Hibiscus: Rare native Hawaiian hibiscus, 1 by HawaiiBill

A friend gave my wife and me seeds for this rare native hibiscus. The flower is about the size of a quarter. It produces eight fuzzy seeds under each flower. Very leggy little plant but hardy and -- as I hope you agree -- has outstanding color. We have tried to find a definite species name but no one from Kaua`i to the Big Island is certain. Would appreciate knowing if you come up with something on that. Aloha and Mele Kalikimaka
