Melicope ovalis
Federally endangered tree in the Rutaceae family, endemic to Kipahulu Valley in Haleakalā National Park on Maui, confined to a single known population, with opposite leathery elliptic leaves and capsules whose carpels are fused along nearly their entire length, growing in wet montane forests.
Common Names
Alani, Hana Melicope, Wild Pelea, Alanis
Summary
Hana melicope is a Maui native tree occurring in Kipahulu Valley within Haleakalā National Park, in koa- and ’ohi’a-dominated montane wet forests at 850–1,430 m. It grows up to 5 m tall; new growth is covered with fine brown hairs that later become hairless; leaves are opposite, leathery, broadly elliptic, 8–16 cm long and 4–10 cm wide with 3–4 cm petioles and hairless surfaces; bruised foliage has an anise odor. Inflorescences bear 3–7 flowers on stalks 10–13 mm long; fruit is a capsule about 10 mm long and 13–15 mm wide; seeds are glossy black and about 5 mm; exocarp/endocarp are hairless; distinguished by carpels fused along almost their entire length, with nonpersistent sepals and petals and well-developed petioles.
Conservation and cultivation considerations include a federally endangered status with a single known extant population in Kipahulu Valley, Haleakalā National Park; threats from habitat degradation, feral pigs, and competition from alien plants such as Hilo grass and strawberry guava; management involves barrier fences, pig removal, alien plant control, and seeds provided to the National Tropical Botanical Gardens for propagation.
