Buxus cipolinica Lowry & G.E.Schatz, a distinctive new species from central Madagascar, is described and illustrated. It most closely resembles B. humbertii G.E.Schatz & Lowry, but differs in several characters, including the shape of its leaves and of the sepals in its female flowers. This Critically Endangered species is known only from a single highly threatened stand of remnant native vegetation on marble substrate situated south of the town of Ambatofinandrahana.
