Five species are included in the genus Eremopyrum, namely, eum, um, artis, ale, and these, the first two are diploids with 2n = 14, while the rest are tetraploids with 2n = The karyotypes of the two diploid species are different from those of any other member, of the Triticineae in that they have chromosomes with extremely subterminal by: 7.

Eleven species (including 18 samples) of the genus Pyrenaria complex, i.e., Pyrenaria, Tutcheria and Pampyrenaria in the Camellioideae of the family Theaceae, were karyomorphologically investigated.

book, Caesalpinioideae and Papilionoideae were examined for polyploid divisions. Such divisions were frequently observed in all the species belonging to the Mimosoideae.

A comprehensive survey is presented of the cytology and taxonomy of the Sorghastrae, the term used to include the subgenera Eusorghum, Chaetosorghum, Heterosorghum, Sorghastrum, Parasorghum and Stiposorghum of the genus Sorghum, and the genus Cleistachne.

Chromosome morphology, numbers and associations in the Sorghastrae are compared. A cytological key is given to the species of Cited by: Cytotaxonomy is branch of taxonomy, which uses the characteristics of cellular structures, such as somatic chromosome to classify organism.

Improvement in the cytological techniques permit chromosomal studies. The Study of primate chromosome is another very active field, which provide very much information on relationships (chiarelli, ).

A statistical study has been made of the morphology of Holcus lanatus {zn = 14), H. mollis { = 28) and of three Fi progenies {zn = 21). The hybrids, while intermediate in some respects, tends to resemble the mollis parent strongly in morphology and growth form.

Cited by: Study of chromosome structure is very important in cytotaxonomic studies. It includes chromosome size, shape and position of centromere (i.e. arm-length ratio of each chromosome in the genome) Chromosomal size and shape are also important as taxonomic criteria in taxonomy. For examples, The chromosomal ratio if Mediola and Trillium of the family Liliaceae = Author: Robin Khan.

Abstract. Terrestrial or epiphytic, erect to pendulous herbs or climbers. Stems dichotomously branched, rarely with lateral branching, protostelic, with the xylem arranged radially or in parallel bands, or forming an almost closed cylinder (Phylloglossum).Leaves simple, with one simple vein, arranged in low alternating spirals or irregular whorls, or decussate, homophyllous or heterophyllous.

The following taxa were used: M. farinose, M. fruticulosa ssp. : Magda I. M. Soliman.Therefore, the present study aims to characterize and compare, at a cytotaxonomic level, the four varieties of the A.

magnifica complex. Thus, using representative sampling from the total of the geographic range of distribution, we expect to offer a suggested clarification of the taxonomic status of each variety within the complex.
