8a. CHAMAECRISTA FASCICULATA 8 
Cassia Chamaecrista robusta Pollard, Bull. Torrey Club 21: 218.

Cassia robusta Pollard, l.c. 24: 150. 1897. 
Chamaecrista robusta Pollard; Heller, Cat. N. A. Pl. 2d ed. 5. 
1900. 
Stem stouter, 6-15 dm. tall, more or less densely hirsute above 
with spreading hairs. Stipules lanceolate-attenuate, 10-14 mm. 
long. Petioles hirsute-pubescent. Leaflets nine to eighteen 
pairs, 15-20 mm. long, 3-6 mm. wide. Bracteoles 4-6 mm. long. 
Pedicels 15-25 mm. long, hirsute with spreading hairs. Sepals 
hirsute on the midrib. Petals 15-20 mm. long. Legumes 5-7 
cm. long, 6-7 mm. wide, hirsute-pubescent. Otherwise as in the 
species. 
Moist to dry soil, more frequently in low ground, and most 
abundant on alluvial soil, southern Ohio to northern Florida, 
eastern Missouri and Louisiana. Throughout the lower Mississippi 
valley, mostly in alluvial soil; also pushing up into the valleys of 
the southern Alleghenies. In southern Louisiana, where I have 
collected it, seemingly quite distinct from C. fasciculata, but study 
of specimens shows a surprising number of intermediates.
