Rhododendron minus is chiefly distinguished from R. carolinianum 
by the longer cylindric corolla-tube which is longer than the lobes, 
by the corolla being lepidote outside and the upper lobe being dis- 
tinctly spotted. The habit of the plant is much looser and more 
straggling with longer and slenderer branches and the leaves are 
larger and comparatively narrower and more pointed. 
The type locality of Rhododendron minus seems to be the same as 
that given for R. Cuthberti, for Michaux mentions in his Journal under 
the entry for November 11, 1788, among the plants observed near 
Augusta, Georgia, on the banks of the Savannah River an unnamed 
Rhododendron and again under December 4 he records in the vicinity 
of Seneca (Oconee Co.) a Rhododendron species nova which is without 
doubt the same. As Michaux refers the deciduous Rhododendrons 
to Azalea, the only other species of Rhododendron growing in this 
region is R. maximum with which Michaux of course was perfectly 
familiar; the unknown species therefore could not have been any 
other than R. minus. As Michaux in his first description of R. minus 
does not mention the flowers and as he states that it grows on the 
banks of the river Savannah, it is most likely that his description is 
based on the specimens collected in November, 1788, near Augusta. 
The leaves of the plant cultivated in Europe as R. punctatum are 
generally somewhat smaller and narrower than those of the wild speci- 
mens from Georgia, but in the shape of the corolla both plants agree 
perfectly. 
In Banks County, Mr. T. G. Harbison has collected a form of Rhodo- 
dendron minus with considerably larger flowers, which seems worthy 
of being introduced into cultivation on account of its much more
