Rhodora 58:310. 1956, nom. inval.
Comment:
not validly published (Melbourne ICN Art. 38.13), as Shinners cited M. denticulata var. vulgaris Benth., nom. inval. (Melbourne ICN Art. 26.2) as the basionym for his name and neither Bentham nor Shinners provided a Latin description or diagnosis for the variety; Shinners should have transferred the autonym, M. denticulata var. denticulata (Melbourne ICN Art. 11.6)
