Calpigyne has hitherto been a monotypic genus known only from the 

 original collection or collections, as Blume in describing it in 1856 records 

 it from both Borneo and* Celebes. The original species Calpigyne frutescens 

 Blume has apparently not appeared in recent collections, or if so it has

 particulars* yet the present species conforms in essential generic characters 

 to those given by him. Calpigyne hainanensis differing from C. frutescens 

 in its chartaceous, crenate or crenulate-serrate leaves. The staminate 

 calyces in the present species are equally or subequally 3-lobed (not 4-
