petioles follow nearly the same course and rate as the inter- 
nodes, but the two opposite petioles did not move together. 
Lastly, the tendrils, besides being carried about by the 
revolving petioles, themselves move: spontaneously. ‘Then, 
with regard to the branches of the tendrils, they are sensitive 
on all sides, bending in about 10 minutes after being rubbed, 
or after coming in contact with a support; and after such 
contact several branches might be seen slowly to lift themselves 
up, change their positions, and again come into contact with 
the supporting surface. The object of this latter movement 
is to bring the double hooks at the ends of the branches, 
which naturally face in all directions, into contact with the 
wood, lastly, if the tendrils come into contact with a 
slender object, the sensitive nature of their branches (on 
being touched) close to the little hooks, causes them to curl 
round and clasp it. — 
Descr. A slender climber, glabrous, or with a scant 
scabrous pubescence, chiefly on the branchlets, petioles and 
inflorescence ; trunk with corky bark; branches acutely 
angled. Leaves opposite, bipinnate, the main petiole stiff 
and angular, the secondary more flexuous, and often ending 
in dichotomously branched filiform circinnate tendrils ; 
leaflets few, alternate, petiolate, one-fourth to three-fourths of 
an inch long, ovate-cordate or orbicular, obtuse, more or less 
oblique, entire or lobed. Racemes four to six inches long, 
drooping; bracts small, ovate, green; pedicels secund, a 
quarter to half an inch long. lowers an inch and a half 
long. Calyx-tube rounded at the base, rather inflated ; lobes 
triangular, erect. Corolla tubular, ventricose above the calyx 
on one side, suddenly contracted at the orifice; limb very 
short, revolute, 5-lobed. Anthers with divaricating lobes and 
glandular connective. Ovary oblong; style slender, stigmas 
two, diverging. Capsule pendulous, an inch and a half long, 
elongate-ovoid or ellipsoid, suddenly contracted into a stipes, 
coriaceous, wrinkled, 2-valved; placentas narrow, covered 
with imbricating seeds in many rows. Seeds one-twelfth of 
an inch in diameter, including the broad circular wing, which 
is notched at the base.—J. D. H.
