Closely allied to A. uniflora R. Brown, which is easily distinguished by its sub- 

 coriaceous glabrous leaves, the 1-3-flowered inflorescence at the end of elongated 

 branchlets and the more campanulate corolla with a shorter and wider tube. Abelia 

 Graebneriana is somewhat variable in foliage and also in the flowers; the most dis- 

 tinct forms are represented by the following three numbers: No. 267 differs in its 

 narrower glabrescent leaves usually only with one to three teeth on each side, the 

 narrower ones being about 4 cm. long and 1 cm. broad, in the longer sepals, the 

 larger corolla, nearly 3 cm. long with longer and slenderer tube, and in the lateral 

 flowering branchlets being usually reduced to fascicles of leaves; No. 2020 has 

 ovate, indistinctly crenulate-serrulate leaves, obtusely acuminate, and smaller 

 flowers, scarcely exceeding 2 cm. in length; No. 4380 has much smaller leaves not 

 exceeding 2.5 cm. and oval sepals, the flowers are wanting. 



To this species is probably related Linnaea serrata, var. Hegii (Graebner 

 [p. sp.] in sched.) Pampanini in Nuov. Giorn. Bot. Ital. n. ser. XVII. 722 (1910) 

 from Shensi, G. Giraldi, and from Hupeh, Mts. of Fan-sien, C. Silvestri (No. 1825), 

 chiefly characterized by ciliate sepals puberulous on the outside; it is possibly a 

 distinct species.
