424 Harper : On the Flora of South Georgia 



Most of the herbaceous plants of moist pine-barrens have 

 conspicuous white, yellow, or pink-purple flowers. Among those 

 with white flowers are Dichrovicna (in this case it is the involucre 

 that is colored), Habcnaria ?iivea, and Sabbatia panicidata ; with 

 yellow, AletrtS) Gyrotheca, Poly gala cymosa, Hypericum myrti- 

 folium, H. virgatum, Chondrophora and Rudbeckia Mo/irii; and 

 with pink-purple, Limodorum, Rhcxia, Sabbatia campamdata, 

 Brezueria, Gerardia, Trilisa, and Coreopsis. As most of these 

 colored flowers, and several others not mentioned, can generally 

 be found in the same locality and at the same time, it follows 

 that these pine-barrens in summer present a very beautiful appear- 

 ance ; and, all things considered, they are most delightlful places 

 for the botanist. 



Lastly may be mentioned the plants of dry pine-barrens, 

 where the surface soil consists of dry sand. These are not of 

 great extent in Sumter County, and their flora is similar to that 

 of the dry sandy fields already mentioned. The following is a 

 list of some of the principal plants of dry pine-barrens : 



Pteris aqidlina L. 

 Pinus palustris M 



Ceanothus micro pity litis M 

 Vaccinia m staminenm L. 



Gymnopogon ambiguus (Mx.) Asclepias tomentosa Ell. 



B. S. P. Lacinaria elcgans (Walt.) Kuntze. 

 Crotalaria Pitrshii DC. tenuifolia (Nutt.) Kuntze. 



Cracca Virginiana L. Coreopsis lanceolata L. 

 Mcibomia arenicola Vail. delphinifolia Lam. 



Galactia erecta (Walt.) Vail. 



The four or five hundred species mentioned in the above lists 

 probably represent less than half the number of pteridophytes and 

 spermatophytes in Sumter County. 



Below I give an annotated list of species which are little 

 known, or are of interest on account of their distribution. 



As there are very few points in this part of the State whose 

 altitudes are known, I do not attempt to give the altitudinal dis- 

 tribution of each species. I will mention/however, that in the 

 city of Americus the altitude ranges from about 300 feet along 

 Muckalee Creek to 400 or more in the central portions of the city. 

 The altitude of the pine-barren region, about 10 miles southeast 

 of Americus is probably about 250 feet, and that of the Flint
