Ruhus Enslenii Tratt. 



In good soil in woods, Laurel Land, Hartsville, S. C. April 

 24, 1910. This is the one-flowered plant considered by some a 

 form of R. procumhens, and I can find no record of its occurrence 

 in South Carolina. The typical R. procumhens is found in Chapel 

 Hill, N. C, where it forms dense mats in wet nlaces. 

 Carex texensis (Torr.) Bailey. 



It covers the ground under trees, in the yard of Dr. A. A. 

 Kluttz, Chapel Hill, N. C. So far it has not been published 

 from either of the Carolinas, but Homer D. House has collected 

 it at Clemson College, S. C. It is now known from Southern 

 Illinois to the Carolinas, Georgia, and westward. 



This plant makes a good substitute for grass on lawns that are 

 damp and densely shaded. 

 Oenothera Drummondii Hook. 



This beautiful evening primrose was collected in very sandy 

 soil along the trolley way on Sullivan's Island, S. C, Aug. 28, 

 1909. It has been collected from this island before (Herbarium 

 of the New York Botanical Garden) and from Ormond, Florida 

 (Gray Herbarium) but I cannot find that it has been reported 

 from South Carolina or Florida, or indeed collected from any 

 other of the Southern States east of Texas. 

 Chapel Hill, North Carolina.

In several previously published papers* I recorded a number

 to light through exploration in southern Florida, and are as 

 follows: Serenoa serrulata, Quercus Rolfsii, Chrysohalanus pello- 

 carpus, Alvaradoa amorphoides, Suriana maritima, Cicca disticha, 

 Mangifera indica, Rhus leucantha, Ilex Krugiana, Hibiscus Rosa-
