This tree is cultivated in Hort. Bog. sub n. XI-C-106A and XI-H-27; unfortunately duplicates of several other numbers (XI-I-10, 20 & 50) have been distributed under this name also; they, however, all belong to Dolichandrone serrulata (WALL. ex DC.) SEEM. The mention of this N. Sumatran endemic tree, (as 'Heterophragma macrolobium* = Haplophragma macrolobum (Miq.) Steen.) by is derived from a mis- identification; the specimens belong to the common Radermachera glandulosa (Bl.) Miq.
