GENERAL NOTE: Not recorded by Cheeseman (1903) but common by the 1920s when Wilder studied the flora of Rarotonga. The Derris uliginosa of Cheeseman, a synonym of Derris trifoliata, was a mis-identification of the Millettia australis of the northwest hills of inland Rarotonga. A.C.Smith (Flora Vitiensis Nova) follows Verdcourt (1979) who concluded that Derris malaccensis was NOT native in New Guinea. [G.McC 11/2004]
