112 Harper: Observations on Taxodium 



which ordinarily grows only in the swamps and bayous of the low 

 subcoastal regions, attains an eaormous size at the edge of the 

 deeper holes near the heads of permanent water of the Pedernales 

 . and other streams. These localities are at altitudes from 

 1,000 to 1,750 feet above the sea, hundreds of miles west of the 

 great cypress swamps of the eastern tier of Texan counties, with 

 which they have no possible continuity." (See also Bray, U. S. 

 Dept. Agric, Bureau of Forestry Bull. 47 : 53 ; 49 : 16. 1904.) 



TaXODIUM IMBRICARIUM 



This species is very abundant in the coastal plain of Georgia, 

 where I have seen it in every county in which Oligocene or later 

 rocks occur, /. €., from the inland edge of the pine-barrens to 

 Florida and the coast. On the way to Georgia in 1903 I saw it 

 in Moore County, N. C, near the fall-line,* and in Hampton 

 County, S. C. It is common in Nassau and Baker Counties in 

 Florida, but no data are yet available as to its southern limit in 



that state. 



Outside of the pine-barrens in Georgia there are several out- 

 lying stations for it, where it grows in shallow ponds. These have 

 been noted as follows : In Richmond County between Adam and 

 Adventure, in Jefferson near Wadley, in Washington near Sanders- 

 ville, in Taylor near "Reynolds, and in Terrell between Bronwood 

 and Dawson. All these localities, according to the best informar 

 tion at present obtainable, seem to be underlaid by rocks of the 

 Claibornian division of the Eocene. The Taylor County station 

 is of interest as being the farthest inland, and most remote from 

 the pine-barrens. At this point the Taxoditan is in imminent dan- 

 ger of extinction, most of the trees having been already cut and 

 used up (it being apparently the only cypress pond known In the 

 vicinity), and few if any young trees were seen. The principal 

 vegetation of this pond is Liqjddamhar^ with a few Crataegus 

 aestivalis bushes. 



Toward the coast Taxodimn inihicaritim extends nearly to 

 Brunswick, within two or three miles of salt water and not over 

 ten miles from the open ocean. There its habitat and associates 

 are much the same as they are fifty or a hundred miles inland.
