CHROMOSOMES OF WOODY SPECIES

Abstract

Chromosome numbers of nine subtropical woody species collected in Argentina and Paraguay are reported. The counts tor Coutarea hexandra (2n=52), Inga vera subsp. affinis 2n=26 (Fabaceae) and Chorisia speciosa 2n=86 (Bombacaceae) are reported for the first time. The chromosome number given for Inga semialata 2n=52 is a new cytotype different from the previously reported. Somatic chromosome numbers of the other taxa studied are: Sesbania punicea 2n=12, S. virgata 2n=12 and Pilocarpus pennatifolius 2n=44 from Argentina
