Hab. Canada. Mrs. Percival. Between Cumberland House and Bear Lake. Dr. Riclmrdson. New- 

 foundland. Dr, Morrison, Straits of De Fuca and Observatory Inlet, on the North-West Coast. Dr, 

 Scouler. — This plant varies in the pubescence of its leaves, and in the presence or absence of the mucro. 

 Even in maritime specimens I do not find the seeds margined as in our A. marina. In all, the root is 

 annual. — Schlechtendal and Chamisso mention it as an inhabitant of California, and, indeed, I have specimens 

 from almost every part of the world.

Catiles caespitosi, infeme decumbentes, ramosi, valde foliosi, dein erecti, parce foliosi, ut et tota planta, 

 glaberrima. JFoiia opposita, inferiora et in ramis sterilibus fasciculata, omnia angustissime lineari-setacea, 

 nitida, rigida, unciam ad 3 uncias longa, recta vei subcurvata, basi subdilatata atque connata, apice raucrone 

 curvato terminata, Hami fertiles vix spithamsei, apice 1-3-flori; pedicelli bracteati, Flores majusculi. 

 Ckil^cis sepala 5, ovata, obtusissima, margine diaphana, dorso inferne 5-nervia. Pet. obovata. Stam. 10. 

 Cktpsula late ovata, 3-valvis. 



Hab. Shores of the Arctic Sea. Dr. Richardson. — This belongs to a natural little groupe of Atcti- 

 arife, with very narrow and long leaves growing in fascicles on the short barren stems; most of them are 

 inhabitants of Asia, (and not the more northern parts,) or the countries of Europe bordering upon it. My 

 specimens of the A, nardifolia of Ledebour, from Dr. Fischer and Mr, Prescott, gathered by the former of 

 these Naturalists, exactly correspond with those of Dr. Richardson from lat. 70° of North America : and 

 these again approach so near to the A. lychnidea of Bieberstein, from the Iberian Caucasus, that, except 

 in the pubescence of the latter, there is scarcely any difference.
