 and counties, in alphabetical order, follow. 



Alabama 



Autauga County.- — In this Coastal Plain county Silene 

 Wherryi was first discovered by Dr. Roland M. Harper on 

 April 22, 1928, in moderately rich woods about 2 miles southwest 

 of Booth. On April 28 Mr. Benedict and I found it sparingly in 

 open oak woods on gravelly soil 4 miles southeast of Marbury, 

 near the northeastern corner of the county, the soil reaction 

 proving to be subacid. 



Bibb Co. — A large colony of the plant was observed on 

 April 25 on wooded slopes 4 miles north of Centerville. This 

 locality is in the Appalachian Valley physiographic province 

 close to the Fall Line, and the rock is sandstone, the soil being 

 minimacid. 



Cullman Co. — The specimen from Cullman cited by Mohr^ 

 under the name Silene caroliniana is now in the National 

 Herbarium, and proves to represent the new species. We were 

 unable to locate any Silene in that region. 



Elmore Co. — On thinly wooded sand-hills just below the 

 Fall Line about 8 miles east of Wetumpka this Silene was found 

 in abundance on April 27, the soil reaction proving to be sub- 

 acid. It is associated with a dwarf Phlox, which had been dis- 

 covered there by Dr. Harper in July, 1927, and which was found, 

 on examination of the few flowers remaining in late April, to 

 represent the species listed in Small's Flora of the Southeastern 

 L'nited States as P. Hentzii Nuttall, not definitely known else- 

 where in the State. 



Etowah Co. — In the National Herbarium there is a specimen 

 from Gadsden, although we did not find any there on this trip. 



Jefferson Co.- — The steep sandstone ridges around Birming- 

 ham support extensive colonies of this Silene, and we collected 

 it on April 28 on the southeast side of Shades Mountain about 

 5 miles south of the city. The reaction was again subacid. 

 Dr. Harper also reports observing it from the train between 

 Monmouth and Trafford in this county. 



Marshall Co. — In describing Silene Wherryi as a new species, 

 Dr. Small designated as type the best preserved specimen in the 



2 Plant life of Alabama, 497. 1901.
