rounded and deeply cordate at the base, acute at the summit, with a bullate surface 
above, and much reticulated divergent nerves, canescently tomentous below, with reddish 
prominent nerves, furnished at the base of the midrib adjoining the petiole with several 
subulate glands; they are 3-42 in. long (including the sinus 6-9 lines deep), 2-3j in. 
broad, on stoutish petioles 4-6 lines long; panicle lateral, longer than the leaves, 
6-7-flowered ; flowers albescent, on alternate pedicels 6 lines apart, with a small basal 
bract ; sepals acute, 4-5 lines long, submembranaceous, each with a row of lanceolate 
inner basal scales; tube of corolla 23 in. long, cylindrical, somewhat contracted in the 
middle, funnel-shaped above, with a border of 5 obliquely oblong segments, 13 lines 
long, 6 lines broad, having a large internal spot at their base; stamens inserted in a 
pilose ring in the contraction of the tube; disk of 5 free lobes, half the length of the . 
2 pointed oblong ovaries. 
This species is placed in Prestonia by Bentham and Hooker (Gen. ii. p. 709) on account 
of the supposed 5 large scales in the mouth of the corolla, as figured by Ruiz and Pavon ; 
but these are mere discoloured spots, or they would have been otherwise described.

A slender climbing plant, with axils about 13 in. apart, having 4 intrapetiolar stipules 
truncate and acutely emarginate ; its opposite oblong leaves are suddenly acute at their 
summit, slightly cordate at their base, where they have 5 fleshy acutely subulate glands 
at the base of the midrib (3 central, 2 lateral); they are glabrous, with about 10 pairs of 
divaricate nerves, 23-3 in. long (including the sinus, scarcely more than 1 line deep), 
1313 in. broad, on petioles 4 lines long; racemes solitary in the axils or geminate, 
9-10-flowered ; peduncle 3 lines long; pedicels often geminate, of a purple colour, 
twisted, 6 lines long, with 3 bractlets at the base;' sepals oblong, pointed, 3-4 lines long, 
with many internal lanceolate basal scales; corolla white inside, purplish outside, its 
tube cylindrical, contracted in the middle, and again narrowed in the mouth, 1 in. long; 
segments subreflected, ovate, inequilateral, with a long, narrow, horizontal expansion ; 
stamens cohering, inserted in the contraction of the tube; disk of 5 free fleshy lobes, 
half the length of the subulately oblong ovaries ; follicles 2, slender, terete, subadherent 
at the apex, nearly straight, near 7 in. long, 2 lines thick ; seeds slender, 6 lines long, 
crowned by a fulvous coma 4 lines long.

A climbing species having angular subvillous branchlets, with internodes 33-44 in. 
apart, and there furnished with many glandular stipules ; leaves ovate, subcordate at the 
base, acute at the summit, glabrous above, villous about the sinus, midrib and neryes 
prominent and villous below, and there furnished at the base of the midrib (at its junc- 
tion with the petiole) with many subulate fleshy glands, 33-4 in long, 2-23 in. broad, on 
villous petioles 9-11 lines long; racemes lateral, long, pendent on a Weer, peduncle 
bare at its base for the length of 4 in., bearing 3 alternate, somewhat remote flowers on
