not prove hardy in Great Britain or here.* It was first raised in cultivation 
here from seed sent in the autumn of 1910 by T. G. Harbison. Plants were sent 
to Kew in November, 1916 and to you this autumn. 
Rhododendron calendulaceum. Michaux, in the Flor. Bor. Am. (i. 151), 
described a variety of his Azalea calendulacea as var. flammea. This 
is certainly a distinct species (not yet described) which is common in dry oak 
woods near Augusta and Milledgeville, Georgia. Michaux no doubt found it 
near Augusta, as he passed by that place several times on his journeys from 
Charleston to the high Appalachian Mountains. It is a low-country plant, while 
R. CALENDULACEUM is found Only on mountain slopes. 
It is probable that Michaux sent seeds of R. flammeum to Europe, and I 
suspect that the bright red colour found in some of the hybrid Azaleas raised in 
Belgium was due to the influence of that species. I have no knowledge that 
flowering plants exist in Europe at this time. It was first raised here from seeds 
collected by myself near Augusta, in 1914. The flowers of this Azalea are more 
brilliantly colored than those of any other species, and there is a chance that it 
ma}^ prove hardy in some parts of Great Britain. Plants were sent to Kew, 
Gomer Waterer, J. C. Williams and F. R. S. Balfour in 1916, and to you 
this autumn. 
Azalea prunifolia. Small, was first collected in flower in July, 1903, by 
Roland M. Harper, two miles northwest of Cuthbert, Randolph County, Georgia. 
Cuthbert is in a warm region, but notice how late this plant flowers. Seeds 
collected at the type station by T. G. Harbison have been sent to you. 
Azalea oblongifolia. Small. This is a common plant in southern Arkansas 
and eastern Texas. Small, in his Flora gives Tom Green County, Texas, as the 
type station. This is evidently a mistake, as Tom Green County is in the semi- 
desert part of Texas where Azaleas cannot possibly grow. The type station is 
no doubt in sandy bogs, Grapeland, Houston Count 3 ^ Texas. This plant has 
usually been referred in herbaria to R. viscosum. It is probabty a distinct 
species. Seeds collected for the Arboretum by A. G. Palmer have been sent to 
you this autumn. 
Azalea serrulata. Small, is based on a specimen (No. 967), collected b}' 
George B. Nash, in June, 1894, in the vicinity of Eustis, Lake County, Florida, 
and distributed by him as Azalea viscosa. I have seen only a photograph of 
the type specimen, but judging by the locality, it would not be surprising if this 
turns out to be a good species. I hope to get flowers and fruits next year. 
4. I have no information of any hybrid American Azaleas having been raised 
by American nurserymen, but in 1915 seeds were sown here of what is supposed 
to be a hybrid between R. calendulaceum and R. occident.\le crossed in the 
Arboretum. For literature of the hybrids raised in Europe see the Bradley 
Bibliography, III., 661. 
5. Cultivation, etc. Judging by our experience here, all the species which 
we have tried flourish in ordinary soil on well-drained slopes. Swampy 
• It has survived the past winter quite well at Kew, and one of the plants 
carries flower buds.—W. J. Bean.
