%X holocentric chromosomes of six species of rhynchospora, r. ciliata, r. pubera, r. riparia and r. barbata (2n = 10), r. nervosa (2n = 30) and r. globosa (2n = 36), were stained with cma3/dapi fluorochromes or treated with c-banding and sequentially stained with giemsa or cma3/dapi. variability in banding pattern was found among the species studied. heterochromatin was observed on terminal and interstitial chromosome regions, indicating that the holocentric chromosomes of rhynchospora show a heterochromatin distribution pattern similar to those plant monocentric chromosomes.
