what cordate, obtuse leaves, with a central rib, which is_ 
remarkably swollen below, and three slender ones on each 
side near the margin: petioles terete, almost pellucid, 
jointed within ; their bases surrounded with oblong, mem-_ 
branous, convolute stipules. Peduncles elongated, single- — 
flowered, rising from among the petioles and internally — 
jointed like them. Calyx of three, oblong, patent, green — 
eaves. Corolla of three, very large obovato-rotundate, — 
very obtuse, slightly concave, spreading petals, twice the — 
length of the calyx, of a delicate primrose colour, faintly — 
striated, rather a deep yellow at the base. Stamens nu- — 
merous: Filaments deep, bluish-purple, subulate ; outer — 
ones sterile: Anthers linear, ‘purple: Pollen yellow. Pistils — 
six, erect, linear-oblong, standing close together, attenuat- . 
ed into a rather slender style: Stigma purple, velvety, from — 
the extremity decurrent for some way down on the inside. 
Some time ago, I received from Mr. Twerente of Buenos - 
apie specimens of this plant, gathered in pools or ditches — 
of fresh water, near that city. Seeds were likewise sent 
from the same source to the Botanic Garden of Liverpool, 
where the plants raised from them were successfully treated — 
in the aquarium by Messrs. Surpnerps, and the handsome — 
and delicate flowers burst open in great perfection in April, — 
1833. They are, however, like those of Hyprocnaris Mor- 
sus Rane, of our country, very fagacious, and but for We — 
greatest care on the part of Mr. Henry Suepuerp, 1 ¢ 
not have received them in a state fit for drawing. ExeeP’ 
in the absence of the sterile stamens around the fertile ones, | 
I do not see how the Hyprocieys Commersoni of Rich ABD 
1, c. p. 368, t. 18, differs from this plant, and it is a0 jnha- 
eeu of the same country. I possess what I take to 
e same plant, gathered abundantly in British Guian@ by 
C. S. Parker, Esq., inhabiting the same places with the 
beautiful Pontepersa azurea, Bot, Mag. t. 2932.
