Hab. in sylvis primaevis insulae Javae, ad 50 — 1200 M ait. supra mare. 



The species belongs to ihe section Diplolohus. It differs from al its 

 allies by its tripartite leaves. It was discovered in tlie year 1911 by a 

 native coUector in the Island Noesa Kambangan, south of Java at + 50 M. 

 above sealevel and introduced from there in the Buitenzorg Botanical Gard-
