1925J WILSON, THE RHODODENDRONS OF EASTERN CHINA 181 



near Giran. U. Mori in April, 1909, is given as the collector in both 

 instances. On my visits to Formosa I did not see this Azalea; it is not in 

 cultivation.

This new Azalea is easily recognized by its relatively large flowers, its 

 5 stamens with villose filaments and pilose style. It is most closely re- 

 lated to R. Simsii Planch, which has from 8 to 10 stamens. In my 

 Monograph of Azaleas with only the description to guide me I had con- 

 fused this new species with the small flowered R. breviperulatam Hayata.
