rounded and deeply cordate at the base, acute at the summit, with a buUate 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 3-4f in. long (iacludiag the sinus 6-9 lines deep), 2-3f in. 

 broad, on stoutish petioles 4-6 lines long ; panicle lateral, longer than the leaves, 

 6-7-fl.owered ; flowers albescent, on alternate pedicels 6 lines apart, with a small basal 

 bract ; sepals acute, 4-6 lines long, submembranaoeous, each with a row of lanceolate 

 inner basal scales ; tube of corolla 2^ ia. long, cylindrical, somewhat contracted in the 

 middle, funnel-shaped above, with a border of 5 obliquely oblong segments, 13 Hues 

 long, 6 liues 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. Frestonia by Bentham and Hooker (Gen. ii. p. 709) on account 

 of the supposed 5 large scales in the mouth of the coroUa, as figured by Euiz and Pavon ; 

 but these are mere discoloured spots, or they would have been otherwise described.

A slender climbing plant, with axils about IJ in. apart, haviug 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 6 fleshy acutely subulate glands 

 at the base of the midrib (3 central, 2 lateral) ; they are glabrous, with about 10 pairs of 

 divaricate nerves, 2|-3 in. long (including the sinus, scarcely more than 1 line deep), 

 l|_li in. broad, on petioles 4 lines long ; racemes solitary in the axils or geminate, 

 9_10-flowered ; peduncle 3 lines long ; pedicels often gemiaate, 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 ; foUicles 2, slender, terete, subadherent 

 at the apex, nearly straight, near 7 ia. long, 2 lines thick ; seeds slender, 6 liaes long, 

 crowned by a fulvous coma 4 lines long.

 A climbing species having angular subvillous branchlets, with internodes 3^-4J 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 nerves 

 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, 3|-4 in long, 2-2^ in. broad, on 

 villous petioles 9-11 lines long ; racemes lateral, long, pendent on a slender peduncle 

 bare at its base for the length of 4 in., bearing 3 alternate, somewhat remote flowers on
