DESCKIPTIOX OF THE PLATES. 
central groove which conveys the nourishing vessels from the base to the point of attach- 
ment of the seed to the condyle. Fig. 25, the seed extracted, showing the extension of 
the integument at the sinus where it penetrates between the two plates of the condyle 
Avith its attached cord of vessels : all equally magnified. 
Plate 119. — Stephaxia glabra. 
A portion of a branch of the male plant in flower, and another of the female plant in 
flower, with an analysis of its fruit. 
Fig. 1, one of the male umbeUules, bracteated at base, nat. size. Fig. 2, one of the 
pedieeUated flowers, nat. size. Fig. 3, the same, magnified. Fig. 4, the same, with the 
sepals thrown back horizontally, showing the petals and stamen. Fig. 5, the three outer 
sepals. Fig. 6, the three inner sepals. Fig. 7, the three petals, marked by two collateral 
glands. Fig. 8, the stamen, with a six-celled anther. Fig. 9, a section of the same, to 
show the attachment of the cells round a peltate connective : all magnified to the same 
scale. Fig. 10, one of the seven umbeUules of the female inflorescence, forming a racemule 
of five petiolated flowers, nat. size. Fig. 11, the same, magnified. Fig. 12, a flower, 
magnified. Fig. 13, one of the three sepals (one or two sometimes abortive). Fig. 14, 
the three petals. Fig. 15, the ovary, with its laciniated stigma ; all equally magnified. 
Fig. 16, a drupe. Fig. 17, its putamen : both nat. size. Fig. 18, the putamen, having 
two rows of tubercles on the margin of each face, around the flat concave condyle, always 
perforated in the centre. Fig. 19, the same, viewed on its edge, showing the peripherical 
line of suture. Fig. 20, a cross section of the same, showing the perforated, concave, dis- 
coid condyle, and the ceU enclosing the hippocrepiform seed. Fig. 21, inside view of half 
the putamen, divided by the sutural Une, showing the hippocrepiform ceU, the perforated 
condyle, and the groove leading from the basal hilum. Fig. 22, the seed extracted, with 
its integument expanded in the sinus, where it penetrates between the two plates of the 
condyle. Fig. 23, a longitudinal section of the same deprived of its integument, showing 
the embryo imbedded in simple albumen. Fig. 24, the hippocrepiform terete embryo, 
with incumbent cotyledons : all magnified to the same scale. 
Plate 120. — Clambes araneoses. 
A portion of a branch of the male plant in flower. 
Fig. 1, an ultimate branchlet of the inflorescence, nat. size. Fig. 2, the same, magnified 
to show the imbricated bracteoles from which most of the flowers have faUen. Fig. 3, a 
flower before and after expansion, equally magnified. Fig. 4, a flower before expansion, 
on its pedicel, much more magnified. Fig. 5, the same expanded, showing the smaU erect 
petals round the foot of the staminal column. Fig. 6, the same, with the petals thrown 
back to show they are opposite to the sepals (not dtemate with them as in Eufihorbiacect : 
see remarks in the Ust of addenda, p. 393). Fig. 7, the three outer sepals. Fig. 8, the 
three inner sepals. Fig. 9, the stamen surrounded by the smaU petals. Fig. 10, the six 
petals: all magnijied to the same scale. Fig. 11, the stamen, showing the transverse 
dehiscence of the anther-ceUs. Fig. 12, the six anther-cells fixed on the margin of a 
peltate connective (as in Cissampelos), seen from above : both more magnified.
