Ranunculus.] I. eanunculacbae. 11 



long, suborbicular, 3-5-lobed or 3-partite to the base ; segments often petiolulate, 

 obovate or obovate-spathulate, crenate or crenate-dentate ; pitted on the upper 

 surface when dry. Sheath of petiole short, broad, scarious. Scape usually- 

 solitary, shorter than the petiole, naked, 1-fiovvered. Sepals 5, narrow-elliptic. 

 Petals 5, twice as long as the sepals. Receptacle small, globose. Achenes 

 turgid, with a flexuous slender style equalling or exceeding the achene.

The description in the Handbook apparently includes both this species and the next, while 

 the thick rhizomes belong only to B. Haastii. It varies greatly in the division of the leaves, which 

 completely hide both flowers and fruit. I have not seen Ganterbary specimens. 



12. R. paucifolius, n. s. Rootstock short, stout, with thick vertical 

 fibres 6in.— Sin. long. Whole plant glabrous. Leaves 1 or 3, radical, lin.— 2in. 

 long, spreading, petiolate, suborbicular, cuneate or almost reniform at base, 

 nearly entire or 3— 5-lobed or partite nearly to the middle ; segments overlapping, 

 minutely crenate or subserrate, not pitted above. Petiole with a broad sheath 

 for half its length. Scape solitary, stout, naked, 1-flowered, equalling the 

 petioles. Sepals 5, ovate-oblong, subacute, deflexed. Petals 5. Achenes few, 

 turgid, with a straight subulate beak. 



SOUTH Island : Amongst limestone gravel, Broken Eiver, Waimakariri, J. D. Enys ! Deo. 



Nearly related to B. chordorhizos, but easily distinguished by the leaves never exceeding 

 2 or 3, and being carried on longer sheathing spreading petioles, while the scape equals or exceeds 

 the petiole^!, so that the flower is fully exposed. Better material is wanted to allow of a good 

 diagnosis being drawn, as I have only seen a single flower. Haast's plant from the Macaulay 

 River and Mount Somers Range, doubtfully referred to B. chordorhizos, may be identical with this. 



13. R. crithmifolius, Hook. /., Handbk. 6. A small glabrous, fleshy, 

 glaucous species. Rootstock short, stout, horizontal, with thick fleshy fibres. 

 Leaves all radical, on recurved petioles lin.— 2in. long; blade iin.— lin. broad, 

 reniform in outline, biternately multifid ; segments short, linear, Yoin. long, 

 obtuse. Scape stout, fleshy, erect, shorter than the leaves, 1-flowered. 

 Flowers small. Sepals linear-oblong. Petals not seen. Achenes in a globose 

 head iin. in diameter, turgid, keeled ; style sharp, straight, subulate. 



SOUTH Island: On shingle-slips, Wairau Gorge. 6,000ft. Travers. 



A very singular plant, easily recognised by its glaucous fleshy habit, finely-divided leaves, and 

 short 1-flowered scapes. Only a solitary specimen observed. 



14. R. Sinclairii, Hook, f., Handbk. 6. Glabrous, or with few weak 



hairs on the petioles and scapes; 2in.— 6in. high. Rootstock prostrate or erect. 



Leaves all radical, lin.— lin. long, tufted, oblong or ovate-oblong, 2-pinnatisect or 



multifid; segments short, narrow-linear or slightly ovate, acute or subacute, 



primary in 3 or 4 pairs, opposite ; petioles slightly sheathing. Scapes slender, 



exceeding the leaves, 1-flowered. Sepals 5. Petals 5, twice as long as the sepals, 



with a deep gland. Receptacle small, conical. Achenes few, small, slightly 



turgid ; style very short, straight, subulate.
