2. Abelia serrata Siebold & Zuccarini, FL Jap. I. 77, t. 34 (1835). 

 Linnaea serrata Graebner in Bot. Jahrb. XXIX. 133 (1900). 



Japan: Hondo, Siebold, K. Miyabe', Shikoku, Nanokawa, Tosa, June 11, 1888, 

 K. Watandbe; Kiusiu (Siebold ex Graebner). 



Abelia serrata has sometimes been confounded with A. uniflora R. Brown, but 

 that species is easily distinguished by its axillary, one-flowered or sometimes three- 

 flowered peduncles. The Chinese specimens identified by some botanists with 

 A. serrata belong to A. Graebneriana Rehder, a species closely related to A. uniflora, 

 but in foliage rather similar to A. serrata. 



3. Abelia Buchwaldii Rehder, n. comb. 



Linnaea Buchwaldii Graebner hi Bot. Jahrb. XXIX. 133 (1900). 



Japan: Hondo, Nagasaki, Maximomcz, 1863!, Ushiroyama, Mimasaki, S. 

 Arimoto, 1903. 



Graebner describes the sepals as ciliate, but I find them glabrous hi Maximowicz's 

 specimen, while in Watanabe's specimen of A. serrata the sepals are sparingly cili- 

 ate; Arimoto's specimen which has the sepals ciliate, is without flowers and I am 

 not sure whether it really belongs here or to the folio whig species; the akenes are 

 glabrous, but also in Maximowicz's specimen they are only very sparingly pilose 

 even in a young state. 



4. Abelia gymnocarpa Rehder, n. comb. 



Linnaea gymnocarpa Graebner hi Bot. Jahrb. XXIX. 134 (1900). 



Japan: Hondo, between Kioto and Maizura, Tomba, Doederlein (ex Graebner); 

 Adera, Shinano, J. G. Jack, September 5, 1905. 



I have not seen the type specimen, but Jack's specimen from Adera, which is 

 without flowers, seems to agree well with Graebner's description except that the 

 sepals are not strictly lanceolate.
