Reasons: Narrowly endemic to two adjacent peaks in the northern Waianae Mountains of Oahu. The three currently known populations contain a total of fewer than 40 plants. The primary threats to the species are feral pigs and alien plants.
Comments: Threats include alien vegetation and trampling from feral animals (especially pigs) and humans, and overcollection.

Alsinidendron trinerve (also called Three Nerved Alsinidendron) is a species of flowering plant in the carnation family, Caryophyllaceae, that is endemic to island of Oʻahu in Hawaii. It is a subshrub, reaching a height of 30–80 cm (12–31 in).
Three-Nerved Alsinidendron inhabits mixed mesic and wet forests on the slopes of the Waiʻanae Range at elevations of 900–1,230 m (2,950–4,040 ft). Associated plants include pilo (Coprosma spp.), ʻapeʻape (Gunnera petaloidea), ʻalani (Melicope spp.), hāpuʻu (Cibotium spp.), hame (Antidesma platyphyllum), and māmaki (Pipturus albidus). It is threatened by habitat loss.
