Abstract:
... An account of the discovery of the Albanian stenoendemic Asyneuma comosiforme and brief nomenclatural history of the genus Asyneuma provide a background for the re-assessment of recent molecular findings, which advocate the transfer of A. comosiforme to the genus Campanula. Objections to this transfer are raised, and additional morphological details and arguments are provided, highlighting the uni ...

Abstract:
... Large-scale changes in chromosome number have been associated with diversification rate shifts in many lineages of plants. For instance, several ancient rounds of polyploidization events have been inferred to promote genomic differentiation and/or isolation and, consequently, angiosperm diversification. Dysploidy, although less studied, has been suggested to also play an important role in angiospe ...

Abstract:
... The generic placement of Piptatherum kuoi (Poaceae, Stipeae) has long been controversial. Recent molecular phylogenetic analyses indicate that Piptatherum kuoi should be transferred to Patis. Here, we present cytological support for this transfer and discuss morphological differences and similarities. Piptatherum kuoi has a chromosome number of 2n = 46 with the chromosomes varying in length betwee ...

Abstract:
... Recent molecular phylogenetic studies indicate that Phaenospermateae and Duthieeae are among the early diverging lineages of Pooideae and that they are closely related to each other. Here, we test this with cytotaxonomical data. The monotypic tribe Phaenospermateae, represented by Phaenosperma globosum, has a chromosome number of 2n = 2x = 24 and a fairly symmetric karyotype consisting of 22 media ...

Abstract:
... The voles of the subgenus Microtus, which includes six species of the so-called “arvalis” group, have always been problematic for classification. Some group members differ in chromosome number and karyotype structure and yet appear morphologically indistinguishable, while others have very similar karyotypes despite exhibiting significant morphological differences. Two “arvalis” voles from Iran, M. ...
