Pseudostellaria tianmushanensis G. H. Xia & G. Y. Li, collected from the Tianmu Mountains Nature Reserve in northwestern Zhejiang, China, is described and illustrated. This new species is similar to P. rupestris Pax., but differs by having a string of fusiform or ovoid‐globose tubers, leaves that are narrow elliptic‐lanceolate, glabrous, with cuneate base with scattered multi‐nodulate hairs, papillate margins and basipetalous variation in floral morphology. Moreover, the seed tubercle ornamentation also supports the recognition of the new species. A key to the species of Pseudostellaria in Zhejiang province is provided.     

A new species of Silene (Caryophyllaceae) from South Anatolia, Turkey

Silene doganii A.Duran & Y.Menemen sp. nov. from the Amanos Mountains (C6: Osmaniye-Turkey) is described and illustrated.

A new species of Silene (Caryophyllaceae) from east Anatolia, Turkey

Silene bitlisensis O.Tugay & Ertugrul from the Green Line Afforestation Zone (B9: Bitlis Province) is a new species described and illustrated here. It is closely related to S. caramanica Boiss. & Heldr. var. ilarslanii Aytaç & Dural, from which it mainly differs in its habit, leaf, and floral features.  © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 463–466.     

Salvia siirtica sp. nov. (Lamiaceae) from Turkey

Salvia siirtica Kahraman, Celep & Do?an sp. nov.(Lamiaceae) is described and illustrated as a new species from the northern part of Siirt province in southeast Anatolia, Turkey, where it was found growing in open forests of Quercus. It is morphologically similar to S. indica L., but differs by having densely glandular pilose to villous stems and petioles, close verticillasters, smaller flowers, clearly concave calyx apices, entirely white corollas and smaller nutlets. Salvia siirtica and S. indica are also distinguished by their nutlet and pollen micromorphologies, illustrated by SEM images. The nutlet surface of S. siirtica is very finely wrinkled and its pollen has 3–4 primary lumina per 25 μm², compared to 5–8 in S. indica. Conservation status assessment, distribution map, and notes on biogeography and ecology of the new species are provided.
