The koki‘o from O‘ahu (Kokia lanceolata) has been extinct since the 1880’s. The last place it grew was on Koko Head Crater in the southeastern part of O‘ahu. Not much is known of this koki‘o, though it was perhaps "a small tree." A recent conversation with a local botanist revealed that although a thorough search of it in it’s former range has taken place, it resulted in no re-discoveries. It is quite possibly gone forever.

4. Kokia lanceolata Lewton
[Kokia drynarioides (Seem.) Lewton var. lanceolota (Lewlon) Rock]
(end, Ex)
Apparently small trees. Leaf blades 8-12.5 cm wide, 7-lobed, lower surface pubescent in axils of major veins near base, base subtruncate. Pedicels 3.5-5 cm long; involucral bracts narrowly oblong-lanceolate, 30-38 mm long, 8-13 mm wide, apex acute to subacuminate,. pubescent near base or glabrous; calyx 1.5-2 cm long, splitting irregularly, glabrous; petals and staminal column ca. 10 cm long. Capsules and seeds unknown. Originally known from southeastern O'ahu on the hills of Makaku and Koko Head and from Wailupe Valley, but apparently extinct since the late. 1800s or early 1900s.
This species was first noted by Hillebrand (1888) as Gossypium drynarioides Seem. var. ß.

Hillebrand found one tree on Oahu, with lanceolate bracts, which he called variety
Gossypium drynarioides ß. Mr. Lewton named this variety Kokia lanceolata on the strength of a few
scraps of lanceolate bracts in the Gray Herbarium. The writer does not think
it justifiable to create a new species on such incomplete material and more or
less on the strength that it grew on another island. The writer knows the Hawaiian
flora thoroughly, and is well acquainted with tremendous variations found
in all Hawaiian plants, and therefore prefers to retain the varietal rank rather
than specific. The plant in question has, however, become extinct.
