<I>Commelina benghalensis</I> L and <I>C. caroliniana</I> Walter, two allied weedy species of the Commelinaceae vary in their breeding and meiotic systems. The former is predominantly auto- and the latter facultatively xenogamous. Meiotic system of <I>C. caroliniana</I> also provides for higher recombination index, characterized as it is by high chromosome number and higher chiasmata frequency: On the contrary <I>C. benghalensis</I> has fewer chromosomes and closed breeding system for which reason it generates little genetic variability. This difference qualifies <I>C. benghalensis</I> as a "specialist" and <I>C. caroliniana</I> as a "generalist"
