Continuing a series of miscellaneous contributions on the taxonomy, nomenclature, site-ecology and chorology of vascular plants of Turkey, the second instalment deals with 15 taxa of the families Alliaceae, Apiaceae, Asteraceae, Brassicaceae, Colchicaceae, Dipsacaceae, Euphorbiaceae, Lamiaceae, Papaveraceae and Ranunculaceae. Allium antalyense, Cephalaria gazipashensis subsp. pilifera and Teucrium pseudaroanium are described as new to science and illustrated. Allium (sect. Allium) antalyense belongs to the informal Sphaerocephalon group and is closely allied to A. reuterianum. It is an overlooked local endemic of the Western Taurus (Teke Dağı) and grows in the subalpine belt on limestone. Teucrium (sect. Teucrium) pseudaroanium was found in the Demre Çayı valley in the province of Antalya, where it inhabits limestone marble cliffs of the thermo-Mediterranean belt. It forms together with the Greek endemic T. aroanium and the SW Anatolian endemic T. alyssifolium a group of closely related species that are linked by reticulately distributed characters. Characters and ecological requirements of the members of this T. aroanium group are discussed; the taxonomically important trichome types are particularly considered and figured by SEM micrographs. Chamaesyce nutans, R. peltatus s.str. and Zuvanda exacoides are new records for the flora of Turkey. Three taxa are suggested to be sunk in synonymy, viz. Allium vuralii (in A. scabriflorum), Draba terekemensis (in D. imeretica) and Ranunculus kastamonuensis (in R. peltatus). The new combinations Chamaesyce forskalii and Colchicum figlalii are validated. New keys are provided for the genus Chamaesyce and the infraspecific taxa of Camelina hispida.
