Three New Species With Two Flowered Spikelets In Acantholimon (Plumbaginaceae) From East Anatolia, Turkey

Abstract

Three new species, Acantholimon bashkaleicum sp. nov., Acantholimon artosense sp. nov. and Acantholimon hoshapicum sp. nov. (Plumbaginaceae) are described and illustrated. The species are all confined to B9/B10 Van Province in East Anatolia where they grow either on calcareous mountain slopes or on mountain steppes. Diagnostic morphological characteristics from the closely related species are given, along with a discussion dealing with their taxonomic relationships, and their conservation statuses are pointed out. A revised key to the Acantholimon species with heterophyllous leaves, two or more flowered and four or more bracteated spikelets is also provided. (C) 2004 The Linnean Society of London.
