Oercooarpua nueeensia sp. nov 
Cercocarpus nuecenaia ap. nov. A small tree 3-4 m. tall; bark 
gray; branches and young twigs glabrous; petioles stramineous, 3-8 mm, long, 
projected to end of blade as a prominent midnerve, strigillose with black 
hairs; leaves oblanceolate to obovate, the blades mostly 3-4 cm, long, 1-2 cm, 
broad, cuneate, the base entire, coarsely toothed from above the middle, 
glabrate above, densely tomentulose beneath, prominently nerved below but the 
nerves scarcely impressed above, the lateral nerves usually opposite in pairs 
and at rather regular intervals along the midnerve, these pairs of lateral 
nerves 3-6, frequently 5, each ending at the apex of a leaf-tooth as an 
apiculation; flowers clustered, up to 10, frequently 5 or more; tube of the 
hypanthium 7-8 mm, long, the limb 3 mm, broad or less, strigillose; achenes 
about 1 jjaT, long, villous at base then glabrate or sparsely strigose until 
becoming villous above, or villous-strigose throughout; style in fruit densely 
plumose, curved or bent, leas 5 cm, long or less, usually 3,5-4,5 cm, long. 
Type specimen. No, 20888, was collected November 3, 1936, at the 
head of the West Fork of the Nueces River, about 14|- miles southeast of 
Rocksprings, Edwards County, Texas, In using the key to the North American 
C. species of CeMcarpus given in North American Flora this plant traces out to 
r C, a.^genteus ^db,, from which it differs in the denticulation of the foliage 
being acute instead of crenate, in the upper surfaces of the leaf being glabrate 
instead of densely pilose, in the flowers being clustered instead of being 
solitary or in pairs, in the tube of the hypj^nthium being strigillose instead cL 
of silky, the limb being 3 mra, or less instead of 6-7 mm, broad, and in the 
style in fruit b^ng less than 5 cm. long instead of 6-7 cm. long. This plant 
agrees in more pjarticulars with 0, Traskiae Eastw., a species of Cat/lina 
Island, California, but in one or more respects it is markedly distinct from 
that species. This one tree is the only plant Ceroocarpus the writer has 
ever seen on thej iSdwards Plateau. Efforts will'be made to locate other 
specimens of thi^ species in the canyons of the plateau.
