DESCRIPTION OF THE PLATES. 
Plate 89. — Caltcocaepum Ltoni. 
A portion of the male plant in flower, and of the female plant in fruit. 
Fig. 1, a single male expanded flower on its pedicel, nat. size. Fig. 2, the same, mag- 
nified. Fig. 3, the exterior bracteiform sepals. Fig. 4, the six internal sepals in two 
alternate series. Fig. 5, the twelve stamens in four series, the six shorter ones opposite to 
the sepals, the other six longer and alternate with them : all equally magnified. Fig. 6, 
some of the same, seen in dilferent positions, more magnified. Fig. 7, a single female 
flower on its pedicel, nat. size. Fig. 8, the three outer sepals. Fig. 9, the three inner 
alternate sepfds. Fig. 10, the six petals, opposite to the sepals. Fig. 11, the six sterile 
stamens, opposite to the petals : all equally magnified. Fig. 12, one of the sterile sta- 
mens, more magnijled. Fig. 13, one of the three ovaries upon the gynajcium, from which 
the others have been removed, exhibiting some of the stamens, a petal, and a sepal, in 
order to show their relative positions round the base of the gynaecium. Fig. 14, the stigma, 
seen from above : both more magnified. Fig. 15, a fruit, nat. size. Fig. 16, the same, 
with half of the pericarp cut away transversely to show the enclosed putamen. Fig. 17, 
the putamen, seen on its dorsal side. Fig. 18, the same, seen on its ventral side, showing 
the hollow space between the teeth. Fig. 19, a side view of the same. Fig. 20, a trans- 
verse section of the same, showing the longitudinal carina which encloses the chord of 
uourishing-vessels on the ventral side. Fig. 21, a longitudinal section of the same, show- 
ing the line of the condyle and of the carina, to which the inner integument is attached’by 
the line of its raphe. Fig. 22, the seed, covered by its membranaceous integument, seen 
on its dorsal side. Fig. 23, the same, seen on its ventral side, faintly showing the line of 
the raphe. Fig. 24, the same, seen edgeways. Fig. 25, a longitudinal section of the 
same, showing the position of the embryo imbedded in the homogeneous albumen beneath 
its thin stratum on the dorsal side. Fig. 26, a transverse section of the same. Fig. 27, 
the same, with the thin stratum of albumen on the dorsal side removed to expose the 
cavity in which the embryo is imbedded. Fig. 28, the embryo removed, with the cotyle- 
dons further separated to show their form. 
Plate 90. — Jateoehiza calumba. 
A portion of a branch with male flowers, and an analysis of its fruit. 
Fig. 1, a flower before expansion, on its pedicel. Fig. 2, the same expanded. Fig. 3, 
the three outer sepals. Fig. 4, the three inner sepals. Fig. 5, the six petals. Fig. 6, 
the six free stamens : all nat. size. Fig. 7, the three outer sepals. Fig. 8, the three 
inner sepals. Fig. 9, the six petals. Fig. 10, the six stamens, in different positions, 
before and after dehiscence ; all magnified to the same scale. Fig. 11, one of the fruits, on 
the receptacle of the pedicel, from which the two others have been removed, nat. size. 
Fig. 12, the same, seen on its dorsal side. Fig. 13, the same, with half of the pericarp 
. removed. Fig. 14, the putamen, freed from its pericarp and covered with dense tomentum, 
seen on the dorsal side. Fig. 15, the same, seen laterally. Fig. 16, the same, seen on the 
ventral face, which is glabrous and flattened, and where it is concave about the condyle. 
Fig. 17, the same, shown on the dorsal face, with the upper moiety of the thick tomen- 
tous covering removed, and exposing the tuberculated surface of the putamen. Fig. 18, 
the putamen, on the dorsal side, with the whole of its pubescence removed. Fig. 19, a 
side view of the same. Fig. 20, the same, seen on its ventral face. Fig. 21, a longitu- 
dinal section of the shell of the putamen. Fig. 22, the seed extracted from the same.
