Scaevola coriacea is a low, flat-lying perennial herb in the goodenia family (Goodeniaceae). Its older stems are somewhat woody, and the leaves are relatively far apart, giving the plant a sparse appearance. The succulent leaves of this plant are oval- to spoon shaped and are smooth or somewhat scaly with rounded tips. The flowers occur in branched clusters from the point of leaf attachment in groups of one to three "half-flower" looking yellowish green, lobed flowers.
Scaevola coriacea was historically found on 6 of the Hawaiian Islands but now only exists on Maui and two offshore islets with less than 300 individuals. Probably never very common, this species was listed as endangered in 1986.
