DESCRIPTION OF THE PLATES. 
Plate 85. — Ehretia elliptica. 
Fig. 1, the calyx, with the enclosed pistil. F\g. 2, the corolla expanded. Fig. 3, the 
same, cut open, showing the position of the stamens : all magnified. Fig. 4, a stamen, 
to show the mode of insertion of the filaments and of attachment of the anthers : more 
magnified. Fig. 5, the pistil, seated on a small disk, magnified as in Fig. 3. Fig. 6, a 
transverse section of the same, showing the development of ^e cells, the position of the 
ovules, and central columella, more magnified. Fig. 7, the fruit, in the persistent calyx, 
nat. size. Fig. 8, a transverse section of the same, showing two bilocular nucules en- 
closed within the pericarp. Fig. 9, external view of one of the nucules. Fig. 10, inner 
view of the same, partly hidden by the columella. Fig. 11, the membranaceous central 
columella. Fig. 12, transverse section of the same, with its cords of nourishing vessels 
passing through the apertures into the cells. Fig. 13, a transverse section of a nucule 
below the summit, showing the channels for the nourishing vessels leading to the funicles 
of the seeds. Fig. 14, another transverse section, across the middle, where the cells are 
entire. Fig. 15, a longitudinal section of the nucule in the line of the aperture leading 
into the cell. Fig. 16, a seed extracted. Figs. 17 & 18, the embryo, shown in front and 
sidewise : all magnified. Figs. 19 & 20, the same, more magnified. 
Plate 86. — Botjrreeia Havanensis. 
Fig.\, the calyx. Fig. 2, the corolla cut open: both magnified. Fig. 3, a stamen, 
seen before and behind, more magnified. Fig. 4, the calyx cut open, showing the pistil 
seated on its small disk, magmfied. Fig. 5, a transverse section of the ovary, showing 
the mode of placentation from the central columella, more magnified. Fig. 6, a fruit in 
the persistent calyx. Fig. 7, the pericarp cut longitudinally, to show two of the enclosed 
nucules. Fig. 8, two of the bigeminate nucules separated, seen on the ventral angle, 
showing the spurious cells into which the placentary vessels from the columella are re- 
ceived. Figs. 9 & 10, a lateral and dorsal view of the same: all nat. size. Fig. 11, a 
dorsal view of a nucule, showing the oblique lines of reticulated cells with which it is 
there covered. Fig. 12, a ventral view of the same, shoAving the position of the open 
vacuity. Figs. 13 & 14, lateral views of the same, upon its two angular sides. Fig. 15, 
a transverse section of the four nucules, showing the pseudo-cells filled with placentary 
matter, by which they adhere in pairs and are there attached to the central columella. 
Fig. 16, the central columellaj with its bundles of vessels leading into the pseudo-cells. 
Fig. 17, a nucule, seen from above, showing its peculiar dorsal cellules arranged in oblique 
longitudinal lines. Fig. 18, a transverse section of the same, showing the dorsal rigid 
cellules and the seminiferous cell and placentary vacuity placed within the osseous por- 
tion. Fig. 19, a longitudinal section of the same, showing the small channel leading 
from the summit of the pseudo-cell into the real cell, where the seed is attached by its 
funicle. Fig. 20, a seed, seen laterally, with its funicle and raphe. Fig. 21, a view of 
the same, on its ventral face. Fig. 22, the embryo, enclosed in albumen. Figs. 23 & 24, 
the embryo, seen sidewise and on its face : all equally magnified. 
Plate 87. — Crematomia Gtjildingiana. 
Fig. 1, the calyx. Fig. 2, the corolla. Fig. 3, the same, cut open, to show the auri- 
culated lobes of its border and the position of the stamens : all nat. size. Fig. 4, a sta- 
men. Fig. 5, an anther, seen before and behind : both magnified. Fig. 6, the calyx, cut
