 This is a very vari- 

 able and much-cul- 

 tivated species, and 



the following varieties are often described as species. 



(1) Lrs. lanceolate or elliptic, acute, g-S in. long, dull 

 above and rtifonsly strigose : shrubs. SS ft. 

 high, somewhat loosely branched. 



Var. Kaempferi, Rehder. Lvs. deciduous, only a few

 3:261. — Prom this variety nearly all of the beautiful 

 garden forms of the Indian Azaleas have originated by 

 cross-breeding with other varieties and forms of .^ . 

 Indica introduced from Japanese and Chinese gardens, 

 and by hybridizing, especially with .,1. rosmarinifdlia. 

 To this variety may be referred the following re- 

 markable forms : Var. crispifldra. Van Houtte. Pis. 

 large, rose-colored, with distinctlv crisped segments.

 balsaminafldra, Varr. A. Rdllissoni. Hort.).Lvs. ob- 

 long-lanceolate: fls. salmon-red, very double, with im- 

 bricated, oblong segments, resembling the blooms of a 

 camellia-fld. balsam. P.M. 19:418. Gn, 18:249.
