262 NOTES ON SOME COMPOSIT.E OF OTAGO, NEW ZEALAND.<br />

Scape glabrous ; bractless ; about 2 in. high. Hairs most plentiful as<br />

usual on young leaves and petioles ; long, brown, coarse, sparingly or<br />

copiously fringing leaf-margin. Leaf-petiole generally under } in. long.<br />

Lamina |-|- in. long, variable in form and size ; suborbicular or ovate,<br />

or even subspathulate, apex acute ; margin toothed, sometimes nearly<br />

entire ; not more lobed about base than above ; dries to a blackish-<br />

green. Head about ^ in. in diameter.<br />

2. L. pinnatifida. Hook. f. Occurs in the same habitat as the pre-<br />

ceding, with which it is apparently sometimes intermixed and apt to<br />

be confounded.<br />

Genus IX. Cotula.<br />

1. C coronopijolla, L. Marshes on the roadsides about the For-<br />

bury, Dunedin ;<br />

in flower, W. L. L.<br />

6-8 in, high, with yellow button-like heads; December,<br />

The representative in Otago of our British marsh forms of Bidem<br />

and PuUcaria. In my Otago plant the stem is usually 6-7 in. high.<br />

Leaf very variable in size and form, according to its position on stem.<br />

Under 2 in. long and \ in. broad; suboblong ;<br />

irregularly and sometimes<br />

doubly pinnatifid ; upper leaves less cut than lower, becoming sub-<br />

simple or sometimes entire. Head about \ in. in diameter.<br />

Specimens from Nelson (Travers) in my herbarium represent alto-<br />

gether a much more delicate or slender, more erect plant—smaller in<br />

all its parts—4-7 in. high. Leaves: upper simple, linear- lanceolate ;<br />

lower generally 3-fid at tips, with long, lineav-oblong segments, central<br />

largest ; never so much cut as in Otago forms ; quite as glabrous ; no<br />

secondary division of leaf-segments. Head \-\ in. in diameter. Flower-<br />

peduncle sometimes \\ in. long, filiform, drooping.<br />

2. C. dioica, Hook. f. Sand dunes and swamps about mouth of<br />

tile Kaikorai, W. L. L.<br />

Genus X. Erechtites.<br />

1. E. (irfjida, DC. Roadsides, Caversham, Dunedin, 15-18 in.<br />

high; Chain Hill ranges, 18-24 in. tall; December, in flower and<br />

fruit, W. L. L.<br />

Leaf very variable in form and size, and in the number and character<br />

of its divisions. Sometimes 3 in. long and f-l in. broad, but more fre-<br />

quently from \-\ in. broad. Form broadly lanceolate in larger leaves ;<br />

linear-oblong in the smaller ; and every gradation between these ex-<br />

tremes. Margins revolute. Segments sometimes long and sublinear;
