peculiar mode of placentation and the central columella, magnified. Fig. M, a fruit from 
which the fleshy pericarp has fallen away, nat. size. Fig. 9, the persistent calyx, with 
the four carpophora or rigid portions of the columella from which the four achenia have 
fallen away. Fig. 10, the four achenia higeminately attached in pairs, as seen from 
above, with the four central carpophora from which they are suspended. Fig. 11, one of 
the achenia, seen on its ventral face : all nat. size. Fig. 12, the same, with the deflected 
portion of its carpophorum, showing the lateral channel leading into the cell, magnified. 
Fig. 13, the same, viewed sidewise. Fig. 14, the same, seen on its dorsal face. Fig. 15, 
a transverse section of the same, showing the small osseous portion in the ventral angle, 
with the lateral channel leading into the cell ; the major portion, consisting of long, 
transverse, centripetal cells, is seen to form its dorsal substance. Fig. 16, the central 
columella, which withers into four rigid carpophora, from the summit of which one of the 
achenia is suspended. Fig. 17, a longitudinal section of the same across the ventral 
angle, showing the small nucumentaceous portion, with the aperture leading into the 
cell. Fig. 18, a seed, with its funicle and raphe : all equally magnified.

Fig. 19, the ripe drupaceous fruit. Fig. 20, the same, with half of its fleshy pericarp 
removed, showing two of the enclosed achenia. Figs. 21 & 22, an achenium, seen on its 
side and ventral face. Fig. 23, a transverse section of the same. Fig. 24, the persistent 
calyx and columella, where the carpophora are enveloped by fleshy matter : all nat. size, 
and taken from actual observation.
