first leaves of plants-- thought of as evol.vestiges or fetus-differences

IIRC monocots have 0-2 cotyledons and dicots 2-6.
The idea of dicots as a natural group is being abandoned.
It may be that the eudicots do have always two cotyledons, I would have to
check.

The eudicot _Cyclamen_ (Primulaceae) only has one cotyledon. [Ref: Grey-
Wilson's book on the genus.]
