This is the plant issued by Wallich as No. 4141 of his Catalogue under the name D. macrophylla. Being different from the older D. macrophylla of Blume, a new name had to be found for it. This was done by De Candolle, who reduced it, as a variety, to Wallich's D. undulata with the type specimen of which in Wallich's own herbarium it does not agree. De Candolle was followed by Hiern, Kurz, and Clarke; we now restore it to specific rank. The true D. undulata, Wall., is a Burmese species. It is found also in the Andaman Islands, but it has not as yet been collected in Malaya.
