 Inflorescence interrupted, at least the lower clusters somewhat remote; pedicels 

 several to an axil, up to 10 mm long; leaves slightly decurrent on the stem; 



corollas 25-40 mm wide 2. V. phlomoides. 



Inflorescence densely crowded; pedicels usually 1 to an axil, very short or lacking;

1. Verbascum Blattaria L. Moth Mullein. Map 1809. Infrequent 

 to frequent or locally common throughout the state. It is spreading every 

 year. It is found mostly in pastures, fallow ground, and hayfields and 

 along roadsides. There are two forms, a yellow-flowered one, the typical 

 form, and a white-flowered one (f. albiflora (G. Don) House). Since my 

 labels do not always give the color of the flower, unfortunately, I am not 

 able to give their ratio of abundance. My recollection is, however, that the 

 yellow form is much more common. Through neglect we permitted the 

 white form to become established in our three-acre arboretum about 10 

 years ago. Since then I have endeavored to exterminate it by digging every 

 plant as soon as discovered, and not a single plant has been permitted to 

 seed. The viability of the seed is shown, however, by the fact that a few 

 plants were found last year. It might be added that I have never seen a 

 yellow-flowered plant in the tract. I have seen large areas of this species 

 and I do not recall that I ever saw the two forms growing together, al- 

 though this is quite possible. 



Nat. of Eu. ; naturalized throughout the U. S. 



2. Verbascum phlomoides L. Map 1810. About 1925 Mr. Walter Neff 

 and Mrs. Ivy Neff discovered this species as a common weed in the Cedar- 

 ville Cemetery and nearby pastures and roadside in Carroll County, about 

 two or two and a half miles southwest of Burnettsville. Mrs. Neff has 

 written of the discovery and described the plant (Amer. Bot. 36: 85-87. 

 1930) . At that time the name was still in controversy. I visited this colony 

 in 1929 and found that it formed an almost complete stand in a pasture of 

 two to three acres and that it was scattered in pasture fields for a distance
