A new alien record for the flora of Turkey: Sigesbeckia pubescens (Compositae)

An Asian species, Sigesbeckia pubescens (Makino) Makino (Compositae), is recorded as an alien for the flora of Turkey. The specimens were collected from A8 Artvin and a distribution map for the species is provided. | Turkish Journal of Botany Turk J Bot (2013) 37: 188-190 © TÜBİTAK doi:10.3906/bot-1202-45 http://journals.tubitak.gov.tr/botany/ Research Note A new alien record for the flora of Turkey: Sigesbeckia pubescens (Compositae) 1, 2 Fergan KARAER *, Salih TERZİOĞLU Department of Science, Faculty of Education, Ondokuz Mayıs University, 55200, Samsun, Turkey 2 Department of Forest Botany, Faculty of Forestry, Karadeniz Technical University, 61080, Trabzon, Turkey 1 Received: 29.02.2012 Accepted: 23.07.2012 Published Online: 26.12.2012 Printed: 22.01.2013 Abstract: An Asian species, Sigesbeckia pubescens (Makino) Makino (Compositae), is recorded as an alien for the flora of Turkey. The specimens were collected from A8 Artvin and a distribution map for the species is provided. Key words: Compositae, new record, Sigesbeckia, Turkey Sigesbeckia pubescens (Makino) Makino, J. Jap. Bot. 1(7): 24 (1917). Basionym: Sigesbeckia orientalis L. f. pubescens Makino, Bot. Mag. (Tokyo) 18: 100 (1904). ≡ Sigesbeckia orientalis L. subsp. pubescens (Makino) H.Koyama, Fl. Jap. (Iwatsuki et al., eds.) 3b: 32 (1995). This species was collected during an expedition in A8 Artvin Province as part of an ongoing project entitled Longterm Development Plan of Hatila Vadisi National Park. We came across Sigesbeckia L. individuals with regularly toothed leaves (Figure 1). The genus found occurring as an alien taxon in Anatolia has been identified as S. orientalis L., which is widely distributed in the warmer countries of the world. At first glance it is quite normal to suppose that it is S. orientalis. We were not able to identify these specimens using the Flora of Turkey (Kupicha, 1975). These specimens seemed to be similar to S. pubescens according to the Flora of China (Shu, 2011). We considered that these specimens belong to S. pubescens (Makino) Makino (Figure 1), which is a new alien record for the flora of Turkey. Some taxa have already been newly recorded in areas close to this .
