11. R. geraniifolius Hook. f. Fl. Nov. Zel. i (1853) 9, t. 3—Erect, 
slender, Speingty-braiehed, 1-2 ft. high, glabrous or occasionally villous 
with long white hairs, especially on the petioles. Radical leaves few, on 
long slender petioles 3-6in. long; blade 2-4 in. diam., broadly reniform 
in outline, deeply 3-5-lobed, sometimes to the very base; lobes either 
cuneate and crenate-toothed or -lobed or again deeply divided into narrow- 
linear segments. Cauline leaves sessile, usually much and finely divided. 
Flowers few, seldom more than 3, }-lin. diam., yellow. Sepais 5, 
oblong, glabrous or very slightly pilose. Petals usually numerous, 8-15, 
linear-oblong, rounded at the tip, with a single basal gland. Achenes 
forming a small globose head, glabrous, turgid; style short, subulate.—

Closely allied to the preceding species, but easily distinguished by the smaller 
size, more slender habit, fewer leaves (which are often very finely cut), fewer and 
smaller flowers, and by the petals being usually rounded at the tip. Mr. Kirk's 
R. verticillatus is based upon a single imperfect specimen, without locality, in Mr. 
Buchanan’s herbarium. I consider that it is a small one-flowered state of R. geranit- 
folius, with which it exactly agrees in habit, pubescence, and flowers, differing only in 
the more rounded leaf-segments, a character of little importance in a species with 
such variable foliage. 
12. R. Enysii 7. Kirk in Trans. N.Z. Inst. xii (1880) 394.—Slender, 
leafy, glabrous, 6-I15in. high. Rootstock rather stout, with numerous 
fibrous rootlets. Leaves all radical, numerous; petioles 2-6in. long, 
grooved ; blade 1-3in. diam., 3-5-foliolate or biternate ; leaflets long- 
stalked, very variable in size and amount of cutting, sometimes large 
and rounded, toothed or 3-5-lobed, at other times smaller and cut to the 
base into 3-5 narrow-cuneate incised toothed or lobed segments, occa- 
sionally pinnately divided. Scapes 1-5, longer than the leaves, simple 
or rarely with 1-2 short branches, naked or with a single stalked or sessile 
variously divided cauline leaf. Flower $-lin. diam. Sepals 5, broadly 
ovate. Petals usually 5, rarely more, broadly obovate, with a single 
basilar gland. Achenes forming a small rounded head, numerous, turgid, 
glabrous; style short, stout, straight or curved.—Students’ Fil. (1899)

Sourn Istanp: Canterbury—Ravines in the middle and upper portion of the 
Waimakariri River basin, from Bealey to Mount Torlesse, 7’. Kirk, T. £. C; Mount, 
Oxford, J. A. Holloway; Mount St. Bernard, A. Wali. Otago—Near Lake Harris, 
T. Kirk (Students’ FI. (1899) 13). Altitudinal range 2000-4000 ft. December- 
February. 
In the first edition of this work I included within the circumscription of this 
species Buchanan’s R. tenuis (Trans. N.Z. Inst. xx (1888) 255, t. 12), said to have 
been gathered by him on the East Taieri Hills, Otago, and at Masterton; but I have 
been unable to obtain specimens from either locality, and as Buchanan’s plate differs 
from the typical state of R. Hnysi: in the more pinnately divided leaves I have 
thought it best to exclude it for the present. I have retained, however, Mr. Kirk’s 
Lake Harris locality, on the ground that Mr. Kirk, from his frequent visits to the 
Upper Waimakariri, was perfectly well acquainted with R. Hnysii, and not at all 
likely to confound another plant with it.
