9 R. Grahami Petrie in Trans. N.Z. Inst. xivi (1914) 32.—Short, 
stout, erect, thick and fleshy, 3-Din. high. Rootstock stout, putting 
down many stringy rootlets. Radical leaves 5-4, seldom more; petioles 
long, with broad sheathing bases, the margins of which are furnished 
with white silky hairs. Blade 1$-2in. diam., thick and coriaceous, 
clabrous, except a few silky hairs on the margins, reniform in outline, 
cut down nearly to the base into 3 broadly cuneate segments which are 
again cut and lobed. Scape rather longer than the leaves, 1—3-flowered ; 
cauline leaves 1-2, similar to the radical, but smaller but less divided. 
Flowers large for the size of the plant, 9-lin. diam., bright-yellow. 
Sepals 5, broadly oblong, obtuse, silky externally. Petals 5-10, narrow- 
obovate, obtuse, a glandular pit near the base; stamens very numerous, 
in several series. Receptacle broadly oblong or nearly orbicular. Achenes 
somewhat turgid, shortly 2-winged at the base ; style short, curved. 
SoutH Isutanp: Mount Cook district-—Coronet Peak, head of Tasman Valley ; 
rocks of Aiguille Roque, south of Malte Brun, P. Graham, 8000 ft. alt. 
This, which appears to be a perfectly distinct species allied to R. pinguis, was 
discovered by Mr. P. Graham, chief guide to the Hermitage, who sent flowerless 
specimens to me in 1910 collected on Coronet Peak. Much more complete material 
is required before a satisfactory diagnosis can be prepared. 
10. R. nivieola Hook. Ic. Plant. (1844) tt. 571, 572.—Hrect, usually 
rather slender, paniculately branched above, 2-3 ft. high, more or less 
covered with long soft white spreading hairs or nearly glabrous. _ Root- 
stock short, stout. Radical leaves on long petioles 4-12in. long with 
broad sheathing bases; blade 3-6in. diam. or even mote, cordate-reniform, 
more or less deeply -3-7-lobed, lobes broadly cuneate, inciso-crenate. 
Cauline leaves deeply cut and lobed, upper laciniate. Flowers many, 
large, golden-yellow, 1-1$in. diam. Sepals 5, linear-oblong, pilose. Petals 
usually numerous, 8-15, narrow cuneate-obovate, emarginate, each with 
a single glandular pit near the base. Achenes forming a small rounded 
head, glabrous, turgid; style straight, hooked at the tip.—Hook. f. Fi.

A remarkably graceful and beautiful plant. It is a great ornament of the 
subalpine flora of Mount Egmont, where it is more abundant than in any other 
locality known to me.
