12 RANUNCULACEZ. (Ranunculus. 
Var. b, sericeus, Kirk, Students’ Fl. 9.—Achenes clothed with silky 
hairs. 
Var. c, dentatus, Kirk, l.c. 9.—Leaves broadly ovate to ovate-lanceolate, 
coarsely toothed or dentate, clothed on both surfaces with strigose ferruginous. 
pubescence, sometimes almost shaggy. 
Norru Istanp: Tararua Mountains, Buchanan! Sours Isuanp: Wairau 
Gorge and Tarndale, Sinclair, T. F. C.; Spenser Mountains, Kaikoura Moun- 
tains, Kirk ! Marlborough, Monro; Clarence Valley, 7’. F'. C.; Mount Torlesse 
and Upper Waimakariri, Kirk! Cockayne! Var. b: Kaikoura Mountains, 
Kirk! Var.c: Not uncommon in mountain districts in Marlborough and 
Canterbury, from the Clarence River southwards. 1500-4500 ft. December 
—January. 
A very variable plant, united with R. pingwis by Hooker, but differing from 
that species in the petals being always much longer than the sepals, in the scape 
being usually branched and not thickened upwards, and in the longer styles to 
the achenes. The var. dentatus has a very different appearance to the typical 
form, and but for the occurrence of numerous intermediates might have been 
treated as a distinct species. 
6. R. pinguis, Hook. f. Fl. Antarct. i. 3, t. 1.—Short, stout, 
usually rather fleshy, 2-10 in. high, sparingly pilose or almost gla- 
brous. Rootstock stout, with numerous fleshy rootlets. Leaves all 
radical, on long stout petioles with stout sheathing bases; blade 
1-3 in. diam., reniform, deeply crenate-lobed. Scape as long or 
Jonger than the leaves, stout, thickened upwards, naked or with 1-2 
bracts above the middie, 1-flowered. Flower lin. diam., yellow. 
Sepals 5-6, oblong. Petals 5-8, obovate or linear-oblong, hardly 
as long as the sepals, with 1-3 glandular pits towards the base. 
Receptacle broadly oblong. Achenes very numerous, small, gla- 
brous ; style short, straight, with 3 narrow wings at the base.—

Fil. 5. 
AUCKLAND AND CAMPBELL IsLANDS: Not uncommon, ascending to nearly 
2000 ft., Hooker, Filhol! Kirk! 
Sir J. D. Hooker distinguishes two varieties in the Flora Antarctica, one 
(var. pilosus) being much more hairy than the type, with linear petals always 
furnished with 3 glandular pits; the other (var. rhombifolius) smaller, with the 
leaves rhomboid-cuneate and 3-5-fid. 
7. R. nivicola, Hook. Ic. Plant. t. 571, 572.—Krect, usually 
rather slender, paniculately branched above, 2-3 ft. high, more or 
less- covered with long soft white spreading hairs or nearly gla- 
brous. Rootstock short. stout. Radical leaves on long petioles 
4-12 in. long with broad sheathing bases; blade 3-6in. diam. or 
even more, cordate-reniform, more or less deeply 3-7-lobed, lobes 
broadly cuneate, inciso-crenate. Cauline leaves deeply cut and 
lobed, upper laciniate. Flowers many, large, golden-yellow, 
1-14in. diam. Sepals 5, linear-oblong, pilose. Petals usually 
numerous, 8-15, narrow cuneate-obovate, emarginate, each with 
a single glandular pit near the base. Achenes forming a small 
rounded head, glabrous, turgid ; style straight, hooked at the tip.—-
