lands is the proportionate breadth of the leaves, these being wider 

 in the plants from the higher altitudes. 



Phacelia hirsuta Nutt. Trans, Am. Phil. Soc. (II.) 5: 191. 



1833-37- 



Although classed as an annual, this Phacelia appears to be a 

 biennial. Mr. Nuttall, in the original description, says " annual or 

 perhaps also biennial." On Stone Mountain, Georgia, the species 

 flowers in the spring, the plants soon die and disappear on ac- 

 count of the extreme heat, the seeds falling to the ground at once 

 germinate, producing tufts of spatulate, oblong-spatulate or obo- 

 vate, short-petioled, sharply serrate leaves which are not in the 

 least pinnatifid, as are those of the following season. 



ViTEX Agnus-castus L. Sp. PL 637. 1753- 



This shrub is fast becoming naturalized in the Southern States. 

 Miss K. S. Taylor found it about Columbia, South Carolina, in 

 1 89 1, and I collected it in 1895 at both Darien and near Fort Har- 

 rington, in southeastern Georgia. 



Cestrum Parqui L'Her. Stirp. Nov. 73. 1783-84. 



We have no record of the occurrence of this species on our 

 eastern sea-board, but it is now doubtless established al many 

 places in the Southern States. In 1895 I found quantities in and 

 about Darien, Georgia. 



Leonotis nepetaefolia Ait. Hort. Kew. Ed. 2, 3 : 409. 181 1. 



Dr. Chapman reports this introduced plant from Georgia and 

 Florida. We now have excellent specimens collected by Prof. 

 Underwood at Auburn, Lee County, Alabama. 



Filago nivea. 



Evax midticaiilis DC. Prodr. 5: 459. 1836. Not Filagc 

 multicaidis Lam. 1778. 



This is one of the Compositae belonging west of the Missis- 

 sippi River that has been traveling gradually eastward ; in 1895 I 

 found it very plentiful about Stone Mountain, Georgia.
