- This plant is quite distinct from the Bignonia unguis, Linn. ; accord- 
ing to Velloz's drawing, the internodes of the branches are 2 to 24 
inches apart, the petiole is 24 inches, the petiolules 5 lines, the cirrhus 
3% lines long, with short “hooked claws; the leaflets are 22 to 4 
ае long, 14 to 2% inches broad; the basal bract of 2 lines below 
the peduncle of 2 lia, which. supports 2 pedicels 6 lines long, or 
when it bears a single flower, it is 6 to 8 lines long; the calyx 
6 lines long, 10 lines diameter in the mouth; the tube of the corolla 
18 lines long, with segments 5. lines diameter; stamens arched in 
pairs, with anther-lobes extremely divaricated; ovary seated in a 
fleshy pulvinate cup. Mr. Weir's Specimen agrees with the above, 
but as » is а very young and undeveloped shoot, before the ар- 
pearance of any inflorescence, its identity cannot be certified; its 
braiiehtet i is terete and striated, with internodes 13 to 2? inches apart, 
eaves ecirrhose. and conjugate, the 2 intermediate pairs 
3-foliolate, and the last pair in a very y oung state conjugated with a 
9-fid cirrhus; the petiole of the lower pair is 12 inch, the petiolules 
5 lines, the leaflets 22$ to 3 inches long, 13 inch broad. И it be 
not absolutely identical with Velloz's ar es near the same be: 
lity, it is a closely allied species, and agrees in the size, shape and 
nervation of the leaflets, and of its 9-04 « е with D. ferruginea 
from the Uruguay. 
The genus Doxantha constitutes a well-marked group of climbing 
plants, many of which are known, the type being the Bignonia unguis, 
Linn. Their slender stems are little branched, they have mostly conju- 
gate, small, submembranaceous leaves; with a very short cirrhus 
terminated by 3 hooked forks, like cat's claws. "They have large showy ` 
flowers of a dark violet or yellowish hue, generally solitary in the 
superior axils, or upon a short peduncle, bearing 2 or 3 pedicellated 
flowers, or in very rare cases more than that number. e calyx is 
laxly campaniform, with a sinuous margin, which is more or less 
expanded and plicated ; the corolla is large, with a short constriction at 
its base, thence expanding widely upwards, with a broad open mouth, 
and a border of 5 lobes, 2 of which are somewhat smaller and more 
reflected; the included stamens are didynamous, arching towards each 
other in pairs, with extremely divaricated anther-lobes. The capsule is 
very long, siliquiform, with 2 flat linear valves, somewhat thicker on 
the margins, and a filiform replum that separates from the thin parallel 
dissepiment, along the margins of which are attached, in a single series, 
many extremely flat and elongated seeds, which haye a dark, broad, 
opaque wing, the extreme tips of which are hyaline, The genus comes 
close to Distictis in its habit and appearance, but differs in several 
features, especially 1 in its far more elongated capsule, and the uniserial 
attachment of its seeds, In most of the species, the leaves are marked 
beneath with minute imbedded glands, distinguishable under a lens, 
but these are not pellucid as in Stizophyllum. Sometimes the hooks of 
the claws are transformed into radicant shoots or glands, by which they
