base, obtuse, apiculate or acute at the decurved apex (on ultimate 

 branches sometime acuminate); lobule separated from the stem by 

 about half its width, subparallel with the stem, short-clavate, con- 

 tracted toward base ; stylus a small disc-like or strongly crispate 

 process: underleaves distant, orbicular, strongly reflexed at apex and 

 usually on the sides, bifid about one-sixth with a broad, shallow sinus 

 and obtuse or apiculate lobes, crispate-auriculate at base : leaf -cells 

 of lobe thick-walled, trigones and intermediate thickenings becoming 

 more pronounced on passing inward and toward the base ; discolored 

 cells usually indistinct, either scattered or in a short median line : 

 $ terminal on a short branch ; bracts in three or four pairs unequally 

 bifid, the lobe ovate, acute, irregularly dentate or crenate, especially 

 in the upper part, lobule lanceolate, acuminate, revolute on the mar- 

 gins, bearing at the base on the inner side a cluster of fine cilia, 

 otherwise subentire : bracteole free from the bracts, deeply bifid 

 with ovate-lanceolate, acute, irregularly dentate or laciniate lobes 

 and narrow sinus, margins ciliate at base, perianth exserted one-third 

 or more, oblong, narrowed into a short beak, postically strongly one- 

 keeled, smooth : $ spike oval, borne on a short lateral branch, bracts 

 in several pairs.

On rock and trees; Miquelon Island (Delamare): Newfoundland 

 (Waghorne) : Blackstone, Rhode Island (Bennett). " Vancouver and 

 Orcas Islands, Lyall. Collected also on the N. W. coast by Menzies 

 and Douglas.'''' ' Apparently rare, but probably more abundant in 

 the far north. 



In the absence of fertile American material the above descriptions 

 of involucre and perianth are drawn from Swedish plants collected 

 by Dr. Arnell. The Rhode Island specimens which I have had an 

 opportunity of examining are very fragmentary, but are apparently 

 referable to this species. 



1 Mitten, Jour. Liun. Soc , viii : 53. 1865. It is probable that these specimens from 

 the Pacific Coast would now be referred to other species.
