Hab. Gii'iin: Churei. 



Remarkable for nearly superior ovary and very narrowed sepals of the 

 fertile floAvers. Somewhat near Hydrangea Davldi Fbanch., but differs from it 

 by the more densely hairly leaves, peduncles, and longer sepals. Also 

 near H. Hemskyana Diels from which this is distinguisliable by the much 

 elongate leaves.
