Remarkable for nearly superior ovary and very narrowed 

 sepals of the fertile flowers. Somewhat near Hydrangea Davidi 

 Feanch.; but differs from it by the more densely hairy leaves, 

 peduncles, and hairy longer sepals ; also near H. Hemsleijana Diels, 

 from which this is distinguishable by the much elongated leaves.
