conditions are not needed for the successful cultivation of R. canadense and 
R. VISCOSUM, although they grow naturally only in swamps. 
At Marshall, in eastern Texas, there is an Azalea, of which we have seen only 
a fruiting specimen, which seems distinct. This and semialata are the only 
American species of which there is any knowledge which have not yet been 
introduced. 
I hope these notes will be of some service to you, and if I can help you further 
do not fail to call on me. 
Faithfully yours,

21s^ December, 1917. 
Since this letter was written I have received Mr. W. W. Ashe’s description 
in Vol. XIII., page 26, of the Bulletin of the Charleston Museum 
(April, 1917) of his 
“ Azalea atlantica sp. nov.—A stoloniferous shrub. The fragant flowers, 
in compact cluster of 4-10, are rose-purple, or reddish, 2’5-3 cm. long, the lobes 
short, pointed, and scarcely one-half the length of the slender glandular- 
pubescent tube; stamens 5, exserted, slightly longer than the lobes, style 
4‘5-5 cm. long. Twigs when young sparingly pubescent with short spreading 
hairs, becoming gray and glabrous the second season. Leaves 4-6 cm. long, 
obovate, mucronate and abruptly acute at the apex, cuneate at the base, pale 
beneath, pubescent on the midrib and ciliate in the margins. Pine barren 
swamps, north-eastern South Carolina. Type from near Georgetown, S.C., 
collected by W. W. A. in May and June, 1916. In many respects this plant 
suggests A. viscosA L., A. arborescens, Pursh, or A. prunifolia. Small. 
Although it occurs in a region traveled by the elder Michaux, he does not seem 
to have noticed it, nor does it seem to be any of the forms proposed by Don 
or Pursh.” 
We have also received at the Arboretum sterile branches of an Azalea with 
broadly obovate to elliptic leaves and very slender bright red branchlets which 
cannot be referred to any of the described species. This Azalea is described as 
“ a straggling shrub in upland woods.” It was collected by T. G. Harbison at 
Biloxi, Mississippi, near the shores of Mississippi Sound, on October 30, 1917.

It is necessary to state that at present Mr. P. D. Williams is now going 
through a number of old catalogues and articles on American Azaleas and their 
hybrids, and hopes to contribute any extracts he may consider of importance 
to the Rhododendron Society Notes for 1919. 
We are indebted to Mr. W. J. Bean for reading through the following article.
