DESCRIPTION OF THE PLATES. 
a female flower on its pedicel, before expansion, nat. size. Fig. 12, one of tbe six 
sepals, magnified. Fig. 13, one of the six petals. Fig. 14, the three ovaries seated on 
the gynaecium, which is surrounded at its base by the six small sterile stamens. Fig. 15, 
the six sterile stamens : all magnified to the same scale. Fig. 16, the three ovaries, 
more magnified. Fig. 17, one of the three drupes, the two others having fallen from the 
receptacle, nat. size. Fig. 18, the putamen deprived of its pericarp, seen on its dorsal 
face. Fig. 19, the same, seen on its ventral face: both nat. size. Fig. 20, the same, 
shown on its ventral face, showing the central hollow of the condyle, edged with teeth, 
with a peripheral series of teeth round the outer margin, and the longitudinal carinal 
suture down the middle, magnified. Fig. 21, the same, seen on the ventral face, showing 
the toothed periphery, the toothed carinal suture, and two intermediate lines of prominent 
teeth. Fig. 22, the same, viewed laterally. Fig. 23, a longitudinal section of the puta- 
men, showing the external hollow surface of the condyle, with its internal surface convex 
within the cell, and continuously surrounded by the dorsal and ventral, toothed, prominent 
sutural line. Fig. 24, the seed extracted, showing on its ventral face a corresponding 
hollow and the longitudinal raphe by which it adheres to the inner surface of the condyle. 
Fig. 25, a dorsal view of the same, vrith the outer surface removed to show the enclosed 
embryo with divergent cotyledons, seated in the middle of finely ruminated albumen : 
this structure was only observed after the text in p. 57 was printed. Fig. 26, a longitu- 
dinal section of the same, showing the position of the embryo : all magnified to the 
same scale. 
Plate 99. — Aspldocaeya tjvifera. 
A portion of a branch of the male plant in flower, and another of the female plant in 
fruit. 
Fig. 1, the twelve sepals, in four series. Fig. 2, the six petals. Fig. 3, the mona- 
delphous stamens : cdl nat. size. Fig. 4, the three external sepals. Fig. 5, the three 
sepals of the next series. Fig. 6, the three sepals of the following series. Fig. 7, the 
three inner sepals. Fig. 8, the six petals. Fig. 9, the six anthers, fixed on the margin 
of a peltiform connective, supported upon a central monadelphous column : all eqvMlly 
magnified. Fig. 10, an anther before dehiscence. Fig. 11, the same after dehiscence: 
both more magnified. Fig. 12, one of the three stipitated drupes. Fig. 13, the putamen 
deprived of its pericarp, shown on its dorsal face. Fig. 14, the same, seen edgeways. 
Fig. 15, the same, on its ventral face : all nat. size. Fig. 16, the putamen, showing the 
prominent keel on its dorsal face. Fig. 17, a longitudinal section of the same, showing 
the aperture through which the nourishing-vessels pass to form the short funicle attached 
to the raphe. Fig. 18, a transverse section of the putamen, indicating the keel on its 
dorsal face. Fig. 19, a lateral view of the seed, with the funicle on the ventral side in 
connexion with the raphe. Fig. 20, a view of the same on its ventral face, showing the 
longitudinal raphe and basal chalaza. Fig. 21, a lateral view of the same, deprived of its 
integument. Fig. 22, a longitudinal section of the same, showing the position of the 
embryo below the thin surface of the albumen on its dorsal face. Fig. 23, the same, seen 
on its dorsal face, with the thin stratum of the albumen removed, showing the relative 
size and position of the embryo, with its divergent cotyledons, all equally magnified.
