Readily distinguished from the Philippine Hydrangea lobbii INlaxiin., hy its 

 entire or nearly entire, elongated leaves, which are not barbate in the axils 

 beneath. It seems to be most closely allied to the Formosan H. Integra Hayata, 

 but has smaller leaves, four petaloid sepals to the outer flowers instead of two, 

 and is apparently an erect shrub, not scandent.
