Puff (Opera Bot. Belg. 3: 207-292. 1991) noted that this species has the largest leaves of the genus, as well as notably large flowers and fruit, and sometimes has "conspicuously fissured bark" that is also distinctive. W. C. Ko (in FRPS 71(2): 114. 1999) described the corolla lobes as 3-lobed, but this has not been mentioned by any other authors.
