Malva weinmanniana (Besser ex Rchb.) Conran, a new name for the pink-flowered form of M. preissiana Schltdl. (Malvaceae)

Abstract

The two morphotypes of the Australian endemic Malva preissiana Miq. (Austral Hollyhock) are here regarded as separate, distinct species with the white-flowered M. preissiana a coprophilic halophyte on seabird-dominated near-shore islands, or rarely mainland shores or inland salt lakes used by seabirds. Malva weinmanniana (Besser ex Rchb.) Conran, based on Lavatera weinmanniana Besser ex Rchb., is the new name applied to the more common, pink-flowered, largely mainland taxon. The names L. weinmanniana, L. plebeia var. eremaea J.M. Black., L. plebia var. tomentosa Hook fl, and M behriana Schltdl. are lectotypified and their statuses discussed. A key to the taxa and a table of comparisons is supplied.
