which is the only section where it has been possible to work out the 

 detailed distribution, is confined to the higher altitudes above 4000 

 feet, growing on exposed rocks and cliffs and on such sites is frequent 

 around the rim of the great amphitheater, which begins at Table 

 Rock Mountain and ends at the cliffs beneath Blowing Rock embrac- 

 ing the rocky slopes of Grandfather Mountain. The white flowered 

 form is not known to grow within this zone. 



Beginn ng on Buck Creek above Marion, N. C, and from thence 

 southward along the Blue Ridge to the headwaters of the Pacolet 

 River the white-flowered form is common and seemingly the only 

 early flowering form between altitudes of 1500 and 3500 feet. The 

 white flowered form by its definite distribution and its restriction to 

 lower altitudes seems to be sufficiently well marked to justify separ- 

 ating it as a variety from the rose purple-flowered plant. 



Rhododendron atlantictm Rehd. {Azalea ailcmUca Ashe) was 

 described from material collected near Georgetown, S. C, in 1910. 

 Specimens of this have recently been found in a package of plants 

 collected near New Berne, N. C, in 1896, and also specimens of R. 

 neglectum n. c. (Azalea neglecta Ashe, Bui. Tor. Bot. CI. 47: 5S1, 

 1920). These early flowering azaleas which have undoubtedly been 

 confused with Rhododendron viscosum should be looked for at other 

 points along the Atlantic Coastal plains. Both of them grow well 

 in cultivation at Washington, 1). C. R. atlanticum has a white 

 corolla rarely purplish in the bud and sometimes becoming purplish 

 as it wilts, its divisions much shorter than the very viscid-pubeseent 

 funnelfonn tube. 11. neglectum has a violet rose-colored corolla be- 

 coming whitish as it wilts, the narrow wide-spreading divisions as 

 long as tie villous, cylindrous tube, which is not glandular viscid.
