Etymology

This species is named for Maria Johanna van Steenis-Kruseman (1904-1999) in recognition of her prodigious bibliographical and biographic work. All students of the flora of Southeast Asia are indebted to her for her exhaustive research on publications, maps, and collectors, much of it presented in volume 1 of Flora Malesiana (;the Green Bible'; van Steenis 1950) and supplements to volume 5 (Van Steenis 1956, 1958) and volume 8 (1974).
