C. CoLLETIA PUNGENS. 
Fig. 1, a flower, nat. size. Fuj. 2, the same, magnified. Fig. 3, the same cut open, 
also magnified. Fig. 4, the stamens before dehiscence. Fig. 5, the same after dehiscence : 
both more magnified. 
D. COLLETIA SpAETIOIDES. 
Fig. 1, a flower cut open, magnified. Fig. 2, an anther before dehiscence, seen in front. 
Fig. 3, the same after dehiscence, seen in different positions : both more magnified. 
E. CoLLETIA CATAPHEACTA. 
Fig. 1, a flower, nat. size. Fig. 2, the same, magnified. Fig. 3, a longitudinal section 
of the same, also magnified. Fig. 4, stamens before dehiscence. Fig. 5, the same after 
dehiscence : both more magnified. 
F. CoLLETIA AEMATA. 
Fig. 1, a flower, magnified. Fig. 2, the same cut open, also magnified. Fig. 3, the 
stamens before dehiscence, seen in dififerent positions. Fig. 4, the pistil: both more 
magnified. 
Pl.VTE 36. A. CoLLETIA DUMOSA. 
Fig. 1, a flower, nat. size. Fig. 2, the same, magnified. Fig. 3, the same cut open, 
also maefnifieel. Fig. 4, a stamen before and after dehiscence, more magnified. Fig. 6 , a 
grain of pollen, highly magnified. Fig. 6, the pistil, magnified. Fig. 7, a 3-lobular 
capsule, seated in the circumscissed persistent cup of the calyx. Fig. 8, the three endocar- 
pal cells, with and without the enclosed seed, showing the manner of their dehiscence along 
the axile suture. Fig. 9, the persistent cup of the calyx, out of which the endocarpal cells 
have been thrown hy the elastic force of their dehiscence. Fig. 10, the seeds : all nat. size. 
Fig. 11, the same, seen in front, magnified. Fig. 12, the same, shown edgeways, where the 
basal chink is observed. Fig. 13, the same, seen from below, to show the basal chink. Fig. 14, 
the same, seen in front, with half of the outer cnistaceous tunic removed : it is along the 
line so cut away, and in the intermediate integument there shown, that we may perceive the 
peripheral cord of the raphe, which, originating in the basal chink, passes all round, crossing 
the apical chalaza, and returns to the point of its origin. Fig. 15, a longitudinal section of the 
intermediate integument, showing the inner integument entire, with its apical chalaza, and 
contracted at its base into a conical shape. Fig. 16, the peripheral cord of the raphe removed. 
Fig. 17, the inner integument removed. Fig. 18, the albumen. Fig. 19, a longitudinal 
section of the same across its smaller diameter, showing the enclosed embryo. Fig. 20, the 
emhryo removed, seen in front. Fig. 21, the same, seen sideways ; all equally magnified. 
B. CoLLETIA VePEECULA. 
Fig. 1, a leaf, 7iat. size. Fig. 2, the same, magnified. Fig. 3, a flower, nat. size. Fig. 4’ 
the same, magnified. Fig. 5, the calyx cut open. Fig. 6, the pistil : all magnified. Fig. 7’ 
stamens before and after dehiscence, seen in difierent positions, more magnified.
