Comparative Distribution 



Myrica cerifera L.^ grows in brackish marshes, in sandy soil on the 

 border of brackish ponds, estuaries and near the sea from as far north 

 as the Tuckahoe River, N. J., through Southern Jersey, Maryland, 

 Virginia, as far south as Southern Florida, west through the Gulf States 

 to the shores of Arkansas Bay in Texas and northward in the region west 

 of the Mississippi to the valley of he Washita River in Arkansas. Dr. 

 Macfarlane and myself collected it along the banks of the Tuckahoe 

 River, around the marshes and ponds bordering Petersburg road, at 

 Palermo, Rio Grande, Wildwood, Cape May and Ocean City, N. J. 



Myrica cerifera pumila (Michaux)^ is found in low, sandy Pine Barren 

 regions of South Carolina, Georgia and Florida, and on dry sand, and 

 hills in Northern Alabama, Eastern Texas, Northern Louisaina and 

 Southern Arkansas. 



Myrica Carolinensis (Miller)^ thrives in sandy, or sterile soil chiefly 

 near the coast, but also in inland swamps and pine forests, from Labrador 

 to Florida and Louisiana, on the border of the Great Lakes and in Indiana. 

 We collected it at Noroton, Connecticut and at Tuckahoe, Clementon, 

 Albion, Palermo, Ocean City, Rio Grande, Wildwood, Wildwood Junc- 

 tion, and Petersburg in N. J. 



Myrica Macfarlanei (Youngken) {M. cerifera x M. Carolinensis) 

 grows in the sandly soil of swamps, and on pine and holly forests near 

 the sea in Southern New Jersey. W^e have found it at Palermo, Rio 

 Grande, Wildwood, Tuckahoe, Cape May and Ocean City, wherever 

 both of its parents — M. cerifera L. and M. Carolinensis Miller — abound. 



Myrica Gale (L)^ is widely distributed through northern regions, from 

 Labrador and Newfoundland as far south as Warren County, New 

 Jersey, from the Atlantic to the Pacific, and in eastern mountain regions 

 to Virginia. 



It was collected in 1913 on the border of back waters occasionally 

 communicating with the sea at Peaks Island and Chebeague in Casco 

 Bay, Maine, and in 1899 on Martha's Vineyard, Massachusetts by Dr. 

 John M. Macfarlane. 



Myrica inodora (W. Bartram)^ is found in deep swamps in the vicinity 

 of Mobile and Stockton, Alabama, near Poplarville, Mississippi in the 

 valley of the Pearl River, and near Appalachicola, Florida.
