groupings or populations within a species that are distinguishable by morphological characteristics or, sometimes, by physiological or behavioural traits
A subclass of the genus that groups members by their geographical location or other descriptive variation Also known as a variety
A group somewhat lessdistinct than speciesusually are, but based on characters more important than those which characterize ordinary varieties; often, a geographical variety or race
