the secondaries 8 or 10 pairs : panicles I dm. long, loosely- 

 flowered, stoutly peduncled : pedicels slender, .5—1 cm. long : calyx 

 6—7 mm. long, 5-6 mm. broad, campanulate, the margin truncate, 

 almost entire: corolla (color?) 5 cm. long, the tube campanulate,

Junction of Rivers Beni and Madre de Dios, August, 1886 (no. 



1142). No. 1210 (Beni River, July, 1886) may be the same. Its 



n leaves are biternate, the leaflets ovate, 1— 1. 5 dm. long, 4-6.5 cm. 



broad, the flowers large and distinctly yellow. 



Bignonia Rusbyi Britton, sp. nov.

 stout, costate : leaflets 2, the petiolules nearly equaling the petiole, 

 blades .75-1.25 dm. long, 3-5 cm. broad, oblong, blunt to 

 rounded at the base, abruptly very short-pointed and obtuse at the 

 apex, thickish, the venation lightly impressed above, prominent 

 underneath, the secondaries 8-10 pairs : panicle 1 dm. long or 

 less, shortly and stoutly peduncled, densely flowered : pedicels .5-

Finely puberulent : branches terete, finely costate : petioles about 

 t cm. long : leaflets 2, the petiolules about 1 cm. long, stoutish, 

 sub terete: blades .5-1 cm. long, 2-3 cm. broad, lance-oblong, 

 rounded at the base, acuminate and acute at the apex, entire, thin 

 but rigid, bright-green, punctate, the venation inconspicuous above, 

 prominent underneath, the secondaries about 6 pairs, strongly as- 

 cending and incurved, their upper portions sinuous near the mar- 

 gin before communicating, connected by the straightish tertiaries, 

 the lowest pair elongated so as to make the leaf somewhat 3 -ner- 

 ved ; racemes very short, densely several- flowered, short-peduncled, 

 lanceolate-bracted : pedicels about 5 mm. long, slender: calyx 

 campanulate, 7 mm. long and somewhat broader, lobed about one 

 third of the way, the lobes broad, rounded at the apex, the sinuses 

 acute ; corolla-tube nearly 3 cm. long, the lower fourth contracted,
