Senna gaudichaudii, also known by many common names, including kolomana in Hawaii[2] and as blunt-leaved senna in Australia, is a species of flowering plant in the family Fabaceae and is native to some Pacific Islands including Hawaii, parts of Southeast Asia and Queensland in Australia.

[2][3][4] This species was first formally described in 1832 by William Jackson Hooker and George A. Walker Arnott, who gave it the name Cassia gaudichaudii in The Botany of Captain Beechey's Voyage.

[5][6] In 1982, Howard Samuel Irwin and Rupert Charles Barneby transferred the species to the genus Senna as S. gaudichaudii in Memoirs of the New York Botanical Garden.

[1] In Hawaii, this species inhabits dry, sheltered locations on rocky slopes, and disturbed sites.

[2] In Australia, the species grows in forest and drier places in rainforest in coastal and subcoastal eastern Queensland and Cape York Peninsula.
