Abstract: The genus Charpentiera (Amaranthaceae), found in the Hawaiian and
Austral archipelagoes, has a structurally gynodioecious but functionally dioecious
breeding system. The sex ratio varies from taxon to taxon within the genus. The
sex-determining mechanism is unknown. A high rate of ovule sterility is found in all
the taxa, which i~ not predicted by the pollen sterility figures reported. Data concerning
seed size, pollen size, and seed germination potential are provided. Hybridization
is demonstrated to occur between Charpentiera densiflora Sohmer and C. elliptica
(Hilleb.) Heller. Reproductive isolation is reported for C. tomentosa var. tomentosa
Sohmer and C. obovata Gaud.
