P. cynanchoides, has a fairly wide distribution, for it is 
known from the neighbourhood of Rio in Brazil, from 
Paraguay, Uruguay and the north-west of the Argentine 
Republic. As in many other Bignoniads the terminal 
leaflet of the 3-foliolate leaves is replaced, in actively 
growing parts of the stem, by a 3-furcate tendril. The 
species thrives well in a temperate house under the con- 
ditions suitable for some of the species of Bignonia. 
Drscription.—Shrub, climbing; twigs slender, 4-angled 
and 6-ribbed; young shoots finely puberulous, soon 
glabrous. Leaves opposite, petioled, 3-foliolate, the end 
leaflet often replaced by a tendril with a 3-furcate tip ; 
petiole $-} in. long, finely pilose; petiolules similar and 
often longer; leaflets wide-ovate, acutely caudate- 
acuminate, base wide-cordate, 13-2 in. long, 14-13 in. 
wide, finely ciliolate, under a lens closely minutely 
lepidote beneath, very sparingly so above. Raceme 
terminal, few-flowered; pedicels about 2 in. long, 
2-bracteolate in the middle. Calyx cupular, truncate, 
minutely 5-toothed owing to the nerves being produced, 
excluding the teeth about 1 in. long, softly hairy outside, 
minutely closely lepidote, in the upper part finely sunk- 
glandular about the nerves. Corolla white, yellow within, __ 
tubular funnel-shaped, 13-2 in. long, curved throughout. 
limb spreading. Stamens 4, didynamous, the anterior the 
longer, all inserted, as is the staminode, about 1 in. above 
the base of the corolla; filaments thickened at the base, 
quite villous with moniliform hairs; anther-cells discrete, 
wide diverging, oblong, hardly 1 in. long. Ovary com- 
pressed-ellipsoid, shortly tomentellous, 2-locular, resting 
on a large cushion-like disk ; placentae 2 to a cell, many- 
ovuled, ovules many-seriate; style much contracted 
above the ovary, then thickened higher up; stigmatic 
lobes flat, leafy. Capsule oblong, narrowed to both ends, 
about 4 in. long, crowned with a 7-headed appendix, 
valves muriculate resembling a file. Seeds inserted 
transversely, flat, with a hyaline wing; body of the seed 
pyriform in outline.
