Both this plant and U. pedicellata grow at Penang, and it seems 
impossible to be certain which of them Dr. Hunter had before him when 
he described his Nauclea schlerophylla, but his description agrees better 
with this plant than with the other.

Specimens of this species from various localities frequently have 
monstrous flowers. This species is called Uncaria acida in the Leiden 
Herbarium, and U. ovalifolia in the Kew Herbarium. There can be 
little doubt that both names are equally accurate, on the whole perhaps 
U. acida is preferable. There is no specimen of this plant in the 
Kew Herbarium from Sumatra or Java. ‘
