Lysiloma Watsont Rose. Cofradia. 
Lystloma sp. Nearly glabrous, with large semicordate stipules 
that persist. Collected only in flower. Near the plant collected 
by Pringle in Rincon Mts., Arizona, 1884. 
Bauhinia (Paz/etia) chlorantha. A bush 2-3 m. high, the 
sulcate stems finely pubescent; leaves orbicular in circumscrip- 
tion, cordate, bilobed one-quarter of their length, the lobes 
rounded, pubescent on the 7-9 nerves beneath, 4-5 cm. long and 
wide; petioles 15 mm. long, pubescent; the stipules are slightly re- 
curved prickles 5 mm. long and 4 mm. broad or less at the base; 
flowers in pairs in a terminal raceme or from the upper axils; 
peduncles 2 cm. long; calyx 10-12 cm. long, finely pubescent; 
Stamens united near the base, 5 fertile, with narrow, pointed 
anthers 18 mm. long, the others with as long filaments and 
shorter, linear-lanceolate, rudimentary anthers; petals narrowly 
linear, not half as long as the stamens: pistil of the open flower 
14-15 cm. long, exceeding the filaments; stipe of the pubescent 
Ovary 7-8 cm. long: legume pubescent, 20-22 cm. long, 15 mm. 
wide, acuminate, plane. 
This species is near &. leptopetala DC., but differs from it as 
figured in Calques des Dess. FI, Mex., in having rounded lobes 
to the 9-nerved leaf, larger flowers and longer petals. The flowers 
of B. chlorantha have nearly the color of the surrounding vege- 
tation. Collected in the vicinity of Culiacan. 
Krameria prostrata. The hirsute stems prostrate, sparingly 
branched, 3-4 dm. long; larger leaves linear-lanceolate, nearly 
sessile, 2 cm. long, 2-3 mm. wide, hirsute beneath; flowers on 
2-bracted peduncles 1 cm. long; sepals 1 cm. long; the three 
upper petals united three-fourths their length; stamens united 
near their bases; capsule globose, white silky-pubescent, 8 mm. 
in diameter; the spines subulate, 1 mm. long. 
Collected at Cofradia. The slender stems of this species are 
not woody and the plant spreads flat upon the ground amongst 
other vegetation and but for the purple sepals would not be con- 
spicuous.
