530 STERCULIACES. 
Petals convolute unguis distant. 
Its close affinity with Heteropyxis is now manifest, the 
points of difference are the tubular calyx, the undivided pe- 
tals all the filaments autheriferous, and 5-phalageal anthers 
with a marginal cell dehiscing longitudinally, and 5-celled 
ova ° 
The direction of development is precisely the same as 
indicated by the smallest lateral anthers of each phalanx, and 
the largest and longest towards the centre, and the concavi- 
ty of the base of the phalanx shews that the former are ex- 
ternal as regards the axis, the latter, internal. 
In both, the filaments only have l vasc. fasc. up to a cer- 
tain amount of composition, they then have two or three. 
The larger stature of the inner stamens which certainly is 
opposed to what might be expected, is characteristic also of 
Malvacee, but none of the plants of that family have such a 
tendency to composition of stamens, and it becomes worthy 
of enquiry whether the tubus staminifer of Malvacez is due 
to cohesion of the filaments below, or whether it is the basis 
from which they spring. 
Keenig’s description and figure are not altogether correct, 
though he gives materials for a more correct, generic defini- 
tion than has found its way into DeCand?s Prodromus, the 
differences which affect the degree of solution of the involucel, 
the base of the calyx, its distance from the insertion of the 
involucra, the size of the filaments and style, and their degree 
of stiffness, may originate from the extensive cultivation to 
which this species has been subjected. 
Konig has not understood the structure of the anthers, 
these he describes as mesenteriform. 
DeCand.’s definition contains two remarkable errors, Onè 
the calyx is naked, the other, petals smaller than the calyx. 
. A transverse section shews the nectaria to consist of hori- 
zontally attached bed of papillæ.
