ALTAMAHA GRIT REGION OF GEORGIA 313 



The treatment of the cellular cryptogams which constitute 

 the remainder of this catalogue is necessarily less complete than 

 that of the vascular plants. Their bibliography has not been as 

 carefully investigated as has that of the higher plants since the 

 nomenclature reforms of recent years, and consequently in some 

 cases I have not been able to cite the place of publication cor- 

 rectly. For local distribution in Georgia in most cases I can 

 only cite localities for specimens collected, for I am not suffi- 

 ciently familiar with these plants to identify many of them in the 

 field. Most of the mosses have been determined by Mrs. Eliza- 

 beth G. Britton, the hepatics by Miss Caroline C. Haynes, and 

 the fungi by Dr. W. A. Murrill, and their assistance is hereby 

 gratefully acknowledged. 



Our knowledge of the general distribution of most of these 

 plants is very fragmentary, for they are not usually mentioned 

 in local floras, and consequently many of them are known only 

 from the comparatively few stations where they have been col- 

 lected. For this reason I have not attempted to give the total 

 range in every case. 



The number of cellular cryptogams known in the region will 

 of course be considerably increased by future field work. It has 

 been my custom while in the field to collect all bryophytes and 

 woody fungi which I was not sure I had already, and there may 

 not be over twice as many of these in the region as are listed here. 

 The fleshy and parasitic fungi remain almost untouched, but 

 it is not likely that they are very numerous, mainly for the same 

 reasons noted by Kearney (Contr. U. S. Nat. Herb. 5:314. 1900) 

 on the coast of North Carolina and Lloyd &. Tracy (Bull. Torrey 

 Club 28:81. 1901) on the coast of Mississippi. The lack of 

 shade in the pine-barrens is unfavorable to the growth of a large 

 number of cryptogams, from ferns down. Lichens I have never 

 collected at all, but they are fairly abundant in hammocks and 

 some other places.
