Résumé :	Studies were made of the morphology and karyotype of accessions of H. asper, H. cannabinus and H. surattensis. There were six simple epicalyx segments in H. asper, nine in H. cannabinus and ten branched and leafy epicalyx segments in H. surattensis. Karyotypic analysis of the species showed a preponderance of median centromeres. H. surattensis had a more symmetrical karyotype and smaller chromosomes than H. asper and H. cannabinus. H. asper had the longest chromosomes. Ten of their chromosomes were significantly different in length, while four were significantly different in arm ratio.
