R. Chamissonis, Sfhlecht. Aniraad. Eanunc. i. 12, t. 1, is known only ou the Asiatic side 

 of Bering Strait, and is much nearer the following, but with more utricular and gibbous fruit 

 and longer more naked style (according to herb. KewJ ; it is very little known. 



R. glaciAlis, L., of Europe, on the other hand, coming as near the American continent 

 as Greenland, has dark-hairy calyx and longer beaked broadly semi-ovate carpels ; when young 

 these are wholly scarious-utricular ; in age the portion immediately around tlie seed becomes 

 coriaceous, the rest forming tlie hyaline wing, which, however, is bilamellar and pervious. 



§ 4. Cyrtorhyncha,^ Gray. Petals pale yellow, bearing a prominent simple 

 or bifid callosity on the inner face (with the whitish or yellowish membranaceous 

 sepals) deciduous : stamens about 20 : carpels in a globular head, Thalictrnin- 

 like, in fruit somewhat utricular akenes, oblong, terete, or ovate and laterally 

 flattened, prominently about 10-costate, tipped with a short subulate inflexed or 

 slightly recurved style, subcoriaceous, loosely filled by the oblong erect seed : 

 fibrose-rooted perennials. — (Benth. & Hook. Gen. i. 6.) Proc. Acad. Philad.

 and parted into oblong or lanceolate lobes ; radical loug-petioled, cauline one or two and 

 small : stems corymbosely several-flowered : petals 5 to 9, 2 lines long, spatulate-oblong : 

 akenes a line or so long. — C urtorhyncha ranunculina, Nutt. in Torr. & Gray, 1. c. — Rocky

R. Cooleyae, Vasey & Rose. Glabrous, 3 to 10 inches high : root a cluster of stout fibres : 

 leaves chiefly radical, orbicular in outline, deeply and palmately 3-5-cleft, 1 to 1^ inches 

 in diameter ; the lobes flabelliform, crenate-dentate and again more or less deeply parted ; 

 the cauline leaves solitary or absent, smaller and of simpler contour : stem simple or once 

 branched : sepals greenish or yellowish white, broadly oblong, obtuse, 4 lines in length : 

 petals bright yellow, having a bifid thickening near the junction of the very short claw and 

 the narrowly oblong blade, 2^ to 3 lines in length : carpels very numerous, only partly 

 ripening, at maturity ovate, laterally compressed and keeled, tipped with a slender gently 

 recurved style with small terminal stigma. — Contrib. U. S. Nat. Herb. i. 289, t. 22.

 Alaska, near Juneau, Miss Cooley ; St Elias Alps above Disenchantment Bay, Fiinston ; fl. &

 petals of the preceding. 



§ 5. Halodes, Gray. Petals yellow, with nectariferous spot and scale,
