c. Vertical convex, no other than the lateral points ; cavity 
contains a small pointless disc. 
E.— Vertical of still younger; u. anterior ; £. posterior. 
F.—Calyx anterior; «. convex, the infexed edge becomes 
the future placenta, 5. , 
G.—c. Upper stamens very large, lower petal much larger, 
actually veined, and petaliform, that is, more laminar. 
d. Very oblique rim of pistilla, point entire perhaps lead- 
ing to lateral separation. 
H.—e. Anterior convex. - 
f. Posterior. 
g. Outer. 
h. Posterior. 
Is the posterior tooth to be supposed to be inflexed, form- 
ing a vault over the young: genitalia ?' but this is extraor- 
dinary, for I see nothing like original distinction. 
I.—The placentze are distinct, the carpellary margins quite 
diverging almost from the point of inflection, they are very 
much lobed longitudinally. 'The whole, except the reflected 
marginal or laminar part, is covered with ovula; the lobes 
which are contiguous, fit into each other. 
Style—vascular fascicles 2, anterior and posterior: vessels 
of carpellary leaf marginal placentary. 
i. Vessel—ovules laxly cellular ; just turning, with a minute 
conical nucleus projecting, m. pth. : 
At expansion the foramen is exceedingly indistinct : and 
testa cells gorged with amylaceous granules. 
The early composition of the calyx, I certainly do not un- 
derstand. l : 
In other points it presents no great peculiarity. — . 
Examine other spathaceous calyces. The distinction 
of the placenta bears upon Dr. Wight's views of the struc- 
ture of Curcubitacez.|
