The two varieties of M. quadrivalvis are very similar and are separated on technical differences of their leaflets.
Var. angustata - Leaflets with only the median vein evident on the lower surface
Var. floridana - Leaflets with evident lateral venation on lower surface

Variety angustata is a plant of sandhills, flatwoods and mesic hammocks. It is widespread in Florida.

Variety floridana is a plant of scrub and dry sandhills.
