''Achlys'' is a small genus of flowering plants in the barberry family (Berberidaceae), which it shares with genera such as ''Berberis'' and ''Vancouveria''.〔Gilkey, Helen M. & Dennis, La Rea J. (2001). ''Handbook of Northwestern Plants''. Oregon State University Press. ISBN 0-87071-490-2 p. 161〕 == Species == There are either two or three species, depending on the authority. ''Achlys triphylla'' and ''Achlys californica'' are both native to western North America. Another ''Achlys'' is found in Japan: some authorities treat this as a subspecies of ''A. triphylla'', while others, especially in older treatments, call this ''Achlys japonica''. Still others consider ''A. triphylla'' and ''A. californica'' too similar to be separate species. The common names for these plants include vanilla leaf (sometimes written as vanilla-leaf or vanillaleaf, depending on the taxonomist or flora), deer's foot and sweet after death, referring to the vanilla scent of its crushed leaves.〔〔Pojar & MacKinnon (2004). ''Plants of the Pacific Northwest Coast'' (Revised Edition). Lone Pine Publishing. ISBN 1-55105-530-9 p. 312〕 The Plant List recognizes two species, with ''A. californica'' regarded as a subspecies of ''A. triphylla'' *''Achlys triphylla'' (Sm.)
