1418. P. Andromedea, Nutt. 



Pine woods. This is a very local plant. Along the bank of the 

 Gatineau between Ironsides and Chelsea, upon a heavy clay 

 bank, beneath pines, it is very abundant. "With the exception 

 of a single plant found at Rockclifie by Mr. A. J. Forward, this 

 is the only locality so far discovered in this district. It is a 

 curious plant, consisting of a stout, pinkish- white, erect, clammy- 

 pubescent, fleshy stem about two feet in height, bearing at the 

 base lanceolate scales instead of leaves, and above nodding white 

 flowers like those of Andromeda, in a long bracted raceme. Root, 

 a mass of fleshy fibi-es. It is supposed to be a parasite on the 

 roots of pines.
