Family Rosaceae.
Rubus australis Forst. f. var. glaber Hook. f. [J. F. A.; J. B. A.; L. C.]
Abundant in the forest.
Rubus cissoides A. Cunn. [J. B. A.]
In the forests; abundant.
Var. pauperatus Kirk, though sometimes found in the forest, is more often found in the open, chiefly on the sites of old forests. [J. B. A.; L. C.]
Rubus schmidelioides A. Cunn. [J. B. A.] var. coloratus Kirk [L. C.]
Common on the margin of the forests, and in rocky ground above the forests.
Rubus subpauperatus Cockayne. [L. C.]
Common near the outskirts of the forest.
Potentilla anserina Linn. var. anserinoides Raoul. [R.; J. F. A.; J. B. A. L. C.]
In swampy ground occasionally. (Akaroa is the type-locality.)

°Geum urbanum Linn. var. strictum Hook. f. [J. F. A.; J. B. A.; L. C.] Tussock pastures: Cockayne.
Acaena novae-zelandiae Kirk var. viridissima Bitter. [J. B. A.; L. C.]
This is the most abundant form of Acaena on the peninsula, and is everywhere common up to 1,600 ft., particularly in dry open ground. In the forest it is usually replaced by the following, which, however, is by no means so common.
Acaena Sanguisorbae Vahl. var.
This variety is thus described from my specimens by L. Cockayne in a letter to me: “Plainly to be distinguished by the dark dull green and but slightly hairy upper surface of the leaf, the silvery undersurface with closely appressed hairs, the sepals green edged with purple within and still more hairy and purple without, the frequently trifid stipules, and the rather short stout spines, which vary from pale to rather dark purple.” This variety, comparatively rare on the Lyttelton Hills, occurs frequently on the peninsula above 1,500 ft., and at all levels in the forest.
Acaena Sanguisorbae Vahl. var. pilosa Kirk.
This form as described by Kirk occurs on the southern slopes of Castle Rock and Mount Herbert above the height of 2,000 ft., probably also at Cooper's Knobs. It is at once distinguished from the preceding by its glaucous bluish coloration, with brown serrations. The undersurface of the leaf, the upper margin, the petiole, peduncles, and stem are all markedly pilose. (I am indebted to Dr. Cockayne, who is making a special study of the New Zealand species of the genus, for this identification).
A fourth form of Acaena (Acaena Sanguisorbae Vahl. var. viridior Cockayne) occurs in a small piece of bush in the Wainui Valley.
J. B. A. gives also (2)A. adscendens, but I do not think it occurs.
