There certainly is no difficulty in distinguishing this 
species from the two previously described ones. ‘Those 
have very numerous, small leaflets and Jacqueshuberia 
amplifoliola (as the epithet implies) has relatively very 
large and fewer leaflets; there are also abundant floral 
characteristics to separate the species. The nearest rela- 
tive of the new one is Jacqueshuberia quinquangulata 
which has pubescent ovaries, deeply sulcate branchlets, 
etc., in addition to the very different leaves.
