DESCRIPTION OF THE PLATES. 
extracted, showing its pubescent testa. Fig. 15, a side view of the same. Fig. 16, a 
longitudinal section of the same. Fig. 17, the albumen, covered by the tegmen, with its 
basal chalaza, the testa having been removed. Fig. 18, a longitudinal section of the albu- 
men, showing the enclosed embryo. Fig. 19, the same, cut'crossways. Fig. 20, the embryo 
extracted, seen in front and edgeways : all nat. size. Fig. 21, the deciduous stipules, with 
their accompanying persistent glands. 
Plate 33. — A. Details of Khamntjs cathaeticus. 
Fig. 1, a drupe. Fig. 2, one of its three endocarpal nuts, seen edgeways. Fig. 3, the 
same, seen on the ventral face, showing its sutural line of dehiscence : all nat. size. Fig. 4, 
the same, in the act of its dehiscence, showing the enclosed erect seed, magnified. Fig. 5, 
the seed extracted, seen on its dorsal face, showing the longitudinal plicated channel. 
Fig. 6, the same, seen on the smooth ventral face of its external coriaceous tunic. Fig. 7, 
the same, seen on its dorsal face, with the external crustaceous tunic (arillus) removed. 
Fig. 8, the same, seen on the ventral face, after the removal of the external crustaceous 
tunic, showing the ventral line of raphe imbedded in this second membranaceous integu- 
ment (testa), with the chalaza in the apical sinus. Fig. 9, the same, seen on the dorsal face 
(fig. 7), but opened out in order to show the more conspicuous dorsal Hne of raphe (before 
hidden in the groove) which proceeds from the chalaza in continuity with the line of raphe 
of the opposite face. Fig. 10 is a view of fig. 8, opened out in like manner, the ventral 
line of the raphe, with a portion of the second integument in which it is imbedded, having 
been torn away, leaving the chalaza, which is agglutinated to the second and third integu- 
ments, and showing the gi’oove left in it by the removal of the line of raphe. Fig. 11, the 
continuous line of the ventral and dorsal raphe (as shown torn away in the preceding 
figure from the second integument, or membranaceous testa). Fig. 12, the embryo re- 
moved from the albumen, in its natural plicated form. Fig. 13, the same opened out. 
Fig. 14, the same, seen edgeways. Fig. 15, a transverse section of the seed, showing the 
external crustaceous arillus with its infolded plates, the two integuments (testa and teg- 
men) showing the separation that exists between them in the axis of the seed in the form 
of a square hoUow space ; the dorsal raphe is there seen imbedded in the testa, within the 
groove formed by the pHcatiu'e of the seed, and the ventral raphe is shown on the contrary 
side concealed by the arillus. Fig. 16, a transverse section of the arillus removed, repre- 
sented in its natural form of plicature. Fig. 17, a transverse section of the two proper 
integuments (testa and tegmen), in their natural form, with the vacant space existing 
between them in the axis, showing the relative position of the dorsal and ventral line of 
raphe. Fig. 18, a transverse section of the albumen and enclosed embryo, in their naturally 
plicated form. Fig. 19, a transverse section of the embryo extracted : all equally mag- 
nified. Fig. 20, longitudinal section of one of the cells of the ovary, with an erect 
anatropous ovule, supported on its long fimicle, which is continuous with its dorsal raphe. 
Fig. 21, the same o^e removed, before its impregnation. Fig. 22, the same ovule after 
impregnation, with the arilliform outer coating grown over it, and enclosing the funicle : all 
much magnified. 
B. Details of Ehamnus chloeophoeus. 
Fig. 1, a drupe. Fig. 2, one of its endocarpal nuts, seen on its ventral face, showing 
the line of its dehiscence. Fig. 3, the same, seen sideways. Fig. 4, the enclosed seed : all 
nat. size. Fig. 5, a transverse section of one of the nuts, in the act of its dehiscence, with 
the enclosed seed, showing the position of its lateral chink and hilar scar in relation to the
