DESCRIPTION OF THE PLATES. 
edgeways : all nat. size. Fig. 22, the putamen, seen on its face, showing the three series 
of imbricating, laciniated, flat, pergameneous scales which surround the flat, concave, scuti- 
form condyle. Fig. 23, the same, shown endways : both magnified. Fig. 24, one of the 
scales, seen in front and edgeways, more magnified. Fig. 25, a cross section of the 
putamen, showing the seed and the hollow between the two plates of the condyle along 
the sutural line of division. Fig. 26, inner view of half the putamen, showing the hippo- 
crepiform cell of the seed and the groove from the basal hilum to the point of the attach- 
ment of the seed, at its sinus between the plates of the condyle. Fig. 27, the seed ex- 
tracted. Fig. 28, a cross section of the same, shovring the embryo imbedded in albumen : 
all equally magnified. 
Plate 130. — Sakcopetalttm Harveyancjm. 
A portion of a branch of the male plant in flower, and another of the female plant 
in fruit. 
Fig. 2, a peduncular branchlet of the inflorescence, supporting two flowers, nat. size. 
Fig. 3, the same, magnified. Fig. 4, the peduncle, with the two short pedicels from 
which the flowers have been removed. Fig. 5, one of the flowers, seen from above : 
all equally magnified. Fig. 6, four sepals. Fig. 7, four petals, both variable in number 
and alike in the two sexes : more magnified. Fig. 8, the six sterile stamens of the 
female flower. Fig. 9, the ovaries, three to six in number : all equally magnified. 
Fig. 10, a sterile stamen. Fig. 11, an ovary, seen sideways and in front, to show the 
form of the stigma: both more magnified. Fig. 12, four drupes on one receptacle. 
Fig. 13, one of the same upon the receptacle. Fig. 14, its putamen. Fig. 15, the same, 
seen edgeways : all nat. size. Fig. 16, a drupe, magnified. Fig. 17, its putamen, show- 
ing the hippocrepiform, tuberculous, broad margin surrounding the lunated, exeentric, 
scutiform condyle, with a small aperture near the margin. Fig. 18, a cross section of 
the same, showing the cell of the seed and the division made by the sutural line, 
which separates the condyle into two plates. Fig. 19, inside view of half the putamen so 
separated, showing the lunated cell of the seed surrounding the condylar plate perforated 
near the margin. Fig. 20, the seed covered by its membranaceous integument, which is 
expanded in its sinus, where it is insinuated between the plates of the condyle. Fig. 21, 
the same, deprived of its integument : all magnified on the same scale. 
Plate 131. — Htperb^na Domingexsis. 
A portion of a branch of the male plant in flower, and another of the female plant 
in flower and in fruit. 
Fig. 1, a branchlet of the raceme, nat. size. Fig. 2, the same, somewhat magnihed. 
Fig. 3, a bracteole. Fig. 4, the three outer sepals. Fig. 5, the three inner sepals. 
Fig. 6, the six petals. Fig. 7, the six stamens : all equally magnified. Fig. 8, a stamen 
before and after dehiscence, more magnified. Fig. 9, the three outer sepals of the female 
flower. Fig. 10, the three inner sepals. Fig. 11, the six petals. Fig. 12, the six 
sterile stamens. Fig. 13, the three ovaries. Fig. 14, one of the same on the receptacle 
(the others removed) : all magnified to the same scale. Fig. 15, a drupe on its pedicel, 
nat. size. Fig. 16, its smooth coriaceous putamen, with a short groove on each face. 
Fig. 17, a longitudinal section of the same, showing its bimarsupial cell, formed by an 
incomplete condylar septum, corresponding with the external grooves. Fig. 18, a cross
