Hab. Fokien: Kosan, leg. S. Nagasawa, Aprili. 1910. (No. 258.) 

 Diifers from the type by the much larger bracts which are so large as 

 <3auline leaves. Petals are usually in a transitional stage between stamens 

 and themselves. They have very often an anther-cell on one side. I could 

 find but one normal petal out of several which I examined in many 

 flowers.
