Macquarige Istanp: Swampy places in the lower part of the island, Dr. Scoit, 
A. Hamilton! H. Hamilion ! 
In the first edition of this work I followed Sir J. D. Hooker in placing the 
Macquarie Island plant in his R. crassipes, which can only be separated from the 
Huegian k. biternatus by its greater size and less-divided leaves. But these are 
characters of small importance, and in my Report on the Systematic Botany of the 
Islands to the South of New Zealand I adopted Dr. Schenk’s view that the two species 
should be united. The range of R. biternatus will therefore be from Fuegia and the 
Falkland Islands to South Georgia, Kerguelen, Crozets, Marion Island, New Amsterdam, 
and Macquarie Island.

177.—Small, slender, perfectly glabrous. Stems filiform, creeping and 
ropting at the nodes, often forming matted patches. Leaves solitary or 
in tufts of 2-3 at the nodes, $-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, tin. 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.—T, Kirk Students’ Fl. (1899) 19; Cheesem. Man. N.Z. Fl. (1906)

A very peculiar little species, readily known by the narrow-linear spathulate 
leaves and minute tetramerous flowers. Sir J. D. Hooker has compared it with the 
Falkland Islands &. hydrophilus, and with R. Moseleyi from Kerguelen Island, so 
far as habit and leaves are concerned. In the flowers and fruit it differs largely from 
both.
