DESCRIPTION’ OF THE PLATES. 
sepals, seen in three different positions, showing them to be smooth inside. Fig. 12, one 
of the petals similarly placed. Fig. 13, the single ovule: all equally more magnified. 
Fig. 14, the ovary, showing the form of the style and stigma, still more magnified. Fig. 
15, the same, shown edgeways. Fig. 16, a longitudinal section of the same, to show the 
attachment of its ovule : hoth equally magnified. 
Plate 115. — Cissajipelos iiicbocakpa. 
A portion of a male plant in flower, and another of the female plant in flower and in 
fruit. 
Fig. 1, a male flower in bud. Fig. 2, the same, after expansion : hoih nat. size. Fig. 3, 
the flower expanded, seen from above. Fig. 4, the four sepals. Fig. 5, the cup-shaped 
petal. Fig. 6, the monadelphous stamen : all equally magnified. Fig. 7, the petal. 
Fig. 8, the stamens with six anther cells on the edge of a peltated connective supported 
on a central column. Fig. 9, the same, showing the transverse dehiscence of the cells : 
all more magnified. Fig. 10, a bract concealing three female pedicellated flowers, mag- 
nified four times. Fig. 11, one of the three pedicellated flowers. Fig. 12, its single sepal. 
Fig. 13, its single petal, fixed inside upon its claw. Fig. 14, the single ovary : all 
equally magnified. Fig. 15, a drupe. Fig. 16, its putamen: hoth vat. size. Fig. 17, 
the putamen, showing on its face three radiating and concentric rows of irregular tuber- 
cles, surrounding the central, concave, discoidal, imperforated condyle. Fig. 18, the 
same, seen on its edge, showing the peripherical line of suture. Fig. 19, half of the puta- 
men, divided along the sutural line, showing internally the hippocrepiform cell from which 
the seed is extracted, with the groove within the centre of the condylar space for the con- 
veyance of the nutritive vessels from the base to the bottom of the sinus at the point of 
the attachment of the seed as there shown. Fig. 20, the hippocrepiform seed extracted, 
crenately moulded to the shape of the cell and covered by its thin integument, in the 
sinus of which is shown the point of attachment of the seed to the condyle, and in com- 
munication, by means of the nourishing vessels, with the hilum at the basal margin on the 
outer extremity of the groove. Fig. 21, a transverse section of the same, showing the 
embryo imbedded in the albumen, and the cicatrix in the sinus which marks the point of 
attachment of the seed to the condyle. Fig. 22, a longitudinal section of the same, 
showing the form and relative size of the embryo imbedded in simple albumen. Fig. 23, 
the embryo extracted, viewed endways. Fig. 24, the hippocrepiform terete embryo, with 
incumbent cotyledons : all magnified on the same scale. 
Plate 116. — Axtizoma Harvetana. 
A portion of a male plant in flower, another of the male plant of Antizoma Burchelliana 
in flower, and another of the female plant of Antizoma angustifolia in flower. 
Fig. 1, a single axil of A. Harveyana, showing its peculiar infrapetiolar spine, magni- 
fied. Fig. 2, a single pedicellated flower, out of the small axillary capitated inflorescence 
of the same, with its basal bract, much magnified. Fig. 3, the same, viewed from above. 
Fig. 4, one of the four unguiculatcd sepals, seen from below and above. Fig. 5, the single 
cup-shaped petal. Fig. 6, the same, including the stamen. Fig. 7, the same, with half
