188 Plants Collected in Paraguay. 



jflelloa populifolia (D.C.), Britton. 

 Bignonia ]>opuli/olia, D.C., Prod., ix, 159. 



Asuncion (1536). October. 



A tendril climber, wiih large bifoliolate, rounded leaves and 

 clusters of large, showy 3^ellow flowers. Calyx much inflated, 

 spathaceous, the fissure oblique, running to an aristate point on 

 one side. Corolla infundibuliform, with a swelling tube and flaring, 

 rounded lobes, often 6 or 7 cm. in length. Stem stout, warty, the 

 branches striate. This plant is very conspicuous when in flower, 

 and would make a beautiful object in gardens, though the Asun- 

 cionites never seem to have taken it for that purpose. 



Ciispidaria pterocarpa (Cham.), D.C., Prod., ix, 178. 



Caballero (596). January. 



A genus closely allied to Bignonia, but differing in its tetrapter- 

 ous fruit, hirsute anthers, and uniformly cuspidate-lobed calyx, from 

 which the generic name is derived by DeCandolle. The species 

 here noted climbs over large trees without tendrils, so far as I 

 could see, with bi-tri-foliolate leaves, and lax, terminal racemes of 

 showy funnel-shaped, yellow flowers. It is very ambitious, like all 

 the South America lianas, and climbs to the very tops of the trees, 

 and throws out its clusters of conspicuous flowers above their heads. 



Adenocalymna nitidum. Mart, in D.C. Prod., ix, 200. 



Asuncion (19t). November-December. =Gibertll06. 



Stem glabrous, striate, cinereous-pubescent on the inflorescence. 

 Leaves bifoliolate; petioles and petiolules about equal, canaliculate. 

 Leaflets rigid, glabrous, shining above, elliptical, rounded at the 

 base, acute and cuspidate at the apex, 6-12 cm. long, 3-4 cm. wide. 

 Calyx marked by 2-17 black, cup-shaped glands, which also occur 

 occasionally on the bracteoles. Corolla 6 or 7 cm. in length, bright 

 yellow, often shading off into white towards the summit, with a 

 ventricose tube and a large flaring border having 5 broad, rounded, 

 subequal lobes. Fruit a heavy, drooping capsule, 2-celled, some- 

 what tetragonous when young, becoming at maturity almost cylin- 

 drical and very hard, 20 cm. long and 2 cm. wide, usually 2 on a 

 peduncle. 



Anemopaegma flaTum^ Morong, n. sp. 



A genus very similar to Bignonia in flowers, leaves, and stems, differing in 

 liaving a thick pulvinate disk, stamens and styles always included, the calyx
