Chromosome Studies in Argentinian Species of Mimosa (Leguminosae).

CHROMOSOME STUDIES OF IRANIAN MEMBERS OF TRIBE SOPHOREAE (FAMILY LEGUMINOSAE

The tribe Sophoreae sensu Polhill [9,10] is a large and diverse assemblage comprising the ancient and primitive ancestral stocks of Papilionoideae. The most frequent chromosome basic numbers in this tribe are x = 11 and x = 9 but chromosome numbers range from x = 8-14 are also known. In this study chromosome numbers and karyotype variation of Iranian members of tribe Sophoreae are reported. Ira...

The evolutionary history of Mimosa (Leguminosae): toward a phylogeny of the sensitive plants.

PREMISE OF THE STUDY Large genera provide remarkable opportunities to investigate patterns of morphological evolution and historical biogeography in plants. A molecular phylogeny of the species-rich and morphologically and ecologically diverse genus Mimosa was generated to evaluate its infrageneric classification, reconstruct the evolution of a set of morphological characters, and establish the...

COUSINIA PAPILLOSA, A NEW SPECIES FROM EASTERN IRAN, INCLUDING CHROMOSOME COUNT AND PALYNOLOGICAL STUDIES

Cousinia papillosa (Asteraceae) from eastern Iran is described and illustrated as a new species. Differences between the new species and its closest relative, C. meshhedensis, are discussed. A map showing the distribution of the two species is given. The scanning electron micrography of the pollen grains shows obvious differences between the two species especially in the sculpturing of exine. T...
