in the driest positions. The grasses are Stcnotaphntm ameri- 

 caiiKin, which is much used in Charleston as a lawn grass, Cyno- 

 doH Dactylon, also a good lawn grass, Leptochloa fascicularis, 

 Sporobobis indicns and Panicuiii lannginosuui. Stropliostylcs lui- 

 vola and Galactia volubilis are the principal vines. The herbs 

 noted were Moiiarda punctata, Eiipatoriiini Iciicolcpis, Galiinn 

 hispididiiin, Bidcns frondosa, Saiiicula canadensis and species of 

 Mciboniia. In Fig. 4 is shown a part of this hammock growth. 

 In center is a live oak, with a cedar to left. The shrubs are 

 Callicarpa to right, Fagara Clava-Hcrculis in front of oak, and 

 Myi'ica caro/incnsis to left. In foreground is the grass Leptochloa 

 fascicularis, through which is running the vine Stropliostylcs 

 helvola. 



The Salt Flats and Marshes. — On the north side of the island 

 the character of the shore varies considerably. Towards the 

 western end there is a low sandy plain just above high-tide mark 

 which is covered with an association of fva frutesccns, Borrichia 

 frutescens and several species of sedge. A few scattered clumps 

 of Myrica project above the general level, and the pretty little 

 Sabbatia stcllaris adds dashes of color at intervals. Just beyond 

 this sandy plain and separated abruptly from it by a line of drift 

 is a low flat of sandy mud covered at high tide by a few inches 

 of water. This flat is covered with a dense and beautifully level 

 growth of Borrichia frutescens and Sporobolus virginicus in almost 

 pure association. The Borrichia stood about one foot high, the 

 Sporobjlus about six inches. Among these was a little Salieornia 

 anibigua and Aster subulatiis. This growth ends abruptly and is 

 followed by a dense strip of pure Salieornia andngua about twenty 

 feet wide. Adjoining this, in the black wet inud, commences the 

 extensive marsh-grass [Spartina patens) flats which stretch across 

 to the mainland. 



Tow.ird the east, the Hoi-riehia-Sporobolus fiat just mentioned 

 ends rather abruptly in a shghtly lower and more muddy area, 

 when the growth changes quickly to an inner strip of Spartina 

 poiystachya and an outer strip of Sporobolus 7'irginicus, both of 

 quite pure growth. At one point on the back beach was noticed 

 a fine lot of Sesu7'iu)n Fortulaeastrun/.
