some of the high mountains of Europe. I have no opportu-

P. foliis elliptico-lanceolatis integerrimis glabris, scapo 1- 



floro, corollae laciniis ovatis integerrimis. 



Root long, thick, imbricated with the vestiges of leaves. 

 Leaves elliptico-lanceolate or oblong, sometimes spathulate, 

 petiolate, about an inch long, obtuse, membranaceous,

P. caule simplici monostachyo, foliis linearibus glabris 

 margine revolutis, spica brevi-ovata crassa, bracteis ovatis
