[ad. Sp. alcaneta (also arcaneta), dim. of alcana, alcaña: see ALCANNA. The diminutive form was applied to a European plant yielding red dye, the Anchusa or Alkanna tinctoria, (formerly sometimes called Alkanna spuria) to distinguish it from the oriental Al-kanna = henna. Hence it has been extended to other species of Anchusa and allied genera. A variant is ORCANET, a. Fr. orcanète, ad. Sp. arcaneta above.]
