A new species of Viola L., Viola yildirimlii M. Dinç & Y. Bağcısp. nov. from South Anatolia is described and illustrated. It is found on the rocky slopes of Aladağ National Park, in the county of Adana, south Turkey, at an elevation of 1800 m. It belongs to Viola, subsect. Viola, and is similar to the Turkish endemics Viola isaurica Contandr. & Quézel and V. kizildaghensis M. Dinç & Ş. Yıldırımlı. Diagnostic morphologic characters for a detailed discrimination from two similar taxa and other Turkish Eflagellatae species are discussed. © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society, 2003, 141, 477–482.

A new species of Viola, V. kizildaghensis M. Dinç & S¸. Yi̇ldi̇ri̇mli̇, from Turkey is described and illustrated. It is found on the rocky slopes of Ki̇zi̇ldaǧ, Ki̇zi̇ldaǧ 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 Daǧ in the vilayet Muǧla; 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.

Reseda balansae Müll. Arg. (Resedaceae) is a very restricted and endangered Turkish endemic species known only from Mersin province (South Turkey), in a hotspot of biodiversity. It was first collected in 1855, and subsequently described in 1857. Afterwards, it was only collected once again in 1896. In this study we report the rediscovery of these two populations of R. balansae in Turkey more than 120 years after its last known collection. We provide a detailed revised description of this poorly known species and comments about its taxonomy (including designation of a lectotype), distribution and ecology. We also perform the first conservation assessment of the species at a global scale under IUCN categories and criteria, resulting in the proposal of the critically endangered category for the species, which apparently persists in one single population, since the type population has recently been destroyed.

This study was carried out to determine the flora of Çelikhan District (Adıyaman) and it’s near surroundings. 592 plant samples were collected from the research area. As a result of the evaluation of these plants, totally of 454 taxa were identified, including 295 genera belonging to 62 families. Of these taxa, 3 belong to Pteridophyta and 451 Spermatophyta divisions. Coniferophyta and Magnoliophyta subdivisions in the Spermatophyta division contain 2 and 449 taxa, respectively. It was determined that 449 taxa belonging to Magnoliophyta subdivision, belong to 385 Magnoliopsida and 64 Liliopsida class. It was determined that 30 taxa from the study area were endemic and the endemism rate was found to be 6.6 %. The distribution of taxa according to phytogeographic regions is as follows: Anatolian-Turan 158 (34.8%), Mediterranean 34 (7.5%), Euro-Siberian 33 (7.1%), multi-regional and unknown phytogeographical regions 229 (50.4%). The first five family according to the number of taxa; Asteraceae 42 (9.2%), Fabaceae 37 (8.1%), Brassicaceae 36 (7.9%), Lamiaceae 35 (7.7%), Poaceae 31 (6.8%). The first five genera according to the number of taxa; Astragalus 9, Silene 8, Salvia 7, Trifolium 6, Vicia 6. Within the scope of the study, a new and endemic onion species was discovered, named Adıyaman and this species was introduced to the literature as Allium adiyamanense Kılıç & Yıld.
