1925) WILSON, THE RHODODENDRONS OF EASTERN CHINA 159 



All three appear to be plentiful in Chekiang province. R. Championae 

 Hook, for half a century considered endemic on Hongkong is now known 

 to grow as far north as the Chekiang-Fokien border. The other species 

 are little known and local in distribution, but our knowledge of the 

 flora of southeastern China is so fragmentary that it is unsafe to gen- 

 eralize. 



Of the 40 species known from this region three species are described 

 here for the first time. The subgenus Eurhododendron is represented 

 by 16 species, Azaleastrum by 7 species and the subgenus Anthodendron 

 by 17 species. Keys to the species are given but those for the subgenera 

 and sections are omitted since they are to be found in my account of 

 the Rhododendrons of Hupeh in Jour. Arnold Arb. V. 84-107 (1924).
