puberulous; the axils are 14 in. apart; leaves ovate or ovate-oblong, roundish at the 
base, and subcordate,. subacuminate, coriaceous, dark green above, corrugulate, gla- 
brous, with slender immersed nerves, yellowish opake beneath, granulated midrib and 
nerves prominulent and pubescent, without apparent veins, 2-2} in. long, 1-1} in. 
broad, on stoutish pubescent petioles 2-3 lines long ; racemés short, axillary, ¿ in. long, 
on à very short peduncle, bearing 2-3 alternate approximate flowers; pedicels very 
short, bracteolated; sepals obtusely oblong, pilose outside; corolla with a short tube; 
segments spathulately oblong, longer than the tube, with simple dextrorse convolution ; 
stamens inserted near the base of the tube; anthers acuminate, with 2 basal aristate 
prongs ; disk of 5 free, erect lobes, nearly as long as the 2 ovaries; 2 erect, terete follicles, 
pilose, 33 in. long, the sutural margins introflexed and seminiferous; seeds oblong, com- 
pressed, with a small central hilum, furnished dorsally above the middle with dense 
erect hairs extending far beyond the summit.

A climbing species, near the preceding, but easily distinguished by the very dilated 
nodes of its branches, which are 3 in. (sometimes 2 in.) apart; the branches are reddish 
brown and softly pubescent; leaves oblong-ovate, rounded at the base, gradually acute 
above the middle, rigidly chartaceous, with revolute margins, pale green above, sulcate 
along the nerves, the younger ones sparsely hirsute with hairs globose at the base, pallidly 
flavid beneath, very opake, subrugulous, midrib and nerves very prominent, and patently 
hirsute, 11-21 in. long, 8-14 in. broad, on stoutish, recurved, rigidly hirsute petioles 
2-4 lines long; flowers geminate or solitary in the axils on patently pilose pedicels 
3 lines long, each bearing 3 alternate acute bracteoles; sepals acute, pale green, pubes- 
cent, 3 lines long, 14 line broad; corolla glabrous, with a cylindrical tube 2] lines long; 
segments ovate, 4 lines long, 24 lines broad, with simple dextrorse convolution; rest as 
in the preceding species; 2 follicles, parallelly erect, linear, compressed, subtorulose, 
flavidly pubescent, when not quite ripe 3 in. long, 14 line broad, often conjoined at 
the apex. :

A low shrub, with several procumbent or scandent ramose hirsute branches, about
