GLOXINIA. Supra, vol. 3. fol. 213. 
G. tubiflora; caulescens, pubescens, foliis oblongis subacuminatis brevi- 
petiolatis subcrenatis, paniculà terminali, pedicellis elongatis, corolla 
subhypocrateriformi, tubo elongato sursum curvato, limbo patente, lobis

in Bot. Mag. t. 3971. 
This beautiful thing was raised in the Glasnevin garden, 
from seeds received from Mr. Tweedie of Buenos Ayres. Sir 
W. Hooker, however, suggests that it is really a native either 
of South Brazil or Paraguay. It isa charming greenhouse 
plant; its lovely snow-white flowers being very agreeably 
fragrant. 
What constitutes a Gesnera?—what a Gloxinia ?—what 
an Achimenes? According to the views of Martius and De 
Candolle, their differences are these : — 
Gersnera.—Calyx somewhat unequal. Corolla tubular, with 
five protuberances at its base, or an equal swelling all 
round. Anthers joined together when young. From 
two to five glands round the ovary. 
Gzoxinra.—Calyx equal. Corolla funnel-shaped or somewhat 
bell-shaped, inflated in the middle, protuberant on one 
side only of the base. Anthers joined together. Five 
glands round the ovary. 
Acuimenes.—Calyx equal. Corolla between tubular and 
funnel-shaped, protuberant on one side only of the base. 
Anthers separate. A ring round the ovary. 
Such being the case, the plant before us cannot be a Ges- 
nera, because its corolla is only protuberant on one side, and
