Abstract

Abstract: The present paper reports the chromosome numbers and karyotypes in 9 species of 5 genera from China. It is found that all these analysed species are diploid. The karyotypes of most species are made of m and sm and of a few of st chromosomes. These are grouped into four types, 1A, 2A and 1B, 2B. Blyxa is the most primitive, and Hydrilla is the most advanced.

Key words: Hydrocharitaceae, Blyxa, Hydrilla, Ottelia, Vallisneria, Hydrocharis, Chromosome
