Ifranchlets hearing numerous coarse, slightly elevat(!d glands, densely 
pubescent with minute, mostly ai)prcssed hairs; petioles stout, densely 
glandular, always more than half as long as the leallets and often e(jual- 
ing them ; leaflets commonly 8-11), rarely (> or 7, l-M or randy 4 cm. long, of 
nearly uniform width throughont, glabrous, or sparsely pubescent with 
very minute, appressed hairs on the upper surface, the margins slightly 
revolute, remotely crenulate; sepals obtuse, truncate, or retu.se, ciliate; 
petals 7-8 mm. long; capsule (> imn. high, copiously pubescent with 
slender, appre.s.sed or slightly spreading hairs. 
Guadalupe IMountains of western Texas ( lA Havard, Agnes Chase), to 
southern New IMexico (San Andreas IMonntains, J. IT. Gant 87, Pope 
Exped., E. 0. Wooton), and northern Chihuahua i Bigelov:). 
The specimens upon which this species was based were said to have 
come from the Organ Mountains, New Mexico; probably they came 
instead from the San Andreas Range, which lies just to the north of the 
Organs and is .separated from them oidy hi^ a high pass. Capt. Pope’s 
expedition is known to have followed the road which leads over the pass. 
The shrub is often abundant, l)nt it is known to occur in oidy a few 
localities, in all of wdiich conditions are similar. The IMexican name 
is given as sorillo, a term which is applied to other mendoers of the 
family, as for instance, to a species oi Xanthoxyhim in Sinaloa and Tepic, 
Mexico.

Branchlets stout, bearing numerous low glands, densely pubescent with 
slender spreading hairs; petioles one-tifth to one-third as long as the 
leaflets, densely hirtellous; leaflets 3-5, 1.2-4 cm. long, 2-4 mm. wide, 
conspicuously widest at or above tlie middle, narrowed toward the base, 
rounded at the apex and often emarginate, densely hirtellous, the margins 
usually ))lane, broadly repand-deuticulate, the lateral leaflets often much 
reduced; pedicels 1-1.5 cm. long, densely hirtellous; ovary densely hirsute; 
flowers and fruit not seen. 
Type in the U. S. National TTerbarium, no. 15,0(12, collected by the 
.Mexican Boundary Survey, no. 14(3. On the same sheet are two branches 
of C. dumosa, distributed under the same nunbDer. According to the 
Botany of the .Afexican Boundary Survey,* this numher doubtless in¬ 
cludes specimens from northern (’hihuahua and otluu’s from the “ west¬ 
ern slope of the Sierra del Pajarito, Sonora.” It is ])rohal)le that the type 
of C. mollis is from the latter locality.
