[D. PARVIFLORUM Nutt. DRAGON HEAD. 



Found in 1918 along the lighthouse road near the Ithaca garbage dumps. 

 E. Que. to the Yukon, southw. to n. and w. N. Y., Mich., Wis., N. Mex., and Ariz. ; 

 also adventive farther eastw.] 



7. Prunella L. 

 1. P. vulgaris L. (Brunella vulgaris of Cayuga Fl.) Heal-all. Self-heal. 



Rich loamy, often clayey, soil, in fields, on roadsides, or on the borders of swamps; 

 very common. July-Oct. 



Newf. to B. C, southw. to Fla., La., and Ariz., including the Atlantic Coastal 

 Plain. In part naturalized from Eu. 



Corollas occasionally white or pink, sometimes very small or very short. Fernald 

 (Rhodora 15:179, 1913) has distinguished several varieties and forms, of which 

 the principal one in this region is var. lanceolata (Barton) Fernald. After much 

 study of local and other ma'terial, this variety is hot here retained. The broader and 

 shorter leaves are usually found where the habitat is more open and the growth more 

 stunted. The color of the calyx varies with soil and exposure, as is the case with 

 many plants.

 1. P. virginiana (L.) Benth. False Dragon Head.

 Ithaca, formerly (D.) ; at the former biological field station near the mouth of Fall 

 Creek; springy pasture one mile s. e. of Dry den; near Lake Como (G. B. & L. N. 

 Upton). 



Native from Que. to Minn., southw. to Fla., La., and Tex. ; rare or absent on the 

 Coastal Plain. 



Some authors adopt the name Dracocephalum (Tourn.) L. for this genus. Ben- 

 tham, who first segregated the genus Dracocephalum, placed the present species in 

 Physostegia.
