262 NOTES ON SOME COMPOSIT;.E OF OTAGO, NEW ZEALAND. 
Scape glabrous; bractless ; about 2 in. high. Hairs most plentiful as 
usual on young leaves and petioles; long, brown, coarse, sparingly or 
copiously fringing leaf-margin. Leaf-petiole generally under 4 in. long. 
Lamina $—3 in. long, variable in form and size; suborbicular or ovate, 
or even subspathulate, apex acute; margin toothed, sometimes nearly 
entire; not more lobed about base than above; dries to a blackish- 
green. Head about $ in. in diameter. 
2. L. pinnatifida, Hook. f. Occurs in the same habitat as the pre- 
ceding, with which it is apparently sometimes intermixed and apt to 
LA. 
ROO NOB. L. Marshes on the roadsides about the For- 
bury, Dunedin ; 6-8 in. high, with yellow button-like heads; December, 
in flower, W. L. L. 
The representative in Otago of our British marsh forms of Bidens 
and Pulicaria. In my Otago plant the stem is usually 6-7 in. high. 
Leaf very variable in size and form, according to its position on stem. 
Under 2 in. long and $ in. broad; suboblong ; irregularly and sometimes 
doubly pinnatifid ; upper leaves less cut than lower, becoming 
simple or sometimes entire. Head about $ in. in diameter. 
Specimens from Nelson (Travers) in my herbarium represent alto- 
gether a much more delicate or slender, more erect plant—smaller in 
all its parts—4—7 in. high. Leaves: upper simple, linear-lanceolate ; 
lower generally 3-fid at tips, with long, linear-oblong segments, central 
largest ; never so much cut as in Otago forms; quite as glabrous ; no 
secondary division of leaf-segments. Head }— in. in diameter. Flower- 
peduncle sometimes 1} in. long, filiform, drooping. 
2. C. dioica, Hook. f. Sand dunes and swamps about mouth of 
the Kaikorai, W. L. L. 
enus X. ÉRECHTITES, 
l. E. arguta, DC. Roadsides, Caversham, Dunedin, 15-18 in. 
high; Chain Hill ranges, 18-24 in. tall; December, in flower and 
fruit, W. L. L. 
Leaf very variable in form and size, and in the number and character 
of its divisions. Sometimes 3 in. long and 2—1 in. broad, but more fre- 
quently from 4—4 in. broad. Form broadly lanceolate in larger leaves ; 
linear-oblong in the smaller; and every gradation between these ex- 
tremes. Margins revolute. Segments sometimes long and sublinear;
