2. Fedicularis canadensis L. 



Pedicidaris canadensis L., Mant. 86. 1767. "Habitat in America septen- 

 trionali. Kalni." 



Woodland or knolls in meadows, throughout above the Fall- 

 line, probably more common northward; in the Coastal Plain 

 descending locally to northern Florida. Ranges from Nova Scotia 

 to Manitoba, south to Florida and Texas. 



Pennell (Alabama)— 9722. (Tennessee)— 9789. 



38. MELAMPYRUM Linne. 

 Melampyrum L., Sp. PI. 605. 1753. 

 Type species, M. cristatum L.,.of Europe. 



Main stem-leaves linear or lanceolate-linear. Bracts conspicuously 

 fimbriate near base, with teeth frequently as long as the width 

 of the blade. Capsules mostly 6-7 mm. long, curved and usu- 

 ally attenuate-beaked. Seeds 2-2.5 mm, long, brown to black- 

 ish 1. M. lineare. 



Main stem-leaves linear-lanceolate to nearly ovate. Bracts slightly 

 or not fimbriate near base, the teeth shorter than the width of 

 the blades. Capsules frequently larger, reaching 8-9 mm. long, 

 slightly or not curved, and less or not attenuate-beaked. Seeds 

 often larger, reaching 3 mm. long, usually black. 



la. M. lineare lati folium. 



1. Melampyrum lineare Desr. 



Melampyrum lineare Desr., Lam., Encyc. 4: 22. 1796. "Rapportee de 

 la Caroline par M. Fraser ... (v. s.)." Description made from 

 a very young plant, but certainly of the form here considered. Char- 

 acterization of the calyx as 5-toothed certainly erroneous. 



Open woodland, thin acid soil, upland and probably midland 

 districts of North Carolina. In the Appalachians mainly replaced 

 by var. lalifolium. Ranges northward to Long Island, and through 

 its varieties much further northward and across the continent. 



Flowering and fruiting through the summer. Corolla white, 



more or less pinkish externally, the palate yellow. 



la. Melampyrum lineare latifolium (Miihl.) Beauverd. 



Melampyrum americanum Michx., Fl. Bor. Amer. 2: 16. 1803. "Hab. a 



sinu Hudsonis ad montosam Carolinam." (A. Michaux.) Description 



evidently of the prevalent inland broader-leaved plant. 

 Melampyrum latifolium Muhl. (Cat. 57. nomen nudum); Eaton, Bot. 316. 



1818. From Muhlenberg's Catalog, the type station is in Delaware. 



Type not seen, but evidently is the prevalent inland plant. 

 Melampyrum lineare latifolium (Muhl.) Beauverd, Mem. Soc. Phys. Geneve 



38: 474. 1916. 



Moist open woodland, in the Appalachians south to northern 

 Georgia. The prevalent inland plant, southward attaining its great- 

 est distinctness from the species.
