Adansonii, the first two giving an indescribably weird and somber 

 aspect to the winter landscape. Other species noted at the same 

 time and place were three small trees, Salix nigra, Acer riibnnn 

 and Fraxinus caroli)iiana{T), one shrub, Baccharis Iialiviifo/ia, and 

 the following herbs (^all but one of them monocotyledons) : TypJia 

 latifolia, Limnobiwn Spongia, Sagittaria lancifolia, Zizania aquat- 

 ica, Pduiann gymnocarpon, Cladhim effnstini, Pontcdcria cordata 

 and Hibiscus sp. All of these have a pretty wide distribution, 

 being found also near the Georgia coast, though not associated 

 in the same way there, for these swamps seem to have no 

 counterpart much farther east. 



Whatevernatural plant-communities may have originally occu- 

 pied drier ground in the immediate vicinity of New Orleans have 

 probably long since disappeared, for dry land is of course at a 

 premium there. 



Leaving New Orleans on January 3, 1906, I went eastward 

 along the coast to Mobile, stopping about an hour and a half at 

 Gulfport, Mississippi. All along the Mississippi coast the pine- 

 barrens, which are rather flat, come very close to the shores of 

 the Gulf, sometimes within a few hundred feet. 



On the way to Mobile I first noticed Piuns Elliottii near Wave- 

 land, in Hancock County, Mississippi, Screnoa scrrulata on the 

 eastern shore of Bay St. Louis, in Harrison County, and Querciis 

 geniinata between Pass Christian and Long Beach, in the same 

 county. Whether these species extend farther west or not I am 

 not informed. All three of them, it should be observed, seem 

 to be almost confined to the Columbia sand, which is probably 

 not very well developed in Louisiana. 



At Gulfport,* where I had a few minutes in which to examine 

 the pine-barrens near the city, I could detect a faint development 

 of the same sort of topography which characterizes the Alta- 

 maha Grit region of Georgia, f Among the plants noted in the

f See Bull. Torrey Club 32 : 146. 1905. The descriptions of the topography, 

 vegetation, industries and other geographical features, in the soil survey of the Bil- 

 oxi area (which includes Gulfport and most of Harrison County) by Hearn and Carr 

 (Field Operations of the U. S. Bureau of Soils for 1904), would fit some parts of 

 southeast Georgia almost exactly.
