14 RANUNCULACES. [ Ranunculus. 
“« 
stout, straight or curved.—Students’ Fi. 158. RB. tenuis, Buch. in 
Trans. N.Z. Inst. xx. (1888) 255, t. 12. 
Sour Isntanp: Canterbury—Not uncommon on the mountains of the 
Middle Waimakariri from Mount Torlesse to Bealey, Hnys! Kirk! Petrie! 
Cockayne! T. F. C. Otago-—Lake Harris, Kirk; Hast Taieri, Buchanan ! 
2000-4000 ft. December-February. 
A well-marked species, apparently not closely allied to any other. Mr. 
Buchanan’s RF. tenuis differs from the type in the leaves being more pinnately 
divided, but is clearly the same species. I have a specimen with finely cut, 
almost decompound leaves, collected by Mr. Cockayne on the Candlestick 
Mountains, Canterbury. 
10. R. tenuicaulis, Cheesem. in Trans. N.Z. Inst. xvii. (1885) 
235.—Very slender, erect, sparingly pilose or nearly glabrous, 
4-18 in. high. Rootstock slender, with numerous fleshy rootlets. 
Leaves all radical, on slender petioles 2-6 in. long; blade 4-14 in. 
diam., about reniform in outline, cut to the base into 3, rarely 
5, broadly cuneate divisions, which are deeply and irregularly 
2-3-lobed; lobes narrow, often again toothed. Scape very slen- 
der, grooved, 1-flowered, usually with 2-3 simple or variously 
cut or lobed bracts about the middle. Petals 5, linear, acute. 
Achenes 5-20, loosely packed, spreading, shortly stipitate, fusi- 
form, gradually narrowed into a long spirally recurved style.— 
Kirk, Students’ Fi. 14. 
SourH Is~LanD: Canterbury — Mountains above Arthur’s Pass, T. F. C.; 
Craigieburn Mountains, Cockayne! Otago—Swampy Hill, Lee Stream, Mount 
Kyeburn, Clinton Saddle, Petrie ! 
A very curious species, remarkable for the fusiform achenes and long 
spirally recurved style. 
11. R. Haastii, Hook. f. Handb. N.Z. Fl. 6.—A very remark- 
able stout fleshy or coriaceous glaucous plant, 2—6in. high, 
glabrous except the leaf-sheaths, which are usually villous with 
long hairs. Rootstock stout and fleshy, often 6in. long and as 
thick as the thumb, viscid and milky when bruised, horizontal, 
giving off numerous long and stout rootlets as thick as whipcord. 
Radical leaves 1 or 2; petioles stout, fleshy, tapermg downwards, 
2-6 in. long; blade 2-4in. diam., broadly reniform or orbicular in 
outline, palmately cut to the base into 5-7 deeply and irregularly 
incised and lobed segments. Scape very thick and fleshy, grooved 
when dry, naked below, furnished above with 1-3 sessile cauline 
leaves which are deeply cut into linear lobes, forming a leafy 
involucre to the flowers. Peduncles 1-3, barely exceeding the 
cauline leaves, 1-flowered. Flowers 1-ldin. diam., yellow. 
Sepals 5, oblong, glabrous or neariy so. Petals 8-15, narrow- 
cuneate; gland single, basilar. Receptacle swollen, papillose. 
Achenes forming a rounded head #in. diam., glabrous, turgid ; 
style flattened, pointed, very broad at the base, the margins con- 
tinued down the front and back of the achene as wings.—Kzirk, 
Students’ Fl. 10.
