Plant Description:
Smallish tree adjacent a pull off area on West side of Kokee Road, 18 ft (6 m) tall with DSH of 16 cm. I suspect orignating from off-island koa planted by Foresters of yesteryear, fruits are smaller than other collections in area today, uniform in shape, and mostly undehisced. Lots of seed collected for KDOFAW seed bank and to screen for wilt resistance by HARC.
