212 ON SOUTH-AMERICAN APOCYNACEJX. 
stricted at the mouth; segments oval, undulate, 3 lines long; disk of 5 oblong lobes, 
longer than the 2 ovaries; follicles 2, more than a foot long, subtorulose, sometimes 
conjoined at the apex. 
This plant, from its habit, bifid raceme, from the tube of its corolla constricted below 
the mouth, its disk, and its follicles conjoined at the apex, agrees with Temnadenia, and 
seems near 7. secundiflora. 
9. TEMNADENIA CoRDATA, nob.: Echites cordata, A. DC. l. c. p. 451. In Mexico (Mocin et Sessé, cum 
icon. ined.) : non vidi. 
A climbing species with flexible, terete, pilose branches ; leaves ovate, acuminate, cor- 
date at the base, ciliate, pilose, 3 in. long, 18-20 lines broad, on petioles 3 lines long; 
racemes axillary, shorter than the leaves, on a simple pilose peduncle bearing several 
alternate flowers spicately disposed on pedicels 3 lines long, supported by lanceolate 
bracteoles 1 line long; sepals lanceolate, acuminate, 3 lines long; corolla yellow ; tube 
cylindrieal, 8 lines long, narrowed a little below the middle, smooth in the mouth ; seg- 
ments ovate, acute, 3 lines long and broad; anthers conniving in a cone in the middle 
of the tube; style pilose ; stigma bilobed; disk of 5 free linear lobes. 
This plant bears all the characters of Temnadenia, and appears to be near T. secundi- 
flora and T. glaucescens from the same country.

Rio San Francisco (Gardner 1354) ; Rio San Franciseo (Blanchet 2865). 
Gardner's specimen from Penedo agrees well with Lindley's drawing. It is a handsome 
scandent plant, with flexuose puberulous branches, and axils 3 in. apart; leaves ovate, 
plicate and obsoletely eordate at the base, mucronately acute, velutinous on both sides, 
3-3$ in. long, 11-2 in. broad, on pubescent petioles 3 lines long; raceme lateral, 
pubescent, on a suddenly deflexed peduncle bare for the length of 1 in., thence densely 
many-flowered on pedicels 4-6 lines long; sepals acuminate, 2-3 lines long, with 5 inner 
lanceolate scales at the base of each; corolla 20 lines long, rose-coloured, with 5 stel- 
lular, yellow, oblong patches in the mouth; tube glabrous, constricted a little below the 
middle for 6 lines, 14 lines long; segments rhomboidally dolabriform, 6 lines long, 9 lines 
broad, rotate ; stamens inserted at the contraction of the tube; anthers coherent, acumi- 
nate, pilose dorsally, biaristate at the base; disk partly cleft into 5 oblong emarginate 
lobes, nearly as long as the 2 ovate ovaries.

l.c. p. 468: Dipladenia zanthostoma, Müll. l. c. p. 123 (excl. syn.). In Brasilia, prov. Sad Paulo: 
non vidi. 
Miller wrongly regarded this plant as identical with Dipladenia saponarie, A. DC. ; 
but it cannot belong that genus, as its disk shows. It has a short erect stem, with 
approximate leaves, which are oblong-lanceolate, contracted towards the base, acuminate,
