the tropics, as the Potato is in Europe. In our collections, 
the beauty of the flowers has been the chief recommenda- 
tion of these plants: but there are, perhaps, few, if any, 
that can equal in this respect the one now under considera- 
tion ; for the opportunity of figuring which, we are indebted 
to Joun Aticarp, Esq. of Stratford Green, Essex, in whose 
stove and that of his neighbour, Miss Loxtey, plants have 
been in flower the last two months. Mr. Aricarp informs 
us that the seeds were collected by Mr. Samuen Ricuarpson, 
(an officer in the Anglo-Mexican Mining Association) in the 
province of Guanaxuato, in Mexico, and were by him pre- 
sented to J. D. Powxes, Esq. of Stamford Hill, who liber- 
ally distributed them. 
Descr. A twining, glabrous plant, with rounded, herba+ 
ceous branches, tinged with purple. Leaves alternate, mem- 
branous, palish-green, truly cordate, with a deep and broad 
sinus at the base, shortly but sharply acuminated, quite 
entire, wavy on the surface, much veined, situated on petioles 
about equal to them in length. Peduncles axillary, bear- 
ing three to four flowers, somewhat racemose, the pedicels 
thickened. Calyx five-partite, the segments small, erect, 
and appressed, linear-subulate, brownish-purple with a pale 
almost white margin. Corolla, in bud, white, with the limb a 
of a rich lake red, which, when the flower is fully expanded, 
becomes of a fine purplish blue, with five angles and five 
plice, the angles mucronate. Filaments unequal in height, 
inserted at the base of the tube, hairy at the base. Anthers 
eblong, yellow. Germenoblong. Style filiform. Stigma . 
two-lobed.

Segments taken away to show the Germen.
