tailieunhanh - The taxonomic revision of Alcea and Althaea (Malvaceae) in Turkey

Alcea L. is represented by 18 species and Althaea L. by 4 species in the Flora of Turkey. Seventeen species of Alcea and all species of Althaea were collected. One new cultivated record of Alcea was added. Contrary to the Flora of Turkey, the endemicity of Alcea apterocarpa (Fenzl) Boiss., Alcea calvertii (Boiss.) Boiss., and Alcea fasciculiflora Zohary has not been proved. | Research Article Turk J Bot 36 (2012) 603-636 © TÜBİTAK doi: The taxonomic revision of Alcea and Althaea (Malvaceae) in Turkey Mehmet Erkan UZUNHİSARCIKLI*, Mecit VURAL Department of Biology, Faculty of Science, Gazi University, 06500, Teknikokullar, Ankara - TURKEY Received: ● Accepted: Abstract: Alcea L. is represented by 18 species and Althaea L. by 4 species in the Flora of Turkey. Seventeen species of Alcea and all species of Althaea were collected. One new cultivated record of Alcea was added. Contrary to the Flora of Turkey, the endemicity of Alcea apterocarpa (Fenzl) Boiss., Alcea calvertii (Boiss.) Boiss., and Alcea fasciculiflora Zohary has not been proved. The threat category of Alcea fasciculiflora and Alcea pisidica . has been changed to CR, while they were placed in DD according to the Red Data Book of Turkish Plants. As a result of this study, determination keys, detailed descriptions, and illustrations of Alcea and Althaea species are presented. Phytogeographical regions of all taxa are suggested. Key words: Revision, Alcea, Althaea, Malvaceae, Turkey Introduction Alcea L. and Althaea L. are taxonomically assigned to Malvaceae subfam. Malvoideae, tribe Malveae. As a result of the limited time and resources during the preparation of the Flora of Turkey, many taxonomical problems in some genera and sections were only mentioned but not solved. The editors suggested that further revisions should be carried out to solve these problems (Davis & Hedge, 1975). Alcea and Althaea are examples of those with many unresolved taxonomical problems. Several recent revisions on different groups of flowering plants have presented significant taxonomic solutions within problematic groups (Parmaksız & Özcan, 2011; Tekşen & Aytaç, 2011). In terms of taxonomic history, first Tournefort and then Linnaeus in Species Plantarum (1753) indicated that Alcea and Althaea are 2 separate genera attributed to Malvaceae. In the
