Eeyes, 1,000 feet, H. H. Rushij, October 25, 1921 {no. 1311). 

 A low and slender shrub. 



Bauhinia vulpina 



Hirsute throughout except on the upper leaf-surface, with 

 divergent strongly ferruginous hairs. Branchlets short, rather 

 stout, divaricate, coarsely angled. Stipules not seen. Ten- 

 drils stout, simple. Petioles 2 to 3 cm. long, slender. Blades 

 3 to 6 cm. long, 2 to 3.5 cm. wide, cordate with acute or acutish 

 sinus, which is broader than deep. Leaf bifid nearly half way, 

 the sinus open, very acute, aristate; thin, subglabrous on the 

 upper surface, except toward the base, each half 4-nerved, the 

 venation prominent on both surfaces, strongly, finely and crook- 

 edly anastomosing-. Racemes terminating the branchlets, long- 

 peduncled, the flowering portion dense, conical, about as broad as 

 long, mostly recurved. Bracts nearly 1 cm. long, ovate, acu- 

 minate, several-dentate Avith aristate teeth, meml3ranaceous, 

 strongly veined. Pedicel a little shorter than the calyx. Bract- 

 let linear, about as long as the campanulate calyx-tul3e, which is 

 brown, strongly 15-nerved, contracted at the mouth, where it is 

 pilose internally, the 5 teeth shorter than the tube, equal, green, 

 thin, ovate, acute, 1- or 3-nerved. Petals about 8 mm. long, ovate, 

 obtusish, thick, strongly veined, pilose externally and at the base 

 internally, the stout claw aliout a third the length of the limb. 

 Stamens 10, very unequal, much shorter than the petals, the fila- 

 ments stout and rigid, the anthers ovoid, short and broad. Ovary 

 ovoid, obtuse, densely coarse-pilose. Immature pod 7 cm. long, 

 2.5 cm. broad, strongly flattened, oblong, apparently 2-seeded, the 

 summit rounded, the margin thickened and hirsute, especially 

 toward the summit, and tipped with the short, thick, hirsute 

 style.
