not uncommon. AUCKLAND Isnuanps: Hooker, &c. CHATHAM ISLANDS: 
Buchanan. Only known inland on the shores of Lakes Rotorua, Tarawera, 
and Taupo. Septem ber—November. Also found in southern Chili. 
A distinct little species, easily recognised by its creeping and matted 
habit, trifoliolat» leaves with nearly entire leaflets, short scapes, and spathulate 
petals. Mr. Colenso’s herbarium contains no specimens of his R. uniflorus 
(Trans. N.Z. Inst. xxxi. (1896) 267). The description agrees with R. acaulis in 
most points, but the plant is said not to be stoloniferous, and to possess a 
sheathing bract on the upper part of the scape. 
35. R. crassipes, Hook. f. Fl. Antarct. ii. 224, t. 81.—Smooth, 
glabrous, succulent, stems creeping and rooting at the nodes. 
Leaves on petioles 1-4in. long; blade cordate-reniform in outline, 
4-lin. diam. or more, 3-lobed or 3-partite; segments variable in 
shape, broad or narrow, cuneate at the base, deeply and irregularly 
toothed. Peduncles axillary, stout, erect, shorter than the leaves. 
Flowers small, +-4in. diam. Sepals 4-5, ovate, obtuse, mem- 
branous. Petals the same number, slightly longer than the se- 
pals, obovate-spathulate, with a gland a little below the middle. 
Achenes forming a rounded head +in. diam., broadly ovate, 
turgid; style short, straight.—Kirk, Students’ Fl. 17. 
Macquanris Isuanp: A. Hamilton! Also found in Kerguelen’s Island. 
The closely allied R. biternatus, Smith, from Fuegia, the Falkland Islands, 
and Marion Island, may possibly occur in Macquarie Island or the Auckland 
Islands. It can be recognised at once by its biternate leaves. 
36. R. Limosella, /’. Muell. ex Kirk in Trans. N.Z. Inst. iii. 
(1871) 177.—Small, slender, perfectly glabrous. Stems filiform, 
creeping and rooting at the nodes, often forming matted patches. 
Leaves solitary or in tufts of 2-3 at the nodes, 3-3 in. long, very 
narrow linear, usually dilated at the tip and subspathulate, obtuse, 
nerveless. Peduncles filiform, axillary, solitary, much shorter than 
the leaves. Flowers minute, +in. diam. Sepals 4, rounded-ovate, 
membranous. Petals 4, much longer than the sepals, narrow- 
linear, revolute at the tip; gland some little distance above the 
base. Achenes 8-12, rounded, somewhat turgid; style long, 
slender, recurved.—Kirk, Students’ Fl. 19. BR. limoselloides, F’.
