RANUNCULACEiE. [Ranuncuhs: 



to our last mentioned yar. which is only 3 or 4 inches in length, with an ahnost orbicular circumscription 

 to the leaves, having all multifid and linear segments and small solitary flowers, and which seems to be 

 exactly the H. Langsdorffii^ of De CandoUe. Intermediate states possess the natant broad foliage, similar 

 to what is so common on the R. aquatilts. Sometimes there is a little pubescence on the stem and leaves. 

 Richardson has well described my varieties y. and S, and particularly noticed the remarkable character of 

 the style. Mr. Brown's R. inundatus, from New Holland, appears to be allied to this.

 Whale Islands in the Arctic Sea, LieuL Ross, — A rare plant; being very alpine or very arctic. The lower 

 part of the stem is filiform, and creeps much under ground, throwing out long, white, fibrous radicles. 

 The scape is sometimes furnished with a single leaf, and this is remarkably the case with the specimens 

 from the coast; and it is so figured by Reichenbach. The calyx consists of 3 sepals, and the corolla of 6 

 (Schlechtendal says 8) spathulate petals; hence it is allied to the genus Ficaria, and, like it, it bears gemmse 

 or little bulbs. Heads roundish, of few carpels, which are margined. Styles as long as the capsules, flattened 

 at the base, and recurved, 



15. R. hyperhoreus ; foliis glabris petiolatis trifidis lobis ovali-oblongis divaricatis, 

 lateralibus subbifidis, medio iiitcgro, vaglnis basi biauriculatis, caule filiformi repente.

Hab. Marshes in the Rocky Mountains; lat. 52° to 57*'. Drummond. Arctic Islands. Capt. Sir F, 

 Parry. Edwards. Bay of Eschscholtz, and of Schischmaref. Chamisso, — Whole plant quite glabrous in the 

 American specimens, hairy in those of Sweden, which I have received from the late Professor C. Smith. 

 Stems creeping. Heads of gennens globose, compact. Each cariopsis or carpel is distinctly margined on the 

 back, and tipped with a y^ry short inconspicuous mucro.

• Whilst writing this paragraph, I had the pleasure to receive a letter from Mr. Arnott, dated St. Petersburgh, 

 who assures me, that on referring to Gmelin's Herbarium, in the Museum of the Academy of that city, he finds the 

 plant ivhich corresponds with Tab. 83. B. of the " Flora Sibirica " to be truly our R. Purshii, and, he believes, cer- 

 tainly the Langsdorffii of De CandoIIe. It is equally the It. Gmelini of De Candolle, whose only authority is the 

 figure of Gmelin, which he cites. But it is not the R. Gmelini oi Schlechtendal's Animadv. p. 33, for which he 

 refers to Gmel t. 83. b, f. c. (though, from a misprint, it is made 836,) not 83. B. That plant again, {Gmd. 83. 6. 

 / c.) Mr. Arnott assures me, is n. hi/perboreus j and Eschscholtz's plant, likewise quoted, which I possess in my 

 Herbarium, is the same species, htjperhoreus. R. Gmelini, therefore, no longer exists as a species.
