Karyological notes on another eight species of Achillea (Asteraceae) from Turkey

The chromosome number and morphology in eight species of the sections Ptarmica (Mill.) W. D. J. Koch, Anthemoideae (DC.) Heimerl, Arthrolepis Boiss., Santolinoideae (DC.) Heimerl and Achillea of the genus Achillea L. (Asteraceae) were investigated using karyological techniques. Sample plants and seeds of A. biserrata M. Bieb., A. fraasii var. troiana Aschers. & Heimerl, A. multifida (DC.) Boiss., A. brachyphylla Boiss. & Hausskn., A. pseudaleppica Hub.-Mor., A. cretica L., A. latiloba Ledeb. ex Nordm., and A. kotschyi Boiss. subsp. kotschyi) were collected from natural habitats in 2003 and 2004. The chromosome number found in seven species was 2n = 18, while only A. kotschyi had 2n = 36. All chromosomes had median point (M), median region (m), and submedian (sm) centromers. In addition, only A. biserrata species had one subterminal (st) chromosome. An increase in asymmetry was not observed in the karyotypes of the species studied. None of the studied species had any B chromosomes.

Cirsium handaniae (Asteraceae), a New Species from Turkey

Cirsium handaniae Yıldız, Dirmenci & Arabacı (Asteraceae) is described as a new species from northeastern Anatolia, Turkey. It belongs to the section Epitrachys and appears to be close to C. macrobotrys and C. lappaceum s. lato. Diagnostic characters, as well as a full description and figures are provided. Its morphological characters are discussed and compared with the related species.

Achillea hamzaoglui (Asteraceae), a new species from Turkey.

Achillea hamzaoglui Arabaci & Budak sp. nova (Achillea sect. Santolinoidea), is described from Kirşehir Province, inner Anatolia, Turkey. It is compared with Achillea sintenisii and A. goniocephala. Diagnostic characters, as well as a full description, a key to related species and figures of new species are provided.

Karyological investigation of six Achillea L. (Asteraceae) species growing in Turkey

The chromosome number and morphology in six species of the sections Babounya (DC.) O. Hoffm. and Achillea of the genus Achillea L. (Asteraceae) were investigated using karyological techniques. Sample plants and seeds of A. santolinoides Lag. subsp. wilhelmsii (K. Koch.) Greuter, A. falcata L., A. magnifica Hub. - Mor., A. pannonica Scheele, A. crithmifolia Waldst. & Kit. and A. nobilis L. subsp neilreichii (A. Kern.) Formánek were collected from natural habitats in 2005. The chromosome number found in six species was 2n = 18. All chromosomes had median point (M), median region (m), and submedian (sm) centromers. An increase in asymmetry was not observed in the karyotypes of the species studied. None of the studied species had any B chromosomes.

Cirsium yildizianum (Asteraceae: Cynareae), a New Species from East Anatolia, Turkey

Cirsium yildizianum Arabacı & Dirmenci sp. nova (Asteraceae: Cynareae) is described from East Anatolia, Turkey. It belongs to the section Epitrachys and is morphologically close to C. macrobotrys and C. turkestanicum s. lato. It differs from them mainly in its habit, distinctly pedunculate inflorescence, capitula number and the features of the phyllaries.

Cypselar morphology of Carduus L. (Asteraceae) taxa in Turkey and its taxonomic implications

Abstract Cypselar morphology of 24 taxa including 16 species and eight subspecies of the 29 Turkish Carduus L. (Asteraceae) taxa (belonging to 17 species) were examined by stereomicroscope and scanning electron microscope. In this study, nine qualitative characters (cypselar shape, symmetry, kurtosis, surface ornamentation and different features of cypselar surface cells) and five quantitative characters (cypselar length and width, umbo length and width, ring diameter) were examined. Macromorphological studies revealed oblanceolate, narrowly obovate, narrowly oblong to oblong cypselar shapes with striate or furrowed surface. Based on scanning electron microscopic investigation of cypselar surface, the studied taxa were divided into five main types: scalariform, scalariform-ribbed, scrobiculate-ribbed, scrobiculate and scrobiculate-foveolate. An identification key of studied species based on cypselar morphology has been provided. The results indicate that cypselar features can be used as diagnostic taxonomic characters in examined Carduus species.

Cypsela morphology of Cirsium sect. Cirsium (Asteraceae) taxa in Turkey

In this study, the cypsela morphology of 21 (14 species) of the 28 (17 species) Turkish Cirsium Mill. sect. Cirsium (Asteraceae) taxa was examined by stereomicroscope and scanning electron microscope (SEM). The shapes of cypselas are oblong, obovate, narrowly obovate and oblanceolate. The taxa were divided into 7 main types according to the results of SEM investigation on cypsela surface characteristics as: scalariform, ribbed, scrobiculate-ribbed, scrobiculate, scrobiculate-reticulate, reticulate and bireticulate. Taxonomic significance of cypsela morphology is discussed. It is shown that cypsela features can be used as distinguishing characteristics in some Cirsium sect. Cirsium species.
