170 JOURNAL OF THE ARNOLD AUGORETUM [vol. vi 



stamens about 10, shorter than corolla, filaments slender, more or less 



villose in lower half; pistil overtopping stamens, ovary cylindric, 0.5 



cm. long, furrowed, villose, style filiform, glabrous, stigma capitate. 



Fruit cylindric, 2 cm. long, 0.5 cm. wide, furrowed, verruculose. 

 Habitat: cistern China, Kwangtung and Fokien provinces. 



This species is characterized by its villose ovary, its glandular-villose 

 pedicels, often setose-glandulose petioles and by the curious serrations 

 of many of its leaves. Through the courtesy of the Herb. lirit. Museum 

 and of Kcw, I have on loan fragments of I lance's type and fr<>n the 

 Herb. Edinburgh I have on loan two specimens collected at Thai-yong, 

 some (50 miles west of Swatow by Dr. J. M. Dalzicl. In this herbarium 



is a specimen (No. 2667) collected on April 26, 1924, by II. H. Chung 

 in Inghok Hsien, Fokien province. This is all the material I have seen. 

 It agrees well and certainly all belong to the same species. Hayata in 

 describing his R. ciliato-pedicellat nm evidently overlooked I lance's 

 species. 



Rhododendron Henryi must be a pleasing and free-flowering species 

 well worth introducing into our gardens. It was discovered in March, 

 1881 by the Rev. B. C. Henry.
