4. Ilysanthes refracta (Ell.) Beath. 



Lindernia refracta Ell., Sketch Bot. S. C. and Ga. 1: 579. 1821. "Grows 

 around the margins of ponds in Barnwell district, South Carolina; in 

 Burke County, and near Milledgeville, Georgia." Type, "Hab. in 

 sphagnis, Barnwell Co., So. Car.," seen in Elliott Herbarium at the Charles- 

 ton Museum. 



Tittmannia monlicola Spreng., Syst. 2: 800. 1825. " Carolina' bor. {Lin- 

 dernia monticola Nutt.)." The name of Nuttall was a nomen nudum, 

 and Nuttall (Gen. Am. 1: 9. 1818) says, perhaps due to a typographic 

 slip, "from the hills of New Hampshire." But that the name monticola 

 was in use before the date of Sprengel's publication is proven by the 

 existence of old specimens labeled "Lindernia monticola" collected by 

 Schweinitz probably in North Carolina. Such a specimen, in the her- 

 barium of Columbia University at the New York Botanical Garden, is 

 probably an isotype of T. monticola, and is Ilysanthes refracta. 



Ilysanthes refracta (Ell.) Benth., in DC. Prod. 10: 419. 1846. 



Moist sandy soil, shallow depressions in pineland, in the Coastal 

 Plain from South Carolina to northern Florida and eastern Alabama;
