This plant, which I found in 1837, is evidently identical with Müller's variety above 
cited; but it is a species extremely different from that of Velloz. Its very twining 
branches are extremely slender, scarcely 4 line thick, dilated at the axils, the lower 
ones being 3 in., the upper ones 15-2 in. apart, and furnished with 2 almost obsolete 
stipules; its oblong-ovate leaves are cordate at the base, contracted near the summit 
into à long, narrow, acute acumen, submembranaceous, pale green above, with slender 
immersed nerves, yellowish-opake beneath, with immersed reddish nerves, 1-13 in. long, 
6-9 lines broad, on petioles 3—4 lines long; raceme lateral, on a peduncle 1 in. long, 
slender, bearing at its apex 6-8 flowers alternately approximate, on pedicels 5 lines 
long, with a small bracteole at their base; sepals ovate, acute, 1 line long; tube of 
corolla (still in bud) cylindrical below, swelling above, 12 lines long; segments 6 lines 
long, with dextrorse convolution ; stamens inserted in the constriction of the tube, on a 
pilose ring ; anthers acuminate, dorsally subhispid, with 2 narrow, parallel, obtuse basal 
prongs; disk of 5 fleshy truncated connate lobes, as long as the 2 conical ovaries; 
fructiferous peduncle 1 in. long; pedicel 9 lines long; follicles 2, arcuate and conjoined 
at the summit, 3 in. long, 2 line thick; seeds 2 lines long, with a spreading, reddish- 
yellow coma 34 lines long. 
A drawing of this plant, in flower and in fruit, is given in Plate XXXI.

My specimen quite agrees with Müller's drawing, which was probably made from 
Riedel’s specimen. It is a climbing species, very near the preceding, with very slender, 
funiform, diehotomous branches, the axils being 13-2 in. apart, and bearing 2 minute 
stipules; the leaves are oblong, rounded at the base, suddenly narrowed at the summit 
into a much longer acute acumen, chartaceous, with subrevolute margins, pale-green 
above, with reddish immersed fine nerves, paler and yellowish-opake beneath, with a 
prominent yellow midrib, the nerves scarcely visible, 13-2 in. long, 8-10 lines broad, on 
petioles 5-6 lines long; fructiferous peduncle 21 in. long, with the cicatrices of few 
flowers above; elongated pedicel 1 in. long; follicles arcuate, divaricate, striate, sub-
