* 18. R. BI'COLOR G.Don. (A. (N.) BI' COLOR Pum fi.) The two-co\Qured-Jlowered 



Azalea. 



Identification. Don's Mill., 3. p. 847. 



Synonymes. Azalea bicolor Purtth Fl. Amer. Sept., 1. p. 153.: Azalea nudiflora var. bicolor Ait. 

 Hort. Kew., \. p. 319., Trew Ehret., 48. 



Spec. Char., #c. Leaves oblong, clothed on both surfaces with fine hoary 

 pubescence, not bristly on the nerve. Flowers small, not clammy, naked. 

 Tube of corolla hardly longer than the segments. Calyxes very short j 

 having one of the segments linear, and 4 times longer than the rest. Fila- 

 ments exserted. Branchlets hispid. (Don's Mill., iii. p. 848.) The flowers, 

 which are slender, and smaller than those of most of the species, are of a pale 

 rose colour, or nearly white, with a deep-red-coloured tube. The plant is u 

 native of Carolina and Georgia, on barren sandy hills ; where it forms a 

 shrub growing from 3 ft. to 4 ft. high, and flowering in May and June. It was 

 introduced in 1734, and is frequent in British gardens; though it does not 

 appear to us to deserve to be considered in any other light than as a va- 

 riety of 72. nudiflorum.

Spec. Char., fyc. Leaves oblong, pubescent on both sur- 

 faces, but afterwards hairy. Flowers large, not clammy, 

 rather naked. Teeth of calyx oblong. Tube of corolla 

 hairy, shorter than the segments. (Don's Mill., iii. p. 

 847.) The plant is indigenous to North America, from 

 Pennsylvania to Carolina ; where it forms a shrub 

 from 2 ft. to 6 ft. high, and producing its yellow, red, 

 orange-coloured, or copper-coloured flowers from May 

 till June; which, according to Pursh, is without ex- 

 ception, the handsomest shrub in North America. 



Varieties. 



3fe R. c. 2 Mortem Swt. Fl.-Gard., 2d s., 10., is a hybrid between R. calen- 

 dulaceum and one of the red varieties of R. nudiflorum, of which 

 there are two subvarieties ; one with a flesh-coloured corolla, having 

 the upper segment orange-coloured, edged with flesh-colour, called 

 R. Mortem carneum ; and another, called R . MortenV var. pra/stans, 

 with pale copper-coloured flowers, tinged with blush. 



afc II. c. 3 fu/gidum Hook., A. c. fulgida //or/., has the corollas of an 

 orange-red colour, with bright green leaves, which spread out be- 

 neath the corymbs of flowers, and form a rich background to th^m.
