Scandent and epiphytic; stern loosely twining or looping 

 up to 7 ra above ground, crooked, subterete, flexible, 2.5 

 cm thick; the outer wood white, the inner one half reddish 

 to brown, soft, entirely without odor or taste; bark very 

 thick, latericius except the yelloYT?ish gray and quite smooth 

 or coarsely excrescent surface; main branches few from the 

 top only, 1.5 to 2.5 cm thick, crookedly rebranched, form- 

 ing tangled masses; twigs ascendingly curved, terete, striate, 

 even the young tips glabrous. Leaves numerous, verticellate, 

 rather crowded towards the ends of the twigs, coriaceous, 

 glabrous, much paler green beneath, apex strongly recurved, 

 obtusely rounded or gradually tapering and terminated by a 

 mucronate point, ascending, base obtuse or subpandurate, 

 otherwise nearly flat, curing grayish green beneath and near- 

 ly black above, exceedingly variable in size, the larger lam- 

 ina 12 cm long by 3.5 cm wide at the middle, linearly 

 oblong, edges entire, the smaller ones only one half as long 

 and one third as wide; midrib plane above, straight, prom- 

 inent and dirk brown when dry beneath; the lateral veins 

 in most of the smaller blades of 1 pair only and arising 

 subopposite from 5 to 15 mm above the base of the leaf, the 

 few very large blades with a second pair of lateral veins 

 arising at the base and running parallel with the margin, 

 the main pair extending clear into the apex; petiole 1.5 

 cm long, similar in color when dry, subterete and grooved 

 along the upper side. Inflorescence profuse, lateral and be- 

 low the foliage; stalks 1 to 3 cm long, arranged in vertic- 

 ellate clusters, umbel lately few branched from above the 

 middle, glabrous, pale green but turning brown when dry; 

 pedicels 4 to 7 mm long, very similar to the peduncle proper, 

 usually articulate below the middle; buds succulent, white,
