Rhododendron carolinianum Rehder, Rhodora 14: 99, 1912. 
A low compact evergreen shrub, with numerous branches, and 
sahara flowers in terminal deonaie the flowers opening before 
e development of the leaf-shoo The winter flower-buds are 
oo than half an inch long, ovoid, actibe: the scales densely ciliate 
and scaly. The leathery leaves are two to four and a half inches 
long and up to two inches wide, elliptic to oval, wedge-shaped at 
the base, acute or shortly acuminate at the apex, deep yellowish- 
green, Saar beneath, the upper surface at first sparsely scaly but 
ae ooth, the lower surface densely scaly, the petiole not more 
egy an inch long. Umbel-like clusters of four to ten flowers 
eae the branches, each flower on a scaly pedicel about half 
an inch long. ‘The sepals are short, equaling or shorter than the 
calyx-tube, ee rbicular to broadly ovate, scaly and often 
ciliate. The roll is rose-colored, sometimes paler or nearly 
white, about = “qaeh long and one and a half inches broad, abrotts; 
or sometimes rather sparingly scaly, the tube Lig equalin

the filaments rose-colored, hairy at the base. The glabrous os 
is purple, a little shorter than the stamens. The ovary is scal 
The naerwaly oblong aude is brown and about half an inch long. 
For many years this interesting plant has been known as Rhodo- 
dendron punctatum. In 1912 Alfred Rehder announced that there 
were really two species which had been bearing this name. It 
has been pretty well established by him that the original Rhodo- 
dendron punctatum of Andrews is the same as Rhododendron minus 
Michx., a name published in 1792, six years earlier, and to be used 
on account of its priority. That plant is distributed from South 
Carolina to Georgia and Alabama. The other species which has 
been included in Rhododendron punctatum is the one here illustrated. 
‘Its range is more restricted, being confined apparently to the 
mountainous region of eastern Tennessee and western North and 
South Carolina. It resembles the other species, but can be readily 
distinguished by the short bell-shaped corolla-tube, not exceeding
