to Florida and Louisiana. (But apparently not yet known in Vir- 
ginia and the Carolinas.) 
Myrica. All the American representatives of this genus seem to 
be confined to the glacial region and coastal plain (except that Dr. 
Mohr has reported M. pumila from one station in upper Alabama). 
One species, M. Caro/inensis, Mill. (until recently confused with the 
more southern M, cerifera, L.), is common to both regions, but with a 
striking diversity of habitat. In central Massachusetts it grows 
principally in rocky pastures, in Virginia on the dunes along the 
coast, and in Georgia usually on sandy margins of swamps. 
Sarracenia purpurea, L. West to Minnesota and British Columbia 
(?), south to Florida and West Tennessee. The other six species 
of the genus are confined to the coastal plain, except that two or 
three of them occur locally in Western North Carolina and the 
mountains of Alabama (possibly also in upper Georgia). 
Drosera filiformis, Raf. South to Florida and Mississippi, but not 
extending very far from the coast. This genus seems to be almost 
wanting in the Piedmont region and southern mountains. 
Rosa Carolina, L. West to Minnesota, south to Florida, Arkansas 
and Louisiana. (Not reported from Alabama.) 
Aronia arbutifolia (L.) Ell. West to the Dakotas and Nebraska, 
south to Florida, Arkansas and Louisiana. Also in the mountains of 
Tennessee (Gattinger) and rarely in Middle Georgia. 
Polygala cruciata, L. West to Minnesota and Kansas (?), south 
to Florida and Louisiana. Also in East Tennessee (Gattinger) and 
western Middle Georgia.! 
Mex glabra (L.) Gray. Almost confined to the coastal plain. 
South to Florida and Louisiana. Also in Carroll County, Middle 
Georgia (C. Z. Boynton) ? 
Viola lanceolata, L. West to Minnesota, south to Georgia and 
Texas. Also in the mountains of Tennessee (Gattinger). 
Decodon verticillatus (L.) Ell. West to Minnesota (?), south to 
Florida and Louisiana. Also rarely in Northwest Georgia (2. Wilson) 
and Tennessee (Gattinger), but probably not found in the Blue 
Ridge and Piedmont region. 
Rhexia Virginica, L. West to Indiana and Kansas, south to Flor-
