Melanesia (Solomon Isl. and New Hebrides); in Malaysia: Admiralty Isl., Louisiades.

Notes

The specimen of Grether & Wagner has fertile branches more like those of L. dimorphum than is usual in L. trifurcatum, and has one branch intermediate between sterile and fertile; the fully sterile leaflets are smaller than normal in L. dimorphum and only slightly cordate at the base. The two species are very closely allied, and it may be that in the Admiralty Islands, where their areas of distribution overlap, there has been hybridization.
