pair, and form an

mediately or by the Intermediation of a placenta, which 
is a more or less evident development of the leaf-margins 
for the support of the ovules. Barely ovules are devel- 
oped from the whole internal surface of the ovary, or from 
various parts of it, in no definite order, directly from the 
walls, and without the Intervention of anything which can 
be regarded as a placenta. In gymnosperms the ovules 
are borne on the face of the carpellary scale or at its base 
or on metamorphosed leaf- margins, as in Cycat; or when 
there is no representative of the carpel, on the c'auline 
axis, seemingly as a direct growth of it. (Gray.) The 
only essential part of the ovule is its nueteut, or nweUw, 
as it has been termed recently, which Is usually invested 
by one or two coata, the primine and xcunJinr. The 
ats are sacs with a narrow orifice called the foramen, 
the closed vestige of which becomes the micropule. in the 
seed. The proper base of the ovule Is the chaltua, and It 
may be either sessile or on a stalk (funiculus) of its own 
The hilum is the scar left when the seed is detached 
from its funiculus. As to shape, ovules may be orthotro- 
pous, campylotropous, amphitropoua, or anatropous and 
as to i>..siti,,Ti in the ovary, they may be erect, ascending, 
Horizontal, pendulous, or suspended. In regard to num- 
bers, they may be solitary, few, or indefinitely numerous.
