    Abstract

    The European H. secalinum (2n = 4x = 48) and the South African H. capense (2n = 4x = 28) had similar karyotypes with ten pairs of metacentrics, three of submetacentrics, and one of SAT-chromosomes. The C-banded karyotypes of H. secalinum from northern Europe were characterized by banding patterns with few bands, those of H. secalinum from Spain and H. capense by banding patterns with more bands. The bands were mostly small or very small and had no preferential disposition. Intraplant banding pattern polymorphism was observed in North European H. secalinum, in agreement with an outbreeding reproductive system. No banding pattern polymorphism was present within plants of H. secalinum from Spain and H. capense, suggesting self-pollination. In both species banding pattern polymorphism was prevalent among plants. Together with other evidence the fairly similar basic C-banded karyotypes of the two species indicate a rather close relationship.
