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 Convolvulus 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 dc 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. 



Root perennial, sublignescent, creeping, gi'owing 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 ilowering), smooth, upright, 



equal, twice shorter than the tube of the corolla, persistent : 



embracing the twice higher capsule after flowering. Corolla 



pui-plish red. Capsule subglobular, flattish underneath, 



smooth, surrounded by the calyx from the base to the 



middle, about the diameter of the thumb nail, bilocular 



quadri valvular. 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.
