DESCRIPTION OF THE PLATES. 
Plate 121, — Cyclea Burstanni. 
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 lateral branchlet of the male inflorescence, showing the arrangement of the 
flowers, magnified. Fig. 2, a single pedicellated flower, nat. size. Fig. 3, the same, 
tnagnijled, showing its tubular calyx. Fig. 4, the calyx cut in two, to show the position 
of the coroUa and stamen. Fig. 5, the cup-shaped corolla, showing the four inflected 
segments of its border. Fig. 6 , the same, cut in half, to show more distinctly the inflec- 
tion of the segments. Fig. 7, the monadelphous stamen, with four anther-cells on a pel- 
tate connective: all magnified to the same scale. Fig. 8, a pedicellated female flower, 
nat. size. Fig. 9, the same, magnified. Fig. 10, the single sepal, pilose outside. Fig. 11, 
the single petal, flxed to the claw of the sepal. Fig. 12, the ovary : all equally magnified. 
Fig. 13, a drupe. Fig. 14, its putamen : both nat. size. Fig. 15, the drupe, magnified. 
Fig. 16, the putamen, with two rows of small tubercles on each face, surrounding the 
convex condyle. Fig. 17, the same, seen on its edge, to show its globosely ovate shape. 
Fig. 18, a longitudinal section of the same, along the peripherical line of suture, showing 
internally the hippocrepiform cell, and the groove leading from the hilar base into the 
two chambers of the large hollow condyle. Fig. 19, a cross section, showing the seed in 
its cell and the two hollow chambers of the condyle. Fig. 20, the hippocrepiform seed 
extracted, covered by its membranaceous integument, showing in its sinus the cord of 
vessels and the extended membrane by which it is attached to the condyle. Fig. 21, a 
section of the same deprived of its integument, showing the embryo enclosed in simple 
albumen. Fig. 22, the hippocrepiform terete embryo, with incumbent cotyledons ; all 
magnified to the same scale. 
Plate 122. — Peraphora robxjsta. 
The upper figure shows a portion of a branch of the male plant in flower, and the lower 
one of the female plant in flower, with an analysis of its fruit. 
Fig. 1, a portion of the male inflorescence, magnified. Fig. 2, a male flower on its 
pedicel, nat. size. Fig. 3, the same, magnified. Fig. 4, the globular calyx cut in half, to 
show the enclosed stamen. Fig. 5, the stamen. Fig. 6, the same, seen from above : all 
equally magnified. Fig. 7, a portion of the female inflorescence, magnified. Fig. 8, a 
pedicellated female flower, nat. size. Fig. 9, the same, magnified. Fig. 10, the two oppo- 
site sepals. Fig. 11, the ovary : all equally magnified. Fig. 12, the stigma, more magni- 
fied. Fig. 13, a drupe. Fig. 14, its putamen : both nat. size. Fig. 15, the putamen, 
showing three concentric series of spines, round an imperforated concave condyle, striated 
down the middle. Fig. 16, the same, seen edgeways : both magnified.
