1. In several flowers of NGF 31983, 33447 only 5 or 6 stamens were found. Close study revealed that in those cases several stamen pairs grew together to form one stamen.
2. Hoogland & Craven 10909 probably belongs to this species, although it has rather large leaves (petiole 4-6 cm long, rachis 14-16 cm long) with many (8) leaflets. NGF 33447 has leaves with long petioles (4-6 cm long); its leaflets are the largest seen in this species (7.5-11.5 by 2.5-3.5 cm).
