This species was described in 1933, originally as a variety of the Subcordate Melanthera (Wollastonia subcordata (A. Gray) Orchard) from the island of Hawai’i.

The Poplar-leaved Melanthera is known only from the type material that was collected in 1918 somewhere in the Maunalei Valley on the island of Lana’i in the Hawaiian Islands, it is now considered extinct. [1]
