This species is closeh- related to Kadua acuminata Cham. tS: 

 Schl., but is very different in appearance. Its leaves are larger 

 and more typically acuminate than K. pctiolata Gray, while its 

 flowers are pure white, the latter species having greenish flowers. 

 The corolla is considerably longer and larger than in these two 

 species.
