Discussion

Hybrids between subsp. strigosus and Rubus occidentalis, including the cultivated purple raspberries, have usually gone under the name R. ×neglectus Peck. Peck did not treat R. neglectus as a hybrid, although his description, based on plants from northeastern New York, acknowledged the plants to be intermediate between the two taxa. L. H. Bailey (1941–1945) suspected R. neglectus to be a distinct species of local range. The fruit of these plants has a strikingly distinct taste; Peck noted that the locals referred to it as cream berries. M. L. Fernald (1900) misapplied the name R. idaeus var. anomalus Arrhenius to reduced, unarmed sterile plants of subsp. strigosus with simple leaves on the floricanes; such plants were later described by Blanchard as R. egglestonii. Rubus viburnifolius (Greene) Rydberg [not Franchet] is an illegitimate name that applies here.
