Melampyrum lineare latifolium (Muhl.) Beauverd in Mem. 



Soc. Phys. Geneve 38: 474. 1916. 

 Melampyrum lineare americanum (Michx.) Beauverd, I.e. 

 476. 1916. Beauverd distinguishes latifolium with bracts 

 broader, the lower entire, the upper entire or few- toothed, 

 and the first flower placed at the third or fourth node, 

 from americanum with bracts narrower, the lower entire 

 or slightly toothed, the upper always toothed, and the 

 first flower in the axil of the fourth to eighth node. His 

 americanum is transitional from latifolium to lineare 

 itself, from which he distinguishes both these varieties as 

 having corolla whitish, tinged with purple, instead of 

 pale-yellow, tinged with purple. The corolla of the 

 species, as well of var. latifolium as I understand it, has the 

 corolla white, posteriorly more or less tinged with red, 

 especially in age, and only the palate yellow. His color 

 distinction cannot be maintained, and I should consider 

 the broadest, most entire-leaved plants as an extreme of 

 this variety. 

 Flowering from late May to mid-August, and soon ripening 

 fruit. 



Dry open woods, in potassic soil, sandy or sterile, locally 

 common on sandstone or shale ridges, etc., throughout the area 

 above the Fall-line; in the Coastal Plain occasional on Long 

 Island and in the Middle District of southern New Jersey. 

 Intergrading to the species. 



Local Specimens of the Author's Collecting 

 As my own collections illustrating our local species of Scro- 

 phulariaceae in part have already been, and in part are soon to 

 be, distributed to various herbaria, it may be well here to present 

 a summary of the numbers of these. The specimen numbers 

 will be grouped by species and states. All are from the local 

 flora as defined in the introduction to these studies.

 Agalinis Holmiana (N. Y.) 10167. (N. J.) 1662, 2695, 3544,
