... Anthemideae (Asteroideae: Asteraceae) is one of the well-represented tribes in Egypt, where some 12 genera with twenty-eight species are native to the country (Zareh, 2009). The identification and nomenclature of genera and species are treated here as considered by Fedorov (1961), Yavin (1970), Feinbrun-Dothan (1978, Herman et al. (2000), Ghafoor and Ali (2002), Zareh (2005), and powo. ...
Achene diversity of 12 genera with 22 species of the tribe Anthemideae was studied using light and scanning electron microscopy. These genera are Achillea L., Anacyclus L., Anthemis L., Brocchia Vis., Chlamydophora Ehrenb. ex Less., Cladanthus Cass., Cota G. Jay, Cotula L. Glebionis Cass., Matricaria L., Tanacetum L., and Tripleurospermum Sch.Bip. A description of the achene of each species, a key to the investigated taxa based on morphological and anatomical features, as well as drawings of cross sections, are provided, and SEM micrographs of achenes are provided. Macro‐ and micro‐morphological criteria concerned with achenes were investigated, and the taxonomic relationships between the studied taxa were discussed.
... The achenes of Anthemis are obovoid to obconical, circular or quadrangular in cross-section, usually with c. 10 smooth or tubercular ribs. There are few reports about the anatomy, classification and seed morphology of Cota (Metcalfe and Chalk, 1957;Zareh, 2009;Bani and Adıgüzel 2010;Ghafoor, 2010;Özbek et al., 2011). Moreover, there are some studies about chemical composition and antimicrobial activity of the closely related genus Anthemis L. (Uzel et al.,2004;Çelik et al., 2005;Uysal et al., 2005;Albayrak and Aksoy, 2012). ...
Anthemis section Cota was accepted as separate genus recently. Genus Cota is represented by 24 taxa in Turkey. Some of them have economic importance because of their uses for various purposes such as obtaining drugs, food and dye. etc. In this study, Cota melanoloma subsp. melanoloma, C. melanoloma subsp. trapezuntica and C. antitaurica were studied morphologically and anatomically. Three of them are endemic to Turkey. C. antitaurica is only known from the type locality and critically endangered species, while C. melanoloma is distributed in only northern Anatolia. As the results, the diagnostic characteristics, synonyms, flowering and fruiting times, habitat properties, distributions and threat categories of each taxon are presented. The most important morphological characteristics for more proper discrimination the species are determined as the shape of capitula and palea, indumentum of stem and leaf. The detailed anatomical studies indicate the diagnostic characteristics as both hair and vascular bundle length and pith of the stems, hair length and length/width ratio and the type of stomata of the leaves, the layer number of parenchymatic ray cells and the cortex length of the roots.
... According to Täckholm (1974), Chrysanthemum sensu lato in Egypt is represented by 11 genera and 31 species. Several species are very rare and have become difficult to find in their natural habitat (Täckholm, 1974;Zareh, 2009). ...
Giemsa C-banding was applied to the chromosome complements of six diploid species belonging to six genera in Chrysanthemum sensu lato (Anthemideae) distributed in Egypt. Four types of C-banding distribution were observed in the taxa as follows: (i) negative C-banding in Anacyclus monanthos (L.) Thell.; (ii) all bands in terminal regions in Achillea fragrantissima (Forssk.) Sch. Bip, which showed 32 bands on 18 chromosomes; (iii) all eight bands at centromeric regions on eight chromosomes in Matricaria recutita L.; and (iv) bands at terminal and centromeric regions in Brocchia cinerea Vis. (12 terminal and six centromeric bands on 12 chromosomes), Cotula barbata DC. (four terminal, six centromeric, and eight short arm bands on 16 chromosomes), and Glebionis coronaria (L.) Cass. ex Spach. (eight terminal on the short arms and four large bands in centromeric regions on 12 chromosomes).
