24 RANUNCULACES. (Ranunculus. 
Sourn Isnanp: Canterbury—Swamps in the Broken River basin, Hnys ! 
Kirk! T. F.C.; Tasman Valley, ‘’. F.C. Otago—Mount Cardrona, Petrie ! 
Altitudinal range from 2000 to 5000 ft. 
1 am indebted to Mr. Enys for an instructive series of specimens, all col- 
lected in one locality, showing passage-forms of leaves, from trilobate with entire 
lobes to trifoliolate with almost miultifid leaflets. In Mr. Petrie’s Mount 
Cardrona plant the leaves are trilobate, with the lobes entire or toothed, and the 
habit is somewhat different; but it is in young flower only, and more advanced 
specimens are required to prove its exact position with respect to the typical 
state. 
31. R. pachyrrhizus, Hook. f. Handb. N.Z. Fil. 8.—Small, 
stout, much depressed, iorming dense patches seldom more than 
14in. high, more or less clothed with long soft hairs. Rootstock 
stout, fleshy, creeping, branched; rootlets thick and stringy. 
Leaves crowded at the ends of the divisions of the rootstock, all 
radical, small, somewhat fleshy; petioles stout, flattened, +-4in. 
long; blade 4-2in. diam., cuneate or obovate-cuneate, with 3-8 
acute or obtuse teeth or lobes. Scape short, stout, 1-flowered, 
4-lin. high. Flowers }-$in. diam. Sepals 5, silky, linear-oblong, 
membranous. Petals 8-15, linear-obovate, with 1 or sometimes 3 
glands a little distance above the base. Receptacle hairy. Achenes 
forming a globose head 4in. diam., turgid, rounded, glabrous or 
with a few long weak hairs; style stout, subulate.—Kirk, Students’

SoutH Isnanp: Otago—Lake district, Hector and Buchanan! Old Man 
Range, Hector Mountains, Mount Pisa, Mount Cardrona, Mount Tyndall, 
Petrie ! Altitudinal range 4000-7000 ft. January—March. 
A singular little plant, of very peculiar habit and appearance. It is not 
allied to any other species of the creeping section of the genus, and would 
perhaps have been better placed in the vicinity of £. sericophyllus. 
32. R. macropus, Hook. f. in Hook. Ic. Plant. t. 634.—Per- 
fectly glabrous, smooth and succulent, 6-18in. high. Stems long, 
fistulose, creeping and rooting at the nodes. Radical leaves on 
petioles varying in length from 4—18in.; blade 1-24 in. in diam., 
semicircular, flabellate or reniform in outline, 3-5-partite to the 
base ; leaflets broad or narrow-cuneate, more or less deeply and 
irregularly lobed or cut, lobes toothed at the tips. Flowering-stem 
about as long as the radical leaves, bearing 2 or 3 small cauline 
leaves, opposite to each of which springs a long or short 1-flowered 
peduncle. Flowers small, seldom more than din. diam. Sepals 5, 
oblong or obovate. Petals 5, longer or shorter than the sepals ; 
gland basilar. Achenes forming a small globose head, turgid, 
glabrous ; style long, subulate.—Hundb. N.Z. Fl. 7 ; Kirk, Students’ 
Fl.17. RB. longipetiolatus, Col. im Trans. N.Z. Inst. xxv. (1893)

NortH anp SoutH Isiranps: Not uncommon in swamps in lowland dis- 
tricts from the Kaipara River to the south of Otago. December—January.
