ANATOMY OF ENHALUS ACOROIDES. 369 
Halfway between the bend and the fusion two large branches (d) on each side are 
emitted in the median plane and run outwards and upwards, branch repeatedly, and 
anastomose and form part of the ring of peripheral bundles of the ovary. 
Immediately after the median bundles fuse the fusion-bundle divides into from six to

eight branches (text-figs. 7 & 11, f), which bend obliquely out to the midribs of the 
carpels. Branches of these, as they bend, help to form the peripheral ring of bundles of 
the ovary. 
The vascular structures of the male and female inflorescences show a remarkable 
similarity in plan; the fate, the subsequent division, and the branching of the median 
bundles are identical, except that the end of the male peduncle seems to be pushed up 
to form a tongue, so that the horizontal branches bend down obliquely. 
Flower (text-figs. 12 & 13).—The perianth-leaves are in two dissimilar whorls of three 
petals (p) and three sepals (s). They both consist of an epidermis and parenchyma-cells 
from three to four layers thick. The petals have denser contents than the sepals and are 
very much crinkled, as they fold between the six to eight pairs of stigmas (text-fig. 12, s/). 
There are very few tannin-cells. 
The inferior ovary has six to eight forked placentze, which project nearly to the centre 
of the ovarial cavity (text-fig. 13, pl). In the centre is a small column (c) with a 
ular structure of

the carpels is similar to that of the leaf, as there is a large midrib pr e( 
in the middle of each carpel and a marginal bundle (m', m') on either side.
