Kokia lanceolata

Kokia lanceolata (Wailupe Valley treecotton) was a species of flowering plant in the Malvaceae family. It was the only species of Kokia to occur on the island of Oahu. Originally known from the hills of Makapu'u, Koko Head and Wailupe Valley. It became extinct not long after its discovery in the 1880s, most likely due to grazing pressure from cattle and goat ranching.
