CHROMOSOME NUMBERS IN SOME VASCULAR PLANT SPECIES FROM ARGENTINA

摘要

Somatic chromosome counts were made for 13 plant species from Argentina, including: eight species of Poaceae, and one each for Asteraceae, Boraginaceae, Caesalpin iaceae, Mimosaceae, Solana-ceae. For two species of Poaceae — Agrostis inconspicua Kunze ex E. Desv. (2n = 28) and Poa chonoti-ca Phil. (2n = 42), the chromosome numbers are reported here for the first time. A new cytotype for Bothrio-chloa springfieldii (Gould) Parodi (2n = 60) is also reported.
