1922] Azalea in North Carolina 91 



A. atlantica hiteo-alha Coker. It is distinguished by its finely 



pubescent leaves. 

 A. viscosa glanca Ait. It differs from the type in its glaucus 



leaves. It should occur in the coastal plain. 

 A. viscosa tomentosa Hort. {A. tomentosa de G. Bot. Cult., 2nd. 



ed., 3 : 336. 1811). This has the leaves more or less pubescent. 



(Cumberland Co., near Manchester). 



A. viscosa hispida Wood. The branchlets are hispid. It has not 

 been found south of Pennsylvania but might occur in moun- 

 tain swamps in North Carolina. 



A. viscosa montana n. c. (Rhodode^idron v. var. Rehd. Azal., 



164. 1921), This has been found only in the mountains of 

 North Carolina. It differs from the type chiefly in the pu- 

 bescent winter buds. 



A. arhorescens Richardsonii n. c. {Rhododendron a. var. Rehd. 

 Azal., 168. 1921). This is a shrubby form which occurs on 

 the summits of high mountains in North Carolina. 



The following varieties which have been reported from further 

 south do not occur in North Carolina : 



A. canescens Candida n. c. (Azalea Candida Small. Bull. Torr. 



Bot. Club 28 : 360. 1901). Differs from the type in the glau- 



cescent and densely pubescent leaves. 

 A. serrulata georgiana n. c. (Rhododendron s. var. Rehd. Azal., 



156. 1921). This differs from the type chiefly in its densely 



pubescent winter buds. 

 A. viscosa aemulans n. c. (Rhododendron v. var. Rehd. Azal., 



165. 1921). This variety, which has been found only in Ran- 

 dolph County, Georgia, differs from the type chiefly in its 

 larger leaves. 



Note on Rhododendron — During the past year considerable additional information has 

 been seciired concerning the two small early flowering rhododendrons of the southern 

 Appalachians. Rhododendroru caroHnianum. Rehd., the rose flowered plant, is not uncom- 

 mon, particularly on dry standstone sites, in North Carolina and Tennessee to the north of 

 the French Broad river valley. To the south of this valley, and particularly to the south of 

 Mill Creek along the Blue Ridge at relatively low altitudes on moist cool sites, occurs the 

 white flowered plant. Rhododendron Margarettae n. c. (R. carolinictnum var. Margaretfae 

 Ashe, Rhod. 23: 177. 1921) which on account of its different habitat and distinct dis- 

 tribution can probably best be regarded as specific.
