8a. Chamaecrista fasciculata /3 



Cassia Chamaecrista rohusta Pollard, Bull. Torrey Club 21:218.

Cassia rohusta Pollard, I.e. 24: 150. 1897. 



Chamaecrista robiista Pollard; Heller, Cat. N. A. PI. 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.
