Hawaiian flower, thought extinct, rediscovered by a drone
HONOLULU -- Researchers dispatched a drone into the Hawaiian skies to observe an extremely biodiverse area on a remote part of Kauai's Kalalau Valley. The scientists soon realized they had rediscovered a flower species that was thought to be extinct. According to a statement from the National Tropical Botanical Garden, Hibiscadelphus woodii was discovered on a vertical cliff face. Most sections of this area of the valley are inaccessible to humans because of the steep landscape.
