Plate 88. — Coscinium fenestratem. 
A portion of a male plant in flower, and of a female plant in fruit. 
Fig. 1, a head of sessile flowers on one of the branches of the inflorescence. Fig. 2, a 
single male flower : both nat. size. Fig. 3, a flower expanded, magnified. Fig. 4, the two 
basal bracts. Fig. 5, the outer series of three sepals. Fig. 6 , the three intermediate 
sepals. Fig. 7, the three inner sepals, in difllerent positions. Fig. 8, a transverse section 
of one of the sepals, to show its fleshy substance. Fig. 9, the six stamens, three of them 
being free, the others monadelphous : all magnified to the same scale. Fig. 10, the three 
monadelphous stamens, showing the points of attachment of the others to the base of the 
central column. Fig. 11, the three free stamens: all more magnified. Fig. 12, a fruit on 
its stipitate support, nat. size. Fig. 13, the same, with half the pericarp removed. 
Fig. 14, the putamen, seen sideways. Fig. 15, the same, viewed on the dorsal side. 
Fig. 16, a longitudinal section of the same, showing the thickness of its substance, the 
internal condyle to which the seed is attached, and one of the external channels leading 
into it. Fig. 17, a transverse section of the same, showing the two channels from the 
exterior into the interior of the condyle. Fig. 18, the seed separated from the putamen, 
showing the large vacuity on its ventral face, moulded round the condyle. Fig. 19, the 
same, viewed laterally, showing the complicated fissures of the ruminated albumen, into 
which the plicatures of the attenuated integument are insinuated. Fig. 20, a longitudinal 
section of the same, showing the two portions of the albumen, the inner thick and rumi- 
nated by innumerable fissures, the outer thin and homogeneous, the embryo being im- 
bedded and concealed between them. Fig. 21, a transverse section illustrating the same. 
Fig. 22, the embryo separated, showing the small superior radicle and the two divarica- 
ting laciniated cotyledons: all nat. size. Fig. 23 is a magnified view oifig. 21. Fig. 24 
is the embryo magnified. Fig. 25 is a transverse section of the stem of the plant, to show 
the peculiar arrangement of the medullary rays in the wood.
