f. Walpolei Farwell) or brown purple (f. Billingtonii Farwell!) petals, 
filaments, and stigmas at Ypsilanti, Michigan. 
T. cernuum L. Sp. Pl. 339 (1753).—Low and mucky woodlands 
and copses chiefly in sandy noncalcareous regions along the coast: 
Newfoundland to eastern Pennsylvania and Delaware (West Virginia, 
Millspaugh; Georgia, Small, Britton). It extends inland to Coós 
County, New Hampshire, and Worcester County, Massachusetts, and 
is found locally on the sand plains about Albany, New York. A 
specimen collected by Macoun at Belleville, Ontario, is apparently 
the typical form though out of range. 
Var. macranthum var. nov. Petalis ovato-oblongis ovalibus vel 
plerumque obovatis 10-17 mm. latis; antheris maturitate 4.5-6.5 
mm. longis; pedunculis 12-40 mm. longis.—Flowers more showy 
than in the typical form with broader often obovate petals, larger 
anthers, longer peduncles and apparently somewhat larger fruit. 
The peduncles are generally straighter and more often deflexed than 
recurved, though this is not so marked toward the eastern portion 
of the range. At the local station the flowers as they grow older 
increase in size until the petals may reach a maximum width of 21 mm. 
and a length of 32 mm. The accrescence of the corolla is not so 
marked in the typical form. This variety inhabits alluvial or mucky 
soils chiefly in calcareous regions: Vermont, western Massachusetts 
and southeastern Pennsylvania to Minnesota, Saskatchewan and 
Mackenzie, chiefly in the vicinity of the Great Lakes. Specimens
