 ^ ■ P. Unalasdiensis is common from south- 



ern Alaska and Alberta to California and Colorado, and grows in 

 damp woods. 



Type: '' Ins. Aleut." 



The following locality is remarkable, being far out of the sup- 

 posed range : 



Quebec: Jupiter River, Anticosti, i^d>2), John Macoiin.

Tall and strict, 3-10 dm. high, leafy below : basal leaves ob-

 upper reduced and bract-like, lanceolate, 

 1-2 cm. long : spike strict and lax, 1-3

I have not seen the type, collected by Cooper at San Diego, 

 California, but the plants cited below agree with the description 

 and were collected in the same region. It is from these I have 

 drawn the description and figure. 



Type: "On Clay hills near San Diego, California; Dr. J. G. 

 Cooper."
