Salvia Sclarea, L. (fig. 589). 



Fruit separating into four nutlets (or fewer by abortion), each 

 consisting of an outer soft integument and an inner thick and leathery 

 one, and containing one seed. 



Seed obovoid, pale brown, very finely reticu- 

 late ; testa thin, membranous ; hilum basal and 

 slightly oblique ; raphe ventral or on the same 

 side to which the hilum is directed, passing 

 along to a point above the middle of the seed ; 

 chalaza small, punctiform, above the middle of 

 the seed. 



Endosperm forming an extremely thin layer 

 surrounding the embryo, and adhering to the 

 testa. 



Embryo straight, large, colourless, filling 

 the interior of the seed and conforming to it ; 

 cotyledons plano-convex, following the outline 

 of the seed and accordingly broadly orbicular 

 or oval in longitudinal section, entire at the apex, 

 slightly notched at the base ; radicle very short, 

 stout, almost included between the cotyledons.
