tropous, the base of the nucleus not having the same curva- 
ture as the teguments to constitute campylotropum. The 
want of a raphe isof no importance, indeed it may be asked, 
what in reality constitutes a compylitropous ovule.? Scarcely 
any part of the spatha is to be found in the fruit, even when 
the ovaria are beginning to be muricated, only a portion of 
the base is left, expanded and withered. 
Fruit densely erowded into an oblong areolate, prickly, 
muricate mass, the carpella sub-fleshy, muricate at the apex ; or 
exposed surface, angular and reddish where  appressed, 
surrounded by the flattened out perianthial leaves. Seed 
brownish, also angular and sub-muricate, outside pendulous, 
adhering especially towards the attachment to the fleshy parts 
of the fruit. Embryo conforable, radicle ? green, superior. 
Cotyledon white, friable, spongy, cellular; albumen in a gela- 
tinous state, and copious, but disappears in the mature seed. 
The parts are difficult to make out, without having seen the 
germination. 
The anthers look much like ѓо joined together, but the 
filament has only one central fascicle. 
The nucleus looks more like a sac containing granules 
than its usual cellular appearance, the foramen of the second 
tegument appears to be separable as a disc. 
The anatropalism of the ovule is more apparent after fecun- 
dation when the raphe becomes evident, and the inversion is 
complete: although considerable changes in form and size, 
have affected the two teguments, the nucleus remains much 
the same. 
The inner surface of the spathe, more especially the spadi- 
gerous part, is covered with white punctulate dots, the magni- 
fied depressed fundus is occupied by a stoma.
