This description has been drawn from a few fragments belong- 
ing to what appears to be a low shrub with straw-colored bark and 
short, almost fascicled branchlets. I have not seen any spines: 
but the apex of the peduncle seems to indicate a spinescent termi- 
nation.

PAROSELA THOMPSONAE 0. sp. 
Apparently alow shrub: branchlets short? clothed witha short, 
close, whitish, retrorse pubescence or tomentum and beset with 
scattered, somewhat elevated reddish glands, becoming glabrate 
with age; stipules caducous, not seen; petioles 3-5 mm. long, 
leaves about 1.5 cm. long, 5-7 or more foliolate; leaflets about 2 
mm. long, oblong, obtuse, acutish at the base, somewhat thick, 
minutely strigose-hirsute on both surfaces, margins revolute, with 
a few dark glands beneath ; racemes 3-4 cm. long, loosely-flowered, 
short-peduncled; bracts not seen, caducous; calyx 4 mm. long, 
glabrous, conspicuously 10-ribbed, with 1-3 round or oblong red 
glands between each rib below the sinus, the broadly triangular 
teeth ciliate, pubescent on the inner surface, shorter than the tube; 
corolla rose-purple, twice as long as the calyx, the petals with a 
few slender glands near the apex; legume and seeds not seen. 
A species with the calyx allied to that of Parosela maritima 
(Brandegee) from Lower California, but differing in the broad, 
ciliate, acutish or obtuse, short calyx-teeth and the very symmetri- 
.cal arrangement of the reddish glands on the ribs of the calyx- 
tube. The space between the two upper ribs is eglandulose, the 
next two spaces on either side have two glands eac 
the other, the remaining spaces having one glar
