covering, without any membranaceous wing, and with only the 
sharp angular edges produced by the strong mutual pressure of 
growth : had they been relieved from this pressure, their shape 
would have been nearly spherical. A longitudinal section of 
one of these seeds shows, within the thick coriaceous testa, a 
nearly circular space, which is divided by a broad septum into 
two equal complete cells : this septum is entire throughout, ex- 
cept a very small linear foramen in the eentre, which aperture 
is filled by the central radicle of the embryo, while the space of 
the two cells is occupied by the cotyledonary portion, which is 
divided into four equal lobes, as in the instances before described : 
these lobes are thick and fleshy, plano-convex, in contiguous 
pairs, and are united by the central short terete radicle, the ex- 
tremity of which is centrifugal, pointing to the large broad basal 
hilum. 
In Spathodea campanulata the 4-celled capsule is represented 
by Palisot de Beauvois* as having numerous orbicular lenti- 
cular seeds, with a narrow wing, all packed together in a hori- 
zontal position, as in Calampelis (not parallel to the dissepiment), 
and attached to the inner angle of each cell by a linear hilum 
along its truncated margin, and this margin is somewhat in- 
duplicated within the testa. The embryo is shown to be formed 
of four cotyledonary lobes attached to the apex of the terete radicle 
equal to them in length, as in Argylia ; they are not spread out 
in opposite pairs, as in that genus, but are folded and parallelly 
superposed upon one another, their outer margins lying in pairs 
right and left of the induplicature of the testa, the cross-section 
of its internal space being thus hippocrepiform : the radicle is 
placed in contiguity to this semiseptum, so that the edges of 
all the four cotyledonary lobes are thus accumbent upon it 
and close to the line of the raphe. A similar induplicature 
of the cotyledonary lobes is figured in DelesserPs ‘ leones ’ (v. 
tab. 93 b), in Kigelia, a genus of Crescentiacece. 
In Stereospermum chelonoides (taking Dr. Wight’s analytical 
figures t for guidance, the correctness of which I am able to 
verify), the integuments of the seed are inflected, by a deep 
plicature, into the dorsal face, and thus produce a transverse 
semiseptum within the discoidal portion, in a contrary direction 
to that of Anemoptegma : this protrudes into the middle of the 
cavity of the crustaceous integument. The cotyledons are cleft 
almost to the base, and are folded as in the last instance, so that 
their four lobes lie with their external edges in pairs on each 
side of the semiseptum, and in this manner are lodged in the 
incomplete cells so formed : the internal edges of the lobes thus
