Alectryon macrococcus
Alectryon macrococcus, known as Alaalahua or Māhoe in Hawaiian, is a species of flowering tree in the soapberry family, Sapindaceae, that is endemic to Hawaii. Alectryon macrococcus var. auwahiensis has been found growing naturally only (endemic) in Maui, where it grows in Hawaiian tropical dry forests on the south slope of Haleakalā at elevations of . It is threatened by habitat loss. Alectryon macrococcus var. macrococcus inhabits mesic forests at elevations of  on Kauai, Oahu, Molokai and western Maui. These trees can reach  tall. Their leaves are each made up of oval-shaped, asymmetrical, net-veined leaflets. Variety auwahiensis has leaflets with rusty-red undersides. The fruits contain a seed with a bright red aril. The arils are sweet-tasting and were food for native Hawaiians. The seeds also attract rats, whose consumption of them prevents the plants of this endangered species from reproducing. The black twig borer (Xylosandrus compactus) destroys the twigs. References
