DESCRIPTION OF THE PLATES. 
Plate 100. — Odontocakta acupaeata. 
A portion of a branch of the female plant in fruit, and another of the male plant of 
Odonxocaeya HEDER^FOLiA in flowor. 
Fig. 1, a male flower on its pedicel, before expansion. Fig. 2, the three outer sepals. 
Fig. 3, the three intermediate sepals. Fig. 4, the three inner sepals. Fig. 5, the six 
sepals. Fig. 6, the stamens : all tiat. size. Fig. 7, one of the three outer sepals, mag- 
nified. Fig. 8, one of the three intermediate sepals. Fig. 9, one of the three inner 
sepals. Fig. 10, one of the six petals. Fig. 11, the six monadelphous stamens : all mag- 
nified to the same scale. Fig. 12, an anther on a portion of the filament, more magnified. 
Fig. 13, one of the three stipitate drupes. Fig. 14, a putamen deprived of its pericarp, 
and covered with dense thick tomentum, seen on the dorsal face. Fig. 15, the same, 
viewed sideways. Fig. 16, the same, shown on its ventral face. Fig. 17, the osseous 
putamen deprived of its tomentous coating, shown on its dorsal face. Fig. 18, a view of 
the same, on its ventral face : all nat. size. Fig. 19, dorsal view of the osseous putamen, 
with a slightly tuberculated surface, with three teeth at each extremity, magnified. Fig. 20, 
the same, shown on the ventral side, with a hollow condyle. Fig. 21, a transverse 
section of the putamen. Fig. 22, the seed, covered by its thin integument, showing the 
hollow space on the ventral side and the longitudinal raphe belonging to it, where it 
covers the ruminated albumen, and where it is fitted to the condyle. Fig. 23, the seed 
deprived of its integument, shown on its dorsal face, the thin stratum of simple albumen 
having been removed to show the relative size and position of the enclosed embryo. 
Fig. 24, a longitudinal section of the same, showing the position of the embryo within the 
albumen, which is thick and ruminated on the ventral side, and extremely thin and simple 
on the dorsal face. Fig. 25, the embryo extracted, seen edgeways. Fig. 26, the same, 
seen in front, showing the divergence of the cotyledons : all magnified to the same scale. 
Plate 101. — Khigiocakta racemifera. 
A portion of a branch of the female plant in fruit. 
Fig. 1, one of the three stipitate drupes, nat. size. Fig. 2, the putamen deprived of its 
pericarp, shown on its dorsal face. Fig. 3, the same, viewed edgeways. Fig. 4, the 
same, seen on its ventral face : all nat. size. Fig. 5, the putamen, densely echinated on 
its dorsal side with nail-headed erect spines. Fig. 6, the same, shown edgeways. Fig. 7, 
the same, seen on the ventral face, showing the long aperture leading into the very 
large hoUow condyle. Fig. 8, a longitudinal section of the same, showing the seminal 
cell and the large hollow chamber of the condyle : all magnified. Fig. 9, shows the shape 
of the spines, the short terminal hairs having been omitted, more magnified. Fig. 10, the 
seed extracted from its cell, covered hy its integument, showing, on the ventral side, the 
longitudinal raphe and its chalaza. Fig. 11, the same, viewed edgeways. Fu/. 12, the 
same, deprived of its integument, seen on the dorsal side, with the thin stratum of albumen 
removed, exhibiting the enclosed embryo with its divaricated cotyledons : all magnified 
to the same scale oafig. 5.
