 RANUNCULACE^E. 



1. Ranunculus aquatilis, var. arcticus. Foliis omnibus emersis, consimilibus, 

 profunde tripartitis ; partitionibus cuneatis, ad marginem dilatatis, crenatis ; flore albo ; 

 sepalis ovalibus, concavis, petala fere aequantibus. 



This form, of which I have only two specimens, has a great affinity with De Can- 

 dolle's R. aquatilis, var. hederaceus, R. hederaceus, Lam., not of Linn, (vide Fl. Franc, 

 vol. 4, p. 894.) The stems are fistulous repent, with small fascicles of radical fibres at 

 each node below the scape. No capillaceo-multifid leaves ; they are all suborbicular 

 tripartite, on long vaginant petioles, 3—4 at the base of each peduncle ; leaflets cu- 

 neate, with dilated crenate margins, each crenature having a blunt mucro. Scape 

 thick, naked, one-flowered, 3 — 3£ inches high. Flower white, middle size, with five 

 oval and concave sepals about the length of the petals. 



Disko and adjacent coast, 70°. 



2. R. glacialis, Linn., sp. plant, p. 777. D. C. Prodr. 1, p. 30. Torr. and Gr. 1, 

 p. 16. 



North Proven, 72°. 



3. R. nivalis, Linn., Fl. Lapp., p. 158— T. 8. D. C. Prodr. 1, p. 35. Hook, Fl. 

 Bor. Am. 1, p. 17. Torr. and Gr. 1, p. 20. 



a. R. nivalis Linn. Leaves glabrous, on long ciliate petioles, somewhat reniform, 

 crenato-lobate, lobes obtuse, more or less deep, equal or narrower at base, with con- 

 spicuous divergent veins. Cauline leaves sessile, palmate. Flowers rather large, deep 

 yellow ; petals oval-rounded, about twice the length of the calyx which, as well as 

 the peduncle, is covered with a thick, brown toment. Root perpendicular, with nu- 

 merous white and thick fibres, indicating a plant deeply rooted in mossy beds. 



Stations of Smith's Sound, 78°— 80°. 



/?. R. Br., in Parry's first voy. app., p. 264, R. nivalis, var. Vahl., Fl. Lapp, p. 157. 

 R. sulphureus, Soland. in Phipps' Voy., p. 202. Leaves cuneate, palmately lobed, 

 lobes generally narrower at base. Flower pale yellow. 



Smith's Sound Stations, 78°— 80°. 



4 I have two very damaged specimens, closely allied, by the leaves, 



with the preceding variety, but widely different on other points, and which might be 

 R. sabinii, R. Br., collected on the shores of Melville Island in Parry's first voyage. 

 The radical leaves are cuneate, veined, ciliate, deeply 3-parted, with lateral partitions 

 bifid, supported on long vaginant membranaceous petioles. Stem apparently two- 

 flowered. Flowers pale yellow, smaller than the preceding. Sepals and peduncles
