don. sorry off topic, but I talked to some local flora specialists here. the e. koolauensis is endangered and are very susceptible to ohi'a rust (another rust disease associated with the ohi'a trees here). apparently need to be fungicide quite a bit to keep it going. on the other hand reinwardtiana is also considered native to Hawaii. both koolauensis and reinwardtiana referred to as 'nioi' in Hawaiian. fyi.
