Chromosome numbers in some vascular plant species of Argentina

Abstract

Somatic chromosome counts were made for 13 plant species from Argentina, including: eight species of Poaceae, and one each for Asteraceae, Boraginaceae, Caesalpiniaceae, Mimosaceae, Solanaceae. For two species of Poaceae — Agrostis inconspicua Kunze ex E. Desv. (2n = 28) and Poa chonotica Phil. (2n = 42), the chromosome numbers are reported here for the first time. A new cytotype for Bothriochloa springfieldii (Gould) Parodi (2n = 60) is also reported. Key words: chromosome numbers, vascular plants, Poaceae, Asteraceae, Boraginaceae, Caesalpiniaceae, Mimosaceae, Poaceae, Solanaceae, Argentina.
