Alectryon macrococcus, known as ʻAlaʻalahua or Māhoe in

pinnae. The pinnae are smooth, glossy and net-veined, 4 to 10 inches long and 2 to 5 inches. Fruits are from 1 to 3 inches in diameter with a single black seed embedded in a red, fleshy aril.[3]

Their leaves are each made up of oval-shaped, asymmetrical, net-veined leaflets. Variety auwahiensis has leaflets with rusty-red undersides.[4] The fruits contain a seed with a bright red aril. More than a century ago, it was noted that Native Hawaiians ate the fleshy, insipid and slightly sweet arils and mildly flavored seeds.[5]native Hawaiians.[4] The seeds also attract rats, whose consumption of them prevents the plants of this endangered species from reproducing.[4] The black twig borer (Xylosandrus compactus) destroys the twigs.[6]

Alectryon macrococcus var. auwahiensis has been found growing naturally only (endemic) in Maui, where it grows in

habitat loss
.

Alectryon macrococcus var. macrococcus inhabits mesic forests at elevations of 365–1,035 m (1,200–3,400 ft) on Kauaʻi, Oʻahu, Molokaʻi and western Maui.[9][10][11][12]
