Tiller leaf anatomical features of nine Alopecurus species collected from high mountainous areas in Turkey were evaluated the present study. Detailed descriptions studied taxa and an identification key generated using are given. Clustering principal coordinate analysis (PCA) methods applied based on a total 14 characters. Anatomical differences between detected characters taxonomic interest ide...

in this research, the effect of air pollution on proline concentration, soluble sugar, anatomical and morphological features was studied in two plant species malva parviflora and hordeum glaucum in 2009. the area of the stand steel factory of khuzestan was considered as the polluted site and shush region was considered as the control site, and sampling was carried out from the two sites, accide...

leaf anatomy of 27 species of potentilla l. (rosaceae), representing 9 sections and four related genera, especially tylosperma botsch., schistophyllidium (juz. ex fed.) ikonn., drymocallis fourr. ex rydb., and sibbaldia l. from iran were studied using light microscopy. the most outstanding characters of blade and midrib were measured. the result revealed a number of taxonomically important char...

About 170 species of Commelina are known from tropical and subtropical regions of the world. Nepal contributes 6 species of Commelina to the world flora. In the present work, taxonomy of all the six species of Commelina reported from Nepal (C. benghalensis, C. caroliniana, C. diffusa, C. maculata, C. paludosa and C. suffruticosa) was studied. Voucher specimens were collected from Central and Ea...

Grammosciadium pterocarpum subsp. bilgilii and Grammosciadium pterocarpum subsp. sivasicum from Turkey are herein described as two new subspecies, and the species Grammosciadium schischkinii is synonymied under Grammosciadium pterocarpum subsp. pterocarpum. Quantitative variation of morphological and anatomical characters have been analysed to provide discriminative characters between the taxa ...

A study of the leaf anatomy in the species of the genus Festuca present in the Iberian Peninsula was made. A total of 68 taxa were included and 15 characters were measured in leaf cross-section. The major anatomical features of each taxonomic group were characterized, and some variability was observed in the taxa. The anatomical patterns observed were compared and discussed with the relationshi...

Wood anatomy is an important source of systematically informative character information that can and should be used in cladistic phylo­ genetic analyses ofrelationships in flowering plants. However, the re­ sults ofa cladistic analysis are only as good as the characters and obser­ vations, which together comprise the data set that is analyzed. The goal of this paper is to address the former of ...

A new species of the Plectopylidae, Gudeodiscus longiplica is described from northern Guangxi Province, southern China. The shell, anatomical and radular characters are figured and described. This new species is characterized by long plicae on its parietal shell wall, which have not been observed in any other Gudeodiscus species. In contrast, the long parietal plicae are characteristic for the ...
