Shrubs, (10–) 20–30 (–35) dm, unarmed. Stems erect, sparsely to moderately short-hairy, sparsely stipitate-glandular, not pruinose. Leaves deciduous, simple; stipules lanceolate to narrowly ovate, (4–) 6–8 (–10) mm; blade cordate to broadly ovate, (2.5–) 3.5–5.5 (–6.5) × (2.5–) 3.5–5.5 (–8) cm, base shallowly to deeply cordate, palmately, shallowly to deeply 3–5 (–7) -lobed, margins coarsely doubly dentate, apex acute to broadly obtuse, abaxial surfaces moderately hairy, sparsely stipitate-glandular. Inflorescences 1 (–2) -flowered. Pedicels sparsely to moderately hairy, sparsely to densely short to long-stipitate-glandular. Flowers bisexual; petals white, broadly obovate to suborbiculate, (15–) 20–30 (–35) mm; filaments filiform; ovaries glabrous, styles clavate, villous. Fruits red, hemispheric, to 1 cm; drupelets 20, coherent, separating from torus. 2n = 14.

Discussion

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.
