to the known flora of the mountains and to that of Alabama at 

 the same time. 



This plant seems to be a biennial, and the leaf-character above 

 mentioned does not appear in the flowering and fruiting speci- 

 mens on which the original description was based, but I had 

 noticed it at the New York Botanical Garden in 1903, in some 

 plants raised from seeds of the type-specimens collected the year 

 before. (The same plants flowered in 1904 and have probably 

 since died.) 



With the umbellifer was Dianthera Americana L., a charac- 

 teristic plant of such situations, and in shallow rocky pools close 

 by Orontimn aquaticnvi L., both of which seem not to have been 

 reported from this part of the state before. (The altitude of this 

 point, it should be observed, is about 1 150 feet above sea-level, 

 according to the topographic maps of the U. S. Geological 

 Survey. ) 



At the same place was also a Xyris, as yet unidentified, though 

 it is in all probability the same as one reported from Lookout 

 Mountain by Dr. Mohr under the name of X. flexiiosa Muhl. 

 \\\ small areas of moist sand just above the rocky bed of the 

 creek I noticed y//;/(r//j' rcpcns Michx. and Gratiola pilosa Michx., 

 two more additions to the known flora of the mountains, though 

 I had once before found the latter in the metamorphic region of 

 Georgia.* 



On flat rock outcrops a short distance away from the creek 

 were noticed Crotonopsis linearis Michx. and Arenaria brevifolia 

 Nutt., both of which are very characteristic of flat granite out- 

 crops in ^Middle Georgia and are also known on Altamaha Grit 

 outcrops in the pine-barrens of Georgia. f 



On the way back from Town Creek still another surprise 

 awaited me in the shape of several specimens of Polygala nana 

 (Michx.) DC. in full bloom (it probably flowers throughout the 

 year or nearly so) in dry woods between Chavies and the brow 

 of the plateau. This, too, was previously known only from the 

 coastal plain.
