A bush 2-4 meters high, glabrous throughout; 
dicecious: leaves ovate-acuminate, cordate, 5-7 cm. long, 3-5 cm. wide, 
dark green and shining, pinnately veined, the margin bearing numer- 
ous sessile glands; petioles 3-7 cm. long; stipules represented by 
sessile glands; pistillate flowers usually solitary, terminating the 
branches; pedicels 2-3 cm. long; calyx lobes 5, distinct to the base, 
foliaceous, ovate, 5mm. long, margined with sessile glands, glutinous 
and shining; petals ligulate, equalling the calyx, white or sometimes 
with a tinge of purple, distinct; disk entire; styles the same number 
as cells of the ovary (two with my specimens), distinct to the base and 
divided to the middle: capsule subglobose, 2 cm. in diameter: stami- 
nate flowers cymose-cory mbose, the peduncles shorter than the leaves; 
calyx lobes elliptical, slightly united at base; stamens 10; glands of 
the disk five. 
Common at middle elevations of the Cape Region mountains of 
Baja California. In general habit much resembling /. canescens of the 
same region, a species there also dicecious. I have plants of both 
species in cultivation and they thrive well in their new habitat. The - 
construction of the flower of /. vernicosa shows that it belongs to 
§ Adenoropium of Benth. & Hook. My specimens of the Cape Region 
incorrectly named /. cordaita belong to this new species. Specimens 
of /. canescens from Altata are moncecious.
