tion inconspicuous. Racemes shorter than their leaves, their 

 peduncles slender, about as long as the petioles, the flower 

 branches loosely disposed, sub-opposite, divaricately spreading, 

 the 3-flowered branches about as long as the flowers, slender, 

 sharply angled. Perigone divided to the base, the lower por- 

 tion of the lobes erect, a little shorter than the reflexed, linear 

 greenish-yellow upper portion. Stamens shorter than perigone, 

 the filaments a little shorter than the oval anther. Style slen- 

 der, the stigma capitate. 



Cotaiia, Bolivia, 2450 M. (Buchtien, No. 3158.) 



Aetanthus ovalis. 



Glabrous, the branchlets short and stout, terete, greenish, 

 strongly wrinkled in drying. Leaves 5 to 8 cm. long, 2 to 5 cm. 

 broad, oval, abruptly contracted into a short petiole-like base, 

 rounded at the summit, entire, thick, revolute, roughened on 

 both surfaces with fine papilla-like wrinkles, sub-5-nerved by 

 two pairs of strong secondaries originating near the base of the 

 midrib. Peduncles clustered at the ends of the branchlets, the 

 bracts very short, broader than long, blunt. Flowers (young 

 and unopened), 7 cm. long, straight, very slender, the middle 

 third dilated to about twice the thickness of the other portion. 

 Calyx-tube 2 or 3 mm. long and nearly as broad, purple, the 

 whitish margin truncate, with very small acute teeth. Sta- 

 mens attached at the base of the upper third of the corolla, 

 where the latter is pilose. Filaments very short, the anthers 

 extending to the summit of the corolla, slightly sagittate at the 

 base, attenuate at the summit. 



"In damp forest. Sierra del Libano, 6,000 feet May 18.- 

 On a high tree, the flowers bright-red. Grows to 5 feet long, 

 with pendent branches." (Herbert H. Smith, Colombia,

Dendrophthora stricta. 



Glabrous. Stems much-branched, the ultimate tranches 

 to 8 cm. long, very slender, the internodes 2 to 2.5 cm. long, 

 more or less quadrilateral and with a sharp nerve between the 

 angles. Leaves i to 2.5 cm. long, i to 2 mm. wide, linear, 

 obtuse or acutish, entire, thick, the midrib prominent beneath. 

 Spikes to 2 cm. long, including the sharply angled peduncle^ 

 which is a third of the length, very slender, many flowered, the 

 pair of bracts at the base of the inflorescence 1.5 mm. broad. 

 Flower 2 mm. long and nearly as broad, lightly immersed, the 

 petals ovate, acute, not keeled, thickish, the calyx annular, 

 narrow, obscurely lobed. Rudimentary stamens present on 

 some petals. Stigma very small. Berry 5 mm. broad, 3 mm. 

 high, light-brown.
