Rubus neomexicanus is recognized by its erect, unarmed stems, relatively small, simple leaves with acute to obtuse lobes, the terminal prominent, deeply cordate base, moderately hairy abaxially, large flowers, white petals, and densely long-hairy, clavate styles. The species is similar to R. bartonianus and R. deliciosus, and treating it as a variety of the latter species would be reasonable, as W. O. Focke (1910) considered the two conspecific.
