semi-species

[Ron Kaneen]

Peter Price defines semispecies similarily:

"Semispecies are groups of populations, intermediate between good races and
good species, that are connected by reduced interbreeding and gene flow.
They can arise during gradual divergence of a parental stock into two good
species."
(Price, 1996)

He suggests that *Plantanus raemosa* and *P.wrightii* as an example.
