Var. elegans Cockayne in Trans. N.Z. Inst. xliv (1912) 9.—Altogether similar to 
the type, but flowers always pink. T. dy ( ion) BLO - 
CHATHAM Istanps: Not uncommon on coastal cliffs, but seldom seen far from 
the sea, H. H. Travers, J. D. Hnys! F. A. D. Cox! Cockayne. 
Differs from all the forms of G. dissectum, to which it was referred by the late 
Baron Mueller, in the silvery-hoary pubescence, 1-flowered peduncles, large flowers, 
and minutely reticulated seeds. | +

4. G. pilosum Fok ak f. Prodr. (1786) n. 531.— Rootstock usually 
stout and swollen, sometimes 1 in. thick. Stems 1-2 ft. long, branched, 
decumbent at the base, ascending above, often covered with soft spreading 
or retrorse hairs, rarely almost glabrous. Lower leaves on slender petioles 
4-6 in. long which are usually covered with spreading or reversed hairs ; 
upper leaves on shorter petioles, uppermost sessile. Lamina cut to the 
base or nearly so into 5-7 segments, which are again deeply lobed or 
partite ; lobes cuneate, more or less rounded at the top. Stipules lanceo- 
late, acuminate. Peduncles equalling the petioles in length, usually set 
with spreading hairs, but sometimes subglabrous, 1—2-flowered, bracteate. 
Flowers very variable in size. Sepals ovate, abruptly acuminate. Petals 
exceeding the calyx, obcordate, emarginate. Carpels hairy, even.— Willd.

long as the calyx, $in. long or more.—G. patulum /forst. f. Prodr. (1786) n. 530. 
NortH AND SoutH Istanps: Abundant from the orth Cape southwards. Sea- 
level to 2000 ft. 
I have followed Kunth’s monograph of the family in separating Forster’s 
G, pilosum from G. dissectum. I find that Mr. Maiden, in his ‘‘ Census of New South 
Wales Plants,’’ had previously taken the same course, remarking that “ G. dissectum 
is an annual with a thin root, and G. pilosum a perennial (or rarely biennial) with a thick 
fleshy root.”’ 
5. G. microghyllum Hook. f. Fl. Antarct. i (1844) 8, t. 5.—A slender 
much-branched prostrate and straggling perennial 6-18 in. long, more or 
less pubescent with appressed silky white hairs, which are sometimes 
retrorse on the peduncles and pedicels. Leaves on long slender petioles ; 
blade $-lin. diam., orbicular in outline, cut to the middle or below 
into 3-7 broad or narrow obcuneate lobes, which are more or less deeply 
toothed at the tips ; stipules small. Peduncles 1-flowered, rarely 2-flowered ; 
flowers usually white. Sepals ovate-lanceolate, barely awned. Petals 
longer than the sepals, entire or slightly retuse. Carpels smooth and even, 
pilose. Seeds longitudinally striated, reticulations long and narrow, not 
conspicuous.—Hook. f. Handb. N.Z. Fl. (1864) 36; T. Kirk Students’ FI. 
(1899) 80; Cheesem. Man. N.Z. Fl. (1906) 89. G. potentilloides Hook. f. 
Fl. Nov. Zel. 1 (1853) 40 (not of L’Herit). G. dissectum var. potentilloides 
Benth. Fl. Austral. 1 (1863) 296. 
NortTH AND SoutTH IsLanps, Stewart Is~tanp, AuckLAND IsLanps: Common 
from the North Cape southwards, ascending to 3000 ft. Endemic. 
This differs from all the forms of G@. dissectum in the more slender habit, less 
deeply lobed and smaller leaves, 1-flowered peduncles, paler flowers, and in the much 
smaller and narrower reticulations on the seeds. The Australian and Tasmanian plant 
referred by Bentham to G. dissectum as var. potentilloides is now considered by Kunth 
and other botanists to be the same as G. microphyllum. :
