"A twining vine, to 6 or 8 feet, with white flowers; moder- 

 ately common in dry thickets and forests below 2,000 feet, 

 July-August or later. Collected near Bonda, 150 feet, July; 

 the fruit in August." (Herbert H. Smith, Colombia, No. 

 1676.) 



Tassadia recurva. 



Glabrous. Stems slender, terete, the intemodes about half 

 as long as the leaves. Petioles 5 or 6 mm. long, slender, chan- 

 nelled, the blades 4 to 7 cm. long, 2 to 2.5 cm. broad, lanceolate 

 with rounded base and somewhat abruptly acuminate apiculate 

 summit, thickish, deep-green, the venation slender, sparse and 

 obscure. Panicles axillary and terminal, elongated, slender, 

 sparsely branched and flowered, the branches and inflorescence 

 subtended by small, subulate, brown bractlets, the flowers 5 to 

 lo-fascicled or umbelled, the pedicels slender, about twice as 

 long as the flowers, which are 3 mm. broad, when fully expanded. 

 Calyx-lobes about equalling the saucer-shaped tube, ovate, 

 obtuse, each bearing a linear scale within, near the base. Cor- 

 olla deeply parted, the lobes lance-linear, strongly recurved, 

 obtusish, a dark spot near, the base. Dorsum of the narrow 

 lobes of the crown keel-like. Appendages of the anthers ovate, 

 hyaline. Corpuscle linear-oblong, the pollinia narrowly ovoid, 

 pendulous on long slender filaments. 



"Twining to 20 feet. Rare in mountain forest, 1,500 to 

 3,500 feet. Collected at Las Partidas, 3,500 feet, March 15, 

 and Minca, 2,000 feet, June i. (Herbert H. Smith, Colombia,

 nearly straight; Peduncles 3 to 5 mm. long, and about equaling 

 the pedicels, or a little longer, the flowers 5 to 10. Calyx 

 parted to the base, the lobes i mm. long, ovate, acute. Corolla 

 rotate, 6 mm. long, parted nearly to the base, thickish, the lobes 

 lance-ovate, obtusish, tomentellate within. Crown adnate to 

 the base of the stamens, twice the length of the stamens, tne 

 scales hyaline, nearly distinct, the inner two-thirds the length 

 of the outer, acuniinate, the outer long-attenuate. Corpuscle
