tinct, somewhat reticulated cross-veins; petals none; stamens 35— 
65 ; filaments about 4 mm. long, flattened especially towards sum- 
mit; anthers about .5 mm. long; pistil solitary, sessile, about 2 
mm. long from base of ovary to summit of stigma, the style and 
stigma only slightly differentiated from the body of the ovary; 
ovary about .7 mm. in greatest transverse diameter, perfectly glab- 
rous, strongly compressed latterly, the sides irregularly oblong in 
outline; style slightly recurved, very short ; stigma minute ; pods 
8-10 (commonly 8) mm. long, very nearly sessile, strongly com- 
pressed laterally with sides irregular oblong, rounded towards apex 
on the dorsal face, rounded towards base on the ventral face, beaked 
by the short, blunt, hardened, apically somewhat enlarged, ascend- 
ing style which departs from the ventral side of the pod, just be- 
low the summit,at an angle of about 45°, pale green, walls thin, be- 
coming almost chartaceous, veins prominent, somewhat reticulated ; 
seeds usually 6, the four middle ones in two rows, the other two 
solitary, about 3 mm. long, about 1.5 mm. wide, lenticular, some- 
what flattened laterally, the sides oblong in outline, chestnut brown, 
covered with pale brown thin chaffy scales, especially along the 
edges where they form a well-developed deeply lacerate wing. 
In rich soil on a wooded bluff along the Tennessee River, 
near Knoxville, Tennessee, where it was collected in flower by the 
writer early in September, 1890, and 1891, and in fruit by Prof. A. 
Ruth in October, 1897. The large terminal leaflet suggests the 
leaf of Rubus odoratus L. 
A very distinct species of the Section Actimospora, most nearly 
allied to C. Americana Michx. though apparently slightly ap- 
proaching C. racemosa (L.) Nutt. (Section JZacrotys) in its solitary, 
sessile ovary, short style and partially two-ranked seeds. How- 
ever it is most abundantly distinguished from that species by its 
bibracteolate and much’ shorter pedicels, much fewer stamens with 
filaments one-half as long and anthers one-half as large, thin- 
walled pods about twice as large and chaff-covered, lenticular 
seeds. From C. Americana our plant -is differentiated by the fol- 
lowing characters: bractlets of pedicel always basal (in C- Amer 
cana usually borne near middle of pedicel); pubescence of inflor- 
escence rather sparse and straight, not glandular (in C. Americana 
dense, glandular, almost granular); petals none (in C. Americana 
the usually two, obovate, deeply lobed, cucullate petals are char- 
acteristic) ; shorter filaments (about 7 mm. long in CG. Americana); 
smaller anthers (7 mm. long in GC: Americana); sessile, solitary a 
ovary; much shorter and straighter style; much shorter beak to
