|A. sandwicense||Artificial Hybrid||D. plantaginea|
This artificial intergeneric hybrid bears a striking similarity to the greensword, A. grayanum. Silverswords and Dubautia plantaginea are sympatric on both E Maui and W Maui where greenswords occur, suggesting the possibility of this sort of origin for A. grayanum. The mean pollen stainability of two individuals of this combination was 29%. The maximum chromosome pairing configuration observed in this combination was 11II + 1 M6.
