Synopsis of Turkish Acantholimon Boiss. (Plumbaginaceae)

A synopsis of Acantholimon in Turkey is given on the basis of a revisional study conducted in Turkey by the authors. An account of 52 species, ten subspecies, and 17 varieties is given, including keys to the species, subspecies, and varieties, and a general indication of their distribution, as well as their conservation status in Turkey. Seven new taxa, namely A .  ekimii sp. nov. , A. capitatum ssp. sivasicum ssp. nov. , A. calvertii var. glabrum var. nov. , A. huetii var. breviscapum var. nov. , A. acerosum ssp. longibracteolorum ssp. nov. , A. lycaonicum ssp. cappadocicum ssp. nov. , and A. halophilum var. coloratum var. nov. , are described, together with a few new combinations. A. wiedemannii , A. iconicum , and A. lycaonicum , described from Turkey in the past, but placed under other species as synonyms in the Flora of Turkey , are recognized once again as good species. A. multiflorum and A. parviflorum are given a species status. In Turkey, the presence of A. latifolium , A. araxanum , A. lepturoides , A. hohenackerii , A. senganense , A. fominii , A. petraeum , and A. tragacanthinum is also confirmed.  © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society , 2007, 154 , 397–419.     

A new species of Viola (Violaceae) from Turkey

A new species of Viola , V. kizildaghensis M. Dinç & S¸. Ẏlḋṙml̇, from Turkey is described and illustrated. It is found on the rocky slopes of K̇żldǎ, K̇żldǎ National Park, in the vilayet of Isparta, south-west Turkey, at an elevation of 1350–1600 m. It belongs to Viola , subsection Viola , and is similar to the Lebanese endemic V. libanotica Boiss., distinguished by its lanceolate, cuneate based leaves, pinkish-purple flowers with white throats, glabrous lateral petals, and peduncles bearing the mature fruit procumbent and pubescent. It is somewhat similar to another species from south-west Turkey, V. sandrasea Melchior, that is endemic to Sandras Dǎ in the vilayet Mǔla; it is distinguished from this by the characters listed above, its pubescent leaves and peduncles, and its linear-lanceolate to lanceolate stipules which have short, gland-tipped fimbriae. © 2002 The Linnean Society of London, Botanical Journal of the Linnean Society , 2002, 138 , 483–487.     

A new species of Viola (Violaceae) from south-west Turkey

Viola dirimliensis Blaxland is described as a new annual species from south-west Turkey, belonging to section Melanium Gingins. It was found growing only on serpentinite, in two adjacent locations in Mula vilayet, west of Antalya, at altitudes of 1500–1690 m. The locations were typical serpentinite barrens, almost bare of vegetation, with some plants of Muscari macrocarpum , and a few trees of Pinus nigra var. caramanica . The Viola is named after the type location, the Dermil Pass or Dirimli Geçidi, where the tiny plants were growing between the rocks on south-facing slopes. Their distinct golden-yellow flowers are unlike any of the other small annual Viola species found in Turkey.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 145 , 505–509.     

A new Pseudophoxinus (Teleostei,Cyprinidae) species from Asi River Drainage (Turkey)

Pseudophoxinus turani sp. n. is described from the İncesu Spring (Hassa-Hatay) drainage of Asi River, Turkey. It is distinguished from other Eastern Mediterranean Region Pseudophoxinus species by a combination of characters: lateral line incomplete, with 12–25 (commonly 16–21) perforated scales and 38–46+2-3 scales in lateral series (commonly 41–44+2-3); 10–11 scale rows between the lateral line and dorsal-fin origin; 3–4 scale rows between the lateral line and the pelvic–fin origin; dorsal fin with 7½ branched rays; anal fin commonly with 7½ branched rays; 8-11gill rakers on the first branchial arch; dorsal profile markedly convex with marked hump at the nape, ventral profile less convex than dorsal profile; a small, irregular, black blotch on the base of the caudal fin; mouth terminal, with slightly distinct chin, its corner not reaching vertical through anterior margin of eye; snout somewhat long, with rounded tip; and its length greater than eye diameter.     

A new species of Linum (Linaceae) from west Anatolia, Turkey

A new species, Linum vuralianum Yılmaz & Kaynak, is described and illustrated from west Anatolia, Turkey. It is closest to L. flavum L., but differs by its annual or biennial life form, the presence of rosette leaves at anthesis, and the absence of staminodes. The World Conservation Union (IUCN) threat category and observations on the population are noted. The geographical distribution of the new species and its related taxon is given.  © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 459–462.     

A new species of Dianthus (Caryophyllaceae) from Mount Erciyes,central Anatolia,Turkey

Dianthus aytachii C.Vural from Mount Erciyes, central Anatolia (Turkey) is described and illustrated. It is considered to be endemic to Mount Erciyes. The morphological differences from the closely related species Dianthus zederbaueri Vierh. are discussed. The World Conservation Union (IUCN) threat category and observations on the ecology of the populations are noted. The pollen and seed morphology of D. aytachii and D. zederbaueri were examined by light microscopy and scanning electron microscopy. The geographical distribution of the new species is mapped. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 55–61.     

A new species of Arabis (Brassicaceae) from inner Anatolia

A new species of Arabis L., A. erikii Mutlu sp. nov. , is described and illustrated. The species is restricted to inner Anatolia, south-west of Sivas. It grows on steppes. Diagnostic morphological characters are given for discrimination from the most similar taxa.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 145 , 251–256.     

A new species of Centaurea (sect. Phalolepis, Compositae: Cardueae) from eastern Peloponnisos, Greece

A new species of Centaurea L. , Centaurea leonidia Kalpoutz. & Constantin. , from two localities west and south-west of the town of Leonidio in eastern Peloponnisos, Greece, is described and illustrated. It belongs to C . sect. Phalolepis , and taxonomically its closest relatives are C. heldreichii Halácsy , a very localized species from south-west Sterea Ellas (Greece) and, surprisingly, C. niederi Heldr., which belongs to sect. Acrolophus. The new species is currently known from two populations of less than 100 individuals each, growing on almost inaccessible cliffs close to the convent of Agios Nikolaos Sintzas (St. Nicolas of Sintza) and the slopes of Poundes summit. Several other Greek endemic species are found in the same areas. Centaurea leonidia is scientifically important as it belongs to a small group of taxa, which, although they are members of sect. Phalolepis , have close allies in sect. Acrolophus. The chromosome number of C. leonidia , 2 n  = 18, counted in root tips, is also reported and illustrated.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 146 , 375–383.

Notes are also presented on its ecology, biogeography and conservation status. In addition, the pollen characteristics and seed coat surface of H. turkmendaghensis and H. matronalis are examined by SEM.   © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society , 2005, 147 , 239–247.
