DESCRIPTION OF THE PLATES. 
D. Details of Feangula vulgaris. 
Fig. 1, a seed, magnified, covered by a hard crustaceous entire coating (an arillus), which 
has only a small pervious opening at the base, that being the point of its attachment to the 
placenta. Fig. 2, the same, seen sideways. Fig. 3, a longitudinal section of the same, 
showing that the outer crustaceous shell is quite free all round the circumference of the 
second membranaceous integument, exeept for a short space near the basal aperture on 
one side. Fig. 4, a view of the same, with the outer crustaceous coating removed : here 
is seen the simple cord of the raphe, which is quite peripheral, consisting of numerous 
spiral vessels imbedded in the integument, and which, in its course roimd the margin, 
crosses over the apical chalaza : one extremity of this raphe is lost in the small point of 
attachment of the integument to the ariUus, the other passes out of the hilar aperture to 
communicate with the placenta. Fig. 5, a longitudinal section of the albumen, enclosing 
the embryo. Fig. 6, the embryo extracted, seen on one face. Fig. 7, the same, seen 
edgeways: all equally magnified. 
E. Details of Ziztphus Sinensis. 
Fig. 1, a ripe drupe. Fig. 2, a longitudinal section of the same, showing its enclosed 
fusiform nut. Fig. 3, the nut extracted. Fig. 4, a transverse section of the same bilocular 
osseous nut, each cell containing a single erect seed. Fig. 5, a longitudinal section of the 
same, with the seeds in situ : each seed is seated in a small cup with a crenulate margin. 
Fig. 6, the seed extracted, seen edgeways. Fig. 7, the same, seen on its face. Fig. 8, the 
same, seen from below, showing the small transverse chink in its base, which answers to a 
corresponding line in the bottom of the cup, indicating the point of its attachment. Fig. 9, 
the small cup which bears the seed, from which it is quite free, except on the small line of 
the chink: all nat. size. Fig. 10, a longitudinal section of the seed, magnified, showing 
the rather soft chartaceous outer tunic (evidently an arillus), which is quite free from the 
second membranaceous integument, there being a considerable vacant space between them ; 
it is in the base of this outer tunic that we find the small basal chink above described. 
Fig. 11, the same, with the outer tunic removed, showing the second tunic, which is 
membranaceous and semitransparent ; all round its marginal edge is seen one continuous 
peripheral cord of spiral vessels, both extremities meeting at the base, and in its course 
passing over the apical chalaza : this tunic is evidently the testa, because it contains the 
raphe, and through it is perceived the inner mteg-ument (or tegmen), which is somewhat 
smaller and more contracted towards the base, where it terminates in a filamentous neck, 
which is united there to the mouth of the testa. Fig. 12, the embryo, extracted from a 
very thin albumen. Fig. 13, the same, seen edgeways. 
F. Details of Alphitobia excelsa. 
Fig. 1, a drupe. Fig. 2, its two endocarpal nuts extracted. Fig. 3, a nut seen edgeways. 
Fig. 4, the same, seen on its ventral face, showing its sutural line of dehiscence. Fig. 5, 
the endocarp bursting open, shoTvdng its enclosed seed. Fig. 6, the same, with the seed 
removed. Fig. 7, the seed extracted, seen on its ventral face. Fig. 8, the same, seen on 
its dorsal face : all nat. size. Fig. 9, the same, magnified, to show more distinctly the 
outer lax membranaceous tunic, with its edges imbricately folded over each other on the 
dorsal face, this fold being on the face eontrary to the line of dehiscence of the epicarp. 
Fig. 10, the same, unfolded, showing the enclosed seed. Fig. 11, the same, with the seed 
removed ; it is thicker at the base than at the more membranaceous margins : this appears
