This is not a species but instead a hybrid created during the 1960's. Dr. George Bunting wrote a paper on the plant naming it Philodendron domesticum Hort. (a horticultural name, not a species name) but stated in his paper he was not changing the name from Philodendron hastatum K Koch & Sellow.

They are two very different plants. For some reason in the 1960's growers liked to call this plant "Philodendron hastatum" but it never took the place of the actual species.
