''Rosmarinus'' 〔''Sunset Western Garden Book,'' 1995:606–607〕 is a small genus of woody, perennial herbs with fragrant evergreen needle-like leaves in the family Lamiaceae, native to the Mediterranean Basin. ==Description== ''Rosmarinus officinalis'' (rosemary), widespread in the Mediterranean region, and ''Rosmarinus eriocalyx'', native to northwest Africa and southern Spain have long been widely recognized. ''Rosmarinus tomentosus'' was first recognized as a separate species in 1941. ''Rosmarinus palaui'' was first described as a species in 2002, although recognition of this species remains controversial. Recent research has indicated that while ''R. tomentosus'' froms a monophyletic group, this group is nested within a paraphyletic ''R. eriocalyx''. ''Rosmarinus eriocalyx'' differs from the well-known herb rosemary in its smaller leaves, only 5–15 mm long and less than 2 mm broad, and densely hairy flower stems. It also tends to be lower-growing, often under 25 cm tall and prostrate, and never exceeding 1 m tall (''R. officinalis'' can reach 1.5 m, exceptionally 2 m, tall). ;Species and nothospecies accepted by the Kew World Checklist〔(Kew World Checklist of Selected Plant Families )〕 # ''Rosmarinus eriocalyx'' Jord. & Fourr. - Spain, Morocco, Algeria, Libya # ''Rosmarinus × lavandulaceus'' de Noé - Spain, Morocco, Algeria ''(R. eriocalyx × R. officinalis)'' # ''Rosmarinus × mendizabalii'' Sagredo ex Rosua - Granada region of Spain ''(R. officinalis × R. tomentosus)'' # ''Rosmarinus officinalis'' L. – Rosemary - Portugal, Spain, France, Italy, Greece, Albania, Yugoslavia, Morocco, Algeria, Libya, Tunisia, Egypt, Cyprus, Turkey; naturalized in Bulgaria, Crimea, Azores, Canary Islands, Cape Verde, Bermuda, Texas, central Mexico # ''Rosmarinus palaui'' (O.Bolòs & Molin.)
