12 I. BANUNCULACEAE. [Ranunculus. 



Var. angustatus. Leaves narrow-oblong, lin.-ljin. long, Jin. broad, spreading, pinnae deeply 

 incised, rhaohis more hairy than in the type. Scapes very slender, hairy, spreading. Flowers small. 

 Otago : Maungatua, Petrie ! 



The typical form is easily recognised by its soft, finely-ont leaves, which sometimes have 

 capillary segments, and are always shorter than the scapes. Var. angiistatus should probably be 

 placed under the next species, with which it agrees in the narrow leaves and slender hairy scapes ; 

 but the carpels are unknown. Hooker, I.e., mentions a plant with less divided leaves and long hairs 

 on scape and petiole sent in a flowerless state from the Ruahine by Cclenso. 



15. R. gracilipes, Hook, f., Handbk. 8. Rootstock short, with rather 

 stout fibrous roots. Leaves all radical, glabrate or villous, lin.— 6in. long, 

 iin.— iin. broad; petioles slender; blade linear, oblong pinnate or twice pinnate. 

 Leaflets in from 2-7 pairs, sessile or petioled, nearly entire or lobed, or 3-fid or 

 3-partite or 2-ternate, the segments cuneate at the base, usually acute or 

 subacute at the tip. Scapes 1—5, 2in.— 7in. high, slender, naked, villous, 

 1-flowered. Sepals 5, narrow-ovate, hairy, spreading. Petals 5—10, narrow, 

 obovate, narrowed into a slender claw with a gland above the base. Stigma 

 short, slender, oblique. Receptacle conical. Achenes not seen.

In the Handbook this species is described as perfectly glabrous, but the fine series of specimens 

 in Mr. Petrie's herbarium, and those for which I am indebted to him, are pubescent or villous, rarely 

 glabrate, never glabrous, and the petals are never retuse. Occasionally the leaves are rather fleshy 

 and the rhachis is flattened. 



16. R. sericophyllus, Hook. /., Handbk. 6. The entire plant ex- 

 cessively silky, rarely glabrate. Rootstock short, stout. Leaves all radical, 

 lin.— 2in. long; petiole broadly sheathing; blade ovate or broadly ovate, 3-pin- 

 natisect ; segments very short, subacute or acute, tipped with a pencil of 

 silky hairs. Scape exceeding the leaves, stout, naked or with an entire or 

 divided bract, 1-flowered. Flowers liin. in diameter. Sepals 5, broadly oblong 

 or linear. Petals 5-10, obovate-cuneate, with naked glands. Receptacle ovoid. 

 Achenes forming a globose head, slightly turgid, faintly keeled, with a filiform 

 flexuous style as long as the achene.

 Dec, Jan. 



A singular plant, with golden-yellow flowers. Mr. Petrie's specimens are glabrate or almost 

 glabrous. 



17. R. Berggrenii, Petrie in Trans. N.Z.I, xix. (1886) 325. A stemless 

 species, glabrous in all its parts. Rootstock rather stout, rarely horizontal, 

 but not creeping, with thick vertical rootlets. Leaves all radical, on flattened 

 petioles iin.-lin. long ; blade iin.-fin. in diameter, orbicular or orbicular- 

 reniform, with an open sinus, unequally 3-partite to the middle ; segments lobed, 

 crenate. Scapes 1, rarely 2, naked, 1-flowered. Sepals 5, broadly ovate, 

 margins scarious. Petals 5, narrow-obovate, exceeding the sepals, gland near 

 the base ; style subulate, straight. Achenes not seen.
