Self-incompatibility in Cordyline kaspar (Agavaceae)

Abstract The tree from which the type material of the Three Kings cabbage tree (Cordyline kaspar W. R. B. Oliver) was taken is shown to be self-incompatible, setting few seeds when pollinated by its own pollen. It sets abundant seeds when pollinated by Cordyline australis pollen, and by pollen from one of its own seed progeny. This latter plant is believed to be a hybrid between C. kaspar and C. australis; it, and other putative hybrids, show a leaf form intermediate between the two presumed parents.

Keywords Cordyline kaspar; Cordyline australis; self-incompatibility; Agavaceae
