 and from the Columbia to Unalaschka. T>r Scouler, Tolmie. Ckamisso. Bongard. — ^. Newfoundland. Miss 

 Brenton, — The remote but large and strong teeth in ourvar. bring the state of the plant near P. Coronopus, 

 of which it may be a var, 



6. P. pauciflora (Ph. Am. 1. p, 99) ; foliis lineari-lanceolatis integerrimis glabriusculisj 

 scapo tereti foliis breviore, spica pauciflora interrupta, bracteis ovatis acutis glabris. 

 P. elongata. Ph. SuppL 11. p. 729 (according to Nutt.). 



Hab, Labrador (Ph.) ; — but I have great doubts about this plant. The original P, elongata, gathered by 

 Bradbruy in Upper Louisiana, which Nuttall pronounces to be the same with P. pauciflora, is identical with 

 pusilla, which I have never seen from British N. America, and I should think is a very unlikely inhabitant 

 of Labrador. 



7. P. gnaphalioides (Nutt. Gen. Am, I. p. 100); totalonge sericeo-villosa, foliis lineari- 

 Janceolatis acutissimis, spica elongata cylindrica densiflora, staminibus inclusis, capsula 

 biloculari disperma. — P. Lagopus. Ph. [nonLinn.) — 13. bracteis longissimis spinulosis. — P. 

 aristala. Mx.

Hab. N. W. America. Menzies (in Herb, nostr.). Common on the barren plains of the Columbia. 

 Dovglas. — The Columbia is probably the northern limit of this fine species. It is an inhabitant of the 

 Southern United States. Mr Nuttall gathered it in Arkansa ; MrDrumraond at San Felipe in Texas (Coll. 

 IIL n. 354} ; and the var. aristata in the same place (Coll. III. n. 353). Mr Nuttall has proved that the 

 P. aristata is only an accidental var. of his P. gnaphalioides.

Hab. About Carlton House Fort on the Saskatchawan. Dn/mTwowc?.— Bradbury (from whom there is 

 an authentic specimen in my herbarium) discovered this plant in Upper Louisiana. The present inhabits a 

 much more northern station, the most northerly perhaps of any of the genus ; of which the species are more 

 frequent in the south.
