the exterior stamen two small 
collateral and fleshy bodies, which 
are designated a paléole. 
When the ovule has been sub- 
jected to the fertilising influence 
of the pollen-tubes, it is trans- 
formed into a seed, which presents 
this peculiarity, that it is blended 
firmly with the fruit by its in- 
tegument in such a manner as 
to constitute what botanists call 
cariopsis—a term used when the 
pericarp of an indehiscent seed- 
vessel is membranous, and ad- | 
heres firmly to the integument, as | 
in Fig. 351, which represents 
a cariopsis of Buck- 
greater part of this is | 
composed of a farina- 
Ceous albumen. On the outside 
and beneath, a small distinct 
body is perceptible, sunk in the 
Surface, and scarcely projecting 
fromit. Thisis the embryo which, 
““pported upon the albumen by 
_1t, forms a cushion-like enlarge-
