Chromosome numbers are published for the first time for H. cam- korijense subsp. rilae Rech. fil. & Zahn (4x), H. grabowskianum Nägeli & Peter (4x), H. haematopodum var. sudeticum Schack & Zahn (3x), H. lomniczkianum Szeląg (4x), H. pseudobifidum var. bucuranum Nyárady & Zahn (3x), H. umbellonigritum Szeląg (3x), H. wiesbaurianum subs. herculanum Zahn (3x), as well as six undescribed species belonging to the H. bifidum agg. (3x), H. caesium agg. (4x), H. umbrosum agg. (3x, 4x) and H. vulgatum agg. (3x) and a new supposed hybrid between H. bifidum s.lat. and H. murorum s.lat. (3x).

Abstract

Pollen morphology of 14 specimens from all nine Turkish native species along with one undescribed species of Cotoneaster was examined by light microscopy (LM) and scanning electron microscopy (SEM). The most frequent pollen types are trizonocolporate and tetracolporate, respectively and they occur together. Moreover, trisyncolporate, 3-parasyncolporate, 4-parasyncolporate, and pentacolporate pollen grains were observed in Cotoneaster for the first time in this study. Trizonocolporate pollen grains are radially symmetrical, isopolar, 22.5–35 × 26.25–42.5 μm in size and suboblate in shape. The amb is triangular, except C. integerrimus, which has a circular outline. Two endoaperture types can be distinguished. One is rectangular/square, the other is circular (endopore) and present only in C. integerrimus, C. melanocarpus and C. tomentosus. The exine pattern can be divided into two types, namely striate-perforate and rugulate-perforate. The quantitative pollen characteristics were analyzed using principal component analysis (PCA) and all pollen features were considered for hierarchical cluster analysis (HCA). Principal component analysis revealed that colpus width, endoaperture length, and endoaperture width are the most powerful metrical pollen traits in Cotoneaster identification. According to hierarchical cluster analysis, pollen traits enable division of Cotoneaster into two subgenera. The present study provides insights into pollen morphology of Cotoneaster, as well as its use for taxonomic purposes.

Instructions for authors

ACTA BIOLOGICA CRACOVIENSIA Series Botanica is an English-language journal founded in 1958, devoted to plant anatomy and morphology, cytology, genetics, embryology, tissue culture, physiology, biochemistry, biosystematics, molecular phylogenetics and phylogeography, as well as phytochemistry. It is published twice a year.

1. ACTA BIOLOGICA CRACOVIENSIA Series Botanica publishes original papers embodying the results of experimental or theoretical research, invited reviews, and brief communications. Manuscripts will be considered only on the understanding that they have not been published and are not being considered for publication elsewhere, that all authors agree on the content of the manuscript, and that laws on nature protection were not violated during the study.
Authors have to indicate their specific contributions to the published work in Authors’ Contributions and the sources of financial support of their research in Acknowledgements. They should clearly describe the following in their cover letter: (1) the aims and hypothesis of the paper; (2) the novelty of the paper − new achievements or innovations contained in the paper; and (3) the general significance of their paper.
Articles should be written in English (American spelling). Authors whose native language is not English are strongly advised to have their manuscripts checked by a professional translator or a native speaker prior to submission. Manuscripts should be written concisely. Purely descriptive studies, karyological notes on plants outside of central Europe, papers on economic botany as well as manuscripts of restricted interest generally are not considered for publication. In vitro studies which only describe protocols for plant regeneration without providing relevant biological information will not be considered for publication. A manuscript in the field of plant cell culture, physiology, biochemistry and phytochemistry must contain new insights that lead to a better understanding of some aspect of fundamental plant biology. They should be of interest to a wide audience and/or the methods employed should contribute to the advancement of established techniques and approaches.
Authors are charged a fee for publication of their articles. The bill for publication will be sent with the galley proof. The fee, which is calculated after all articles are accepted, will not exceed 20 USD per printed page for foreign authors and 70 PLZ per printed page for Polish authors. For the standard fee, color illustrations will appear only in the online version of the Journal. At authors’ request and for an extra fee, color illustrations may also appear in the printed version. While sending the manuscript, in the letter to the Editor, the authors should declare their contribution towards the extra costs and enumerate the illustrations which are to be printed in color.

2. Manuscripts should be submitted via the editorial manager: https://www.editorialsystem.com/abcsb

Manuscripts will be examined by at least two anonymous and independent refereeswho have declared that they have no conflict of interest with the author(s). Invitedreferees evaluate the manuscript according to the following criteria: (1) formalaspects, (2) originality, (3) importance in its field, (4) theoretical background, (5)adequacy of methodology, (6) results and interpretation, and (7) overall quality.

3. To shorten the review process, authors are asked to indicate 3 or 4 names of specialists working in the same scientific discipline outside of their institution (including the name of their institution and e-mail addresses) who could serve as reviewers of the manuscript. Manuscripts should be double-spaced, with lines numbered. On all points of style regarding text and tables, follow a current copy of the journal. Words to be italicized (scientific names of genus and species only) should be typed in italics.

4. Original papers should not exceed 8 printed pages (approx. 24 manuscript pages including tables and figures).

5. Original papers should be headed by the title of the paper, author’s name, institution, address, e-mail address of corresponding author(s) and short title (no more than 50 characters), and should be preceded by 5-10 Key words and a short Abstract. Original research papers should be divided into the following sections: Introduction, Materials and Methods, Results, Discussion, Conclusion, Authors’ Contributions, Acknowledgements and References.

6. Invited reviews are mostly of limited scope on timely subjects written for a general, well-informed audience. Invited reviews are solicited by the Editor. Ideas for unsolicited reviews should be discussed with the Editor. They are subject to the usual review procedure.

7. Brief communications are short papers (1–4 printed pages) reporting new findings that do not need a standard full-length treatment with the usual main headings. Brief communications are subject to normal review.

8. References in the text should be cited in the following form: Newton (1990) or Newton and Berrie (1982) or (Ward, 1950; Hiroshi and Ohta, 1970). For three or more authors, use the form Zinkowski et al. (1991) or (Zinkowski et al., 1991).
