blue : they contain several flattened reniform seeds, surrounded 

 by pulp,, and attached to the central placenta : their slender 

 terete embryo, enclosed in solid albumen, is spirally helical, that 

 is to say, it consists of more than a single volution, which is not 

 coiled in a plane, but rises in the middle in a slightly conical 

 form like the whorl of a snail-shell ; the radicle, equal in length 

 and diameter to the cotyledons, points to the basal angle of the 

 seed at some distance from the lateral hilum, which is situated 

 in a conspicuous sinus on the ventral margin. The following is 



that given in the ' Prodromus
