species, and in combining the two under a new specific title. 
It seems to be a very general plant in the sands of the tro- 
pical shores of Asia and America. Mr. Brown found it in 
New Holland. It may be looked upon as holding the same 
place in the tropical regions, as Convorvunus Soldanella 
does in the extratropical portion of our hemisphere. It 
is a rank growing creeping plant, and takes up too much | 
room to be generally cultivated in our hothouses, where 
we believe it is seldom met with. We have to thank 
the Comtesse de Vandes for a specimen, which flowered 
this summer in her botanical establishment at Bayswater. 
The South American plant, usually described as 3-flowered, 
was introduced by Mr. Mark Catesby in 1726; the East 
Indian plant usually described as one-flowered by Mons. 
Richard in 1770. ‘There is considerable variation in the size 
and outline of the foliage of the plants; but this is equally 
the case in several other species of the genus. ah ee 
Root perennial, sublignescent, creeping, growing to a 
great length, often to 12 feet, of the thickness of a man’s 
thumb. Stems generally 3 or 4 feet high, but sometimes 
twice the height of a man, trailing along the ground, with 
few branches, round, smooth. Leaves alternate, petioled, 
nearly orbicular, with a quite entire edge, emarginately 
retuse, very smooth, thick, close, about as large as the palm 
of the hand. Petioles usually longer than the blade, smooth, 
generally red. Glands 2, at the insertion of the leaf, on 
each side of the petiole, linear or almost as if from a red 
cleft. Peduncles axillary, solitary, longer than the petioles, 
many-flowered ; middle pedicle simple, longer, 1-2 inches in 
length; side ones subdivided. Leaflets of the calyx ovate 
with a small point (obtuse after flowering), smooth, upright, 
equal, twice shorter than the tube of the corolla, persistent : 
embracing the twice higher capsule after flowering. Corolla 
purplish red. Capsule subglobular, flattish underneath, 
smooth, surrounded by the calyx from the base to the 
middle, about the diameter of the thumb nail, bilocular 
‘quadrivalyular. Partition thin, membranous. Seeds 2 in 
each cell, ovate, large, convex on the outer side, angular on - 
the inner, brown, villous, with angles more thickly villous.
