Remarkable for nearly superior ovary and very narrowed 
sepals of the fertile flowers. Somewhat near Hydrangea Davidi 
Francu.; but differs from it by the more densely hairy leaves, 
peduncles, and hairy longer sepals; also near H. Hemsleyana DrEts, 
from which this is distinguishable by the much elongated leaves.
