DESCRIPTION OF THE PLATES. 
covered by its integument. Fig. 23, a side view of the same. Fig. 24, the same, shown 
on its ventral face, with the cavity where it is attached to the condyle, and showing the 
fissures of the ruminated albumen. Fig. 25, a longitudinal section of the same, showing 
the albumen thick and ruminated on the ventral side, and very thin and homogeneous on 
the opposite face, beneath which the embryo is imbedded. Fig. 26, a transverse section 
of the same, to show more clearly the same structure. Fig. 27, the embryo removed, 
with the divaricated cotyledons in their natural position, and the small superior radicle : 
all nat. size. 
Plate 91. — Tinospoba coedifolia. 
A portion of a branch of the male plant in flower, and of a female plant in fruit. 
Fig. 1, a male flower expanded, nat. size. Fig. 2, the three outer sepals. Fig. 3, the 
three inner sepals. Fig. 4, the six petals, embracing the base of the six stamens, shown in 
different positions : all equally magnified. Fig. 5, a female flower expanded, tiat. size. 
Fig. 6, the three outer sepals. Fig. 7, the three inner sepals. Fig. 8, the six petals, 
with the six sterile stamens seated at their base : all equally magnified. Fig. 9, a female 
flower on its bracteated pedicel, showing the relative positions of the sepals, petals, sta- 
mens, and ovaries, magnified. Fig. 10, the same, with the sepals, petals, and stamens 
removed, showing the three ovaries seated upon the gynsecium, and leaving a petal and 
stamen at its base to indicate their relative positions. Fig. 11, a longitudinal section of 
an ovary, showing the form of the stigma and the mode of attachment «f the ovule, more 
magnified. Fig. 12, a fruit, nat. size. Fig. 13, the putamen, with the pericarp removed, 
seen on its dorsal face, showing the marginal suture by which it may, without difficulty, 
be split into two valves. Fig. 14, the same, seen on its ventral face, showing the broad 
aperture leading into the hollow condyle. Fig. 15, a lateral view of the putamen : all 
nat. size. Fig. 16, a drupe, magnified. Fig. 17, the putamen seen on its dorsal face, 
showing its tubercular surface. Fig. 18, the same, viewed laterally. Fig. 19, the same, 
on its ventral face. Fig. 20, a longitudinal section of the putamen, showing the hollow 
condyle and the aperture leading into it. Fig. 21, a transverse section of the same. 
Fig. 22, the seed, covered by its very thin integument, shown on its dorsal face. Fig. 23. 
a view of the same upon its ventral face, showing the large hollow that is fitted round the 
condyle and the longitudinal line of raphe by which it is attached to it, and the trans- 
versaUy corrugated surface of the inner ruminated portion of the albumen. Fig. 24, a 
lateral view of the seed. Fig. 25, a longitudinal section of the same, showing the trans- 
verse furrows of the ruminated inner side of the albumen and the external thin plate of 
simple albumen which covers the imbedded embryo. Fig. 26, a transverse section of the 
same. Fig. 27, the albumen, with its external thin plate of albumen removed to show 
the shape and position of the enclosed embryo. Fig. 28, the embryo removed, showing 
the divaricated cotyledons and the radicle : all magnified to the same scale. 
Plate 92. — Chasmathera dependens. 
A portion of a branch of the male plant in flower, and of the female plant in fruit. 
Fig. 1, a flower on its pedicel, before expansion, nat. size. Fig. 2, the three outer 
sepals. Fig. 3, the three inner sepals, smooth internally and pilose outside, with ciliated 
margins. Fig. 4, the three inner petals. Fig. 5, the three outer petals. Fig. 6, a trans- 
verse section of a petal, showing its inner prominent longitudinal keel. Fig. 7, the six
