|Abstract:||'Ohi'a (Metrosideros polymorpha) is the dominant rain forest
tree species in Hawai'i. It has long impressed botanists for its morphological
variability and ecological amplitude. The present study has documented
differences in the distribution of Metrosideros polymorpha varieties in populations
of 'ohi'a growing on adjacent young and old flows. Pubescent varieties
are present on young volcanic substrates, but tend to be absent from older
soils in the rain forest zone. The genetic basis for these varieties has been
confirmed in a common garden experiment. The water relations of pioneer
and older forest '6hi'a have been examined and shown to differ, so that the
pioneer 'ohi'a tend to be able to maintain turgor at lower relative water contents
than the glabrous varieties.
