always loose and campaiiulate, and usually truncate. It differs principally 

 in the fruit, the capsule being broad ovate. The species here noted is a ten- 

 dril-climbing shrub with ash-colored, striate, glabrous stems, hispid on the 

 summits of the youngest branches. Leaves bi-tri-foliolate ; petioles 10-15 

 mm. long, striate beneath, hispid and canaliculate above ; petiolules 5 or 6 

 nim. long, striate and glabrous beneath, canaliculate and hispid above like 

 the petioles, the hairs dense and running up the thick midrib and lowest 

 nerves of the upper surface of the leaflets. Leaflets coriaceous, entire, ellip- 

 tical, very glabrous except as above stated, nerves prominent beneath, nar- 

 rowed at both ends, mucronate at the apex, i3-6 cm. long, 1-3 cm. wide. 

 Flowers 1-3, axillary, on striate, glabrous, or slightly pubescent pedicels 8-10 

 inm. long. Calyx glabrous, nerveless, or obscurely nerved at the base, loosely 

 campanulate, truncate, with a membranous margin, 7 or 8 mm. long, yellowish 

 in color. Corolla yellow, darker colored at base, glabrous, in fundi buli form, 

 the tube slender, 4 or 5 cm. long, spreading about 2 cm. across the lobes when 

 expanded, the lobes large and rounded, somewhat ringent. Fruit not seen.

Climbing by tendrils over shrubs and trees. Stems smooth, 

 hexagonal, the branches fuscous-downy. Leaves trifoliolate ; leaf- 

 lets ovate or orbicular, cordate, downy. Calyx downy, truncate or 

 5-dentate, scarcely \ as long as the corolla. Corolla yellow, very

 Fruit a large, flattish, 2-celled, 2-valved capsule, densely echinate, 

 10-12 cm. long by 4 or 5 cm. broad, filled with broadly winged 

 seeds, the wings silvery, delicate membranous and transparent. 

 This is a fine liana, the flowers showy and the large echinate fruit 

 very conspicuous.

Ampliilopliiuiii paniculatum, H. B. K., Nov. Gen., iii, 149. 



Between Yiila Rica and Escoba (446); Asuncion (753). 



A tendril climber distinguished by having a double calyx, the 

 outer spreading, with a sub-5-lobed, reflexed border, and the inner 

 appressed and bilabiate. Corolla bilabiate, with a short tube about 

 2 cm. long, ventricose at the throat, upper lip galeate, bilobate, the 

 lower 3-lobate. Fruit very different from that of 158, in company 

 with which it grows, being a thick, subligneous, lenticular capsule,
