A new species of Rhaponticoides Vaill., Rhaponticoidesaytachii Y. Ba?c?, Do?u & Dinç sp. nov. collected by the authors from south Anatolia, is described and illustrated. The new species is restricted to deprived Quercus forest openness around Dumlugöze‐Sar?veliler (C4 Karaman). Diagnostic morphological characters from R. amplifolia (Boiss. & Heldr.) M.V.

Haplodontium zangii X.R.Wang & J.C.Zhao,sp. nov. (Bryaceae,Bryopsida) from Xizang,China

Haplodontium zangii X.R.Wang &; J.C.Zhao, a new moss species from Xizang, China, is described and illustrated. Previously, specimens of H. zangii have been identified as Mielichhoferia himalayana Mitt. However, H. zangii is distinctly different from M. himalayana in having excurrent costae with short awns (vs long denticulate awns), short-pyriform capsules, 0.8–1?mm (vs long-pyriform capsules, 2.5–3?mm), and densely papillose exostome teeth (vs smooth or vertically striped exostome teeth). Haplodontium zangii is similar to H. macrocarpum (Hook.) J.R.Spence, which was traditionally placed in Mielichhoferia Nees &; Hornsch. as M. macrocarpa (Hook.) Bruch &; Schimp. The main differences between H. zangii and H. macrocarpum are in the morphology of the leaves, capsules, guide cells, and stomata. Mielichhoferia himalayana and another Chinese species of Mielichhoferia, M. sinensis Dix., are also transferred to Haplodontium Hampe, a new genus in the bryoflora of China, as H. himalayanum (Mitt.) X.R.Wang &; J.C.Zhao and H. sinensis (Dix.) X.R.Wang &; J.C.Zhao. A morphological comparison and a key to the three species of Haplodontium in China as well as to H. macrocarpum, a species that is likely to be found in China, are provided.     

Klasea serratuloides subsp. karamanica subsp. nov. (Asteraceae), from the central and south Anatolia transition zone,Turkey

A new subspecies, Klasea serratuloides (DC.) Greuter & Wagenitz subsp. karamanica B. Dogan & A. Duran (Asteraceae), is described and illustrated from Anatolia, Turkey.

It is morphologically similar to K. serratuloides subsp. serratuloides. Diagnostic morphological characters from closely similar taxa are discussed and arranged in a key. Ecology and conservation status of the subspecies is also presented. In addition, the geographical distribution of the new subspecies and other related species is mapped. The pollen morphology and achene surface of K. serratuloides subsp. karamanica and K. serratuloides subsp. serratuloides were examined by SEM.

Chaenorhinum semispeluncarum sp. nov. and C. yildirimlii sp. nov. (Scrophulariaceae) from east Anatolia,Turkey

Chaenorhinum semispeluncarum H. Y?ld?r?m, Kit Tan, S. ?enol & A. Pirhan sp. nov. and C. yildirimlii Kit Tan, H. Y?ld?r?m, S. ?enol & A. Pirhan sp. nov. (Scrophulariaceae, C. sect. Microrrhinum) from east Anatolia are described and illustrated. They are both narrow endemics related to the rare C. cryptarum, also from east Anatolia. Chaenorhinum semispeluncarum occurs on calcareous marl rich in potassium nitrate at the entrance of wet caves in Malatya and differs from C. cryptarum by its erect habit, smaller corollas, shallowly ribbed and tuberculate, bicoloured seeds. Chaenorhinum yildirimlii from the neighbouring province of Erzincan was found on alluvial soil of stream banks and differs from C. semispeluncarum by its seed characters which are similar to those of C. cryptarum. Chaenorhinum yildirimlii differs from C. cryptarum, most conspicuously by the violet lower corolla lip spotted dark purple at the apex.     

Comparative analysis of C-band karyotypes inCrepis praemorsa subsp.praemorsa and subsp.dinarica

Crepis incarnata subsp.dinarica (G. Beck)Hayek is nowadays considered as a subspecies ofC. praemorsa (L.)Tausch. Comparative analyses of Feulgen karyotypes demonstrate great similarities, but remarkable differences in the presence and the distribution of the constitutive heterochromatin in the two taxa are detected by using the Giemsa differential staining technique (C-banding). This favours their specific distinctness.

Bosch &; Lac., C. pseudogracilis Card. &; Dix. with C. goughii (Mitt.) Jaeg., C. caudatus (C. Müll.) Mont., C. reduncus (Reinw. &; Hornsch.) Bosch &; Lac. and C. trachythecius (C. Müll.) Jaeg. with C. comosus (Reinw. &; Hornsch.) Bosch &; Lac., C. herzogii Broth., C. subtricolor Lor. and probably also C. nodijlorus (C. Müll.) Jaeg. with C. aureus Bosch &; Lac., C nietneri (C. Müll.) Jaeg. with C. involutusz (C. Müll.) Jaeg., C. subgracilis Ren. &; Card. ex Gangulee and C. latinervis (Mitt.) Jaeg. with C. gracilis (Mitt.) Jaeg., and C. laetus (Mitt.) Jaeg. with C. savannarum (C. Müll.) Mitt. C. pterotoneuron (C. Müll.) Jaeg. is reduced to a variety of C. umbellatus (Arn.) Par. The occurrence of C. exasperatus Brid. on Sri Lanka could not be confirmed. Campylopus flagelliferus (C. Müll.) Jaeg. is reported as new to Sri Lanka.

The Old World species of Pouzolzia (Urticaceae, tribus Boehmerieae). A taxonomic revision

The Old World species of the genus Pouzolzia have been revised and 24 species and 13 infraspecific taxa recognised. Worldwide, the genus now totals 36 species and 17 infraspecific taxa. Pouzolzia sect. Memorialis Bennett & Brown (including the genera Gonostegia Turcz. and Hyrtanandra Miq.) is maintained here as a section of Pouzolzia. The characters used to separate Pouzolzia from Boehmeria are found to work worldwide. In the Old World, the genus ranges, west to east, from Senegal to Japan and the Solomon Islands, and, north to south, from China, the Himalayas and Yemen to South Africa, Madagascar, Australia and the Lord Howe, Norfolk and Kermadec Is. Some species are common and occur almost throughout tropical Indomalesia or are widespread in Africa; others are rare and with a narrow range, for example restricted to one or a few oceanic islands. Each of the taxa occurring in the Old World is described and illustrated, habitats and geographical ranges are indicated, conservation status is discussed on the basis of our impression of old and new collecting activity, and distributions are mapped. The following new taxa are described: P. tsaratananensis Friis & Wilmot Dear from Madagascar, P. herpetophyton Friis & Wilmot‐Dear from the Comoro Is., and P. zeylanica subsp. calcicola Friis & Wilmot‐Dear and P. thailandica Friis & Wilmot‐Dear, both from southern Thailand. A new name, P. variifolia Friis & Wilmot‐Dear, is proposed for P. heterophylla (Blume) Wedd., nom. illeg. The following new combinations are published here: P. australis (Endl.) Friis & Wilmot‐Dear, P. sanguinea (Blume) Merr. var. formosana (Li) Friis & Wilmot‐Dear, P. sanguinea (Blume) Merrill var. cinerascens (Blume) Friis & Wilmot‐Dear, P. mixta Solms var. shirensis (Rendle) Friis & Wilmot‐Dear, P. hirta (Blume) Hasskarl var. parvifolia (Wight) Friis & Wilmot‐Dear, P. pentandra (Roxb.) Benn. & R. Br. subsp. wightii (Benn. & R. Br.) Friis & Wilmot‐Dear. and subsp. wightii (Benn. & R. Br.) Friis & Wilmot‐Dear var. gracilis (Miq.) Friis & Wilmot‐Dear. The following taxa are reduced to synonymy for the first time: Pouzolzia argenteonitida W.‐T. Wang, P. bracteosa Friis, P. calophylla W.‐T. Wang & C.‐J. Chen, P. guineensis Benth. var. seyrigii Leandri, P. guineensis Benth. var. madagascariensis Wedd., P. baronii Leandri, and P. auriculata Wight.
