typical form, were found at Paine Creek. The pubescence of the stem and the 

 ovaries may be crisp, as in T. perfoliatum, or villous, and the sepals may be narrow 

 or broad, obtuse or acute. 



la. T. perfoliatum L., var. glaucescens Wiegand. (See Rhodora 20: 116. 1918. 

 T. aurantiacum, var. glaucescens Wiegand.) 



In situations similar to the preceding ; frequent. June. 



Equally common with var. aurantiacum, and of the same distribution: Lick 

 Brook; South Hill; Six Mile Creek; Fall Creek, above Forest Home; Renwick slope; 

 Esty; in shaly talus, Ludlowville; bottom land, Paine Creek glen (type locality). 



Cent. N. Y. and Pa. 



A colony in Paine Creek glen, and another along the state road at Esty, had 

 some plants with strongly perfoliate leaves but others with the leaves separate. The 

 var. glaucescens resembles the acute-sepaled types of var. aurantiacum more closely 

 than it does the typical form of the species.
