PENNELL: PLANTS OF SOUTHERN UNITED STATES 343 
wide, oblique-lanceolate, falcate, acuminate-mucronate on distal 
side, nearly glabrous, evidently ciliate, evidently nerved. Pedicel 
Sepals 10-11 mm. long, lanceolate, acuminate, puberulent. Petals 
10 mm. long, the anterior slightly exceeding the lateral. Stamens 
unequal. Legumes 4 cm. long, 4—4.5 mm. wide, strigose-hirsute, 
brown. Seeds twelve, 2-2.2 mm. long, oval. 
Type, “Texano-Mexicanum,” collected in fruit, Berlandter 
2036, in the herbarium of Columbia University at the New York 
Botanical Garden. 
Apparently differs from Chamaecrista calycioides (DC.) Greene 
of South America, with which it has been confused, by its fewer 
leaflets and solitary flowers; doubtless, when C. calycotdes is re- 
collected and fully described, by other characters. 
Besides the type collection, the precise locality of which is 
unrecorded, seen also from Cameron County, Texas, > May 8 
1900, Vernon Bailey 231, in the United States National Herbarium. 
3. Chamaecrista texana (Buckl.) Pennell, comb. nov. 
Cassia tecana Buckl. Proc. Acad. Nat. Sci. of Phila. 1861: 452.

herbarium of the Academy of Natural Sciences of Philadelphia. 
Perennial, from a rhizome. Stems ascending, 2-4 dm. long, 
puberulent in lines with ascending-incurved _ hairs. Stipules 
cordate-triangular, acuminate, slightly ridge-veined, puberulent, 
ciliate, 3-4 mm. long. Petioles 2-3 mm. long, puberulent with 
ascending-incurved hairs. Petiolar gland single, below proximal 
leaflets, sessile, rudimentary or mostly wanting. Leaflets ten to 
sixteen pairs, crowded, 6-8 mm. long, I mm. wide, elliptic-lanceo- 
late, acutish, pubescent, finely ciliate, strongly ridge-veined. 
Pedicel one, exceeding the subtending leaf, in fruit 30-50 mm. 
long, puberulent with incurved hairs. Sepals 7-8 mm. long, ovate, 
acute, finely appressed-puberulent. Petals 10-13 mm. long, the 
anterior slightly exceeding the laterals. Stamens ten, unequal, 
one or two longer; anthers 6 mm. long, yellow. Legumes 3-4 cm. 
long, 5 mm. wide, sparingly finely appressed-pubescent. Seeds 
eight. 
This has been identified as C. chamaecristoides and as C. pro- 
cumbens. 
C. chamaecristoides (Collad.) Greene, of South America, differs 
by its longer stouter stems, lanceolate stipules, slightly longer
