and the position of the stamens. Fig. 7, a segment of the corolla, seen on the inner and outer sides. 
Fig. 8, a stamen : all natural size. Fig. 9, a stamen seen before and behind, magnified. Fig. 10, a 
pollen grain, highly magnified. Fig. 11, the disk, ovary, style, clavuncle, and stigmata, natural size. 
Fig. 12, the disk and enclosed ovary, magnified. Fig. 13, a transverse section of the 2-celled ovary. 
Fig. 14, the style, clavuncle, and stigmata: magnified. Fig. 15, the fruit, copied from Aublet (not 
reversed), supported by the lacerated calyx and pedicel, natural size. 
Pare III. 
A. Aspidosperma Gomesianum. Fig. 1, a portion of a branch, with its expanded terminal panicle. Fig. 2, 
a flower. Fig. 3, the corolla: all natural size. Fig. 5, the corolla, with sinistrorse convolution. 
Fig. 6, the same cut open, showing the position of the stamens, Fig. 7, a stamen, Fig. 8, calyx with 
the sepals thrown back, to show the ovaries and style : all magnified. Fig. 10, a follicle. Fig. 11, the 
same, seen on its edge in the act of dehiscence. Fig. 12, a longitudinal section of the same, showing 
each seed suspended from the summit by a slender funicle attached peltately to the central hilum of 
the scutcheon of the winged seeds. Fig. 13, the eight parallel seeds, with the funicles of four averse 
from the half of the pericarp on one side, and the other four also averse from the opposite half. 
Fig. 14, a seed membranaceously winged round the scutcheon, with the central hilum attached to the 
funicle. Fig. 15, the nucleus extracted from the scutcheon. Fig. 16, a longitudinal section of the 
nucleus, showing the heterotropous embryo enclosed in the albumen. 
B. Thyroma sessiliflora. Fig. 1, portion of the plant, with its axillary panicle in flower. Fig. 2, the 
same in fruit: natural size. Fig. 3, a flower and portion of the peduncle, magnified. Fig. 4, a flower, 
more magnified. Fig. 5, the calyx and style. Fig. 6, the corolla cut open, showing the sinistrorse 
convolution and the five scales opposite the segment and the position of the stamens. Fig. 7, astamen, 
shown before and behind: still more magnified. Fig. 8, the tubular disk enclosing two ovaries. 
Fig. 9, the style, clavuncle, and stigmata: much magnified. Fig. 10, the very compressed flat follicle. 
Fig. 11, the same, seen on its edge, showing the marginal suture. Fig. 12, the same in the act of 
dehiscence, showing the four seeds in two series, both upper and lower, appended to the marginal 
replum by as many horizontal flat funicles attached to the central hilum of each scutcheon upon 
the face furthest from the pericarp. Fig. 13, a transverse section of the same. Fig. 15, the 
dexter seed of the lower row, with an inferior seutcheon, showing the horizontal funicle upon 
its inner face. Figs. 16 and 17, the sinister and dexter seeds of the upper row, with superior 
scutcheons, showing that in both cases their funicles, facing one another, are turned to the middle 
of the cell of the pericarp. Fig. 18, the embryo, as placed in the two last figures, seen on its face 
and on its edge: all natural size. 
Pare IV. 
A. Thevetia calophylla. Fig. 1, portion of a branch. Fig. 2, the corolla cut open, showing the position 
of the stamens: twice magnified. Fig. 3, a stamen, more magnified. Fig. 4, a profile view of the 
stamen and its attachment to the corolla, with the faucial appendage. Fig. 5, the calyx, with the 
sepals thrown back to show the inner basal scales, the disk, ovaries, and style: much magnified. 
Fig. 6, the style, clavuncle, and stigmata, more magnified. Fig.7, a transverse section of the 2-celled
