Senecio. | COMPOSITE. 373 
membranous, rather succulent, 2-5in. long, lower narrowed into a 
petiole, upper sessile with broad amplexicaul auricles, deeply and 
irregularly pinnatifid; segments few, 1—2in. long, acute, toothed 
or lobed or almost pinnatifid, glabrous above, mealy-tomentose 
beneath. Corymbs terminal ; peduncles slender, bracteate. Heads 
numerous, discoid, 44in. diam.; involucre broad, campanulate ; 
bracts about 20, in 1 series, linear-lanceolate, acute, 2-ribbed, 
margins scarious. Florets all hermaphrodite, very numerous, 
funnel-shaped. Achenes linear - oblong, grooved, glabrous or mi- 
nutely puberulous. 
AntipopEs Isntanp: Kirk! January—February. 
A yery distinct species, quite unlike any other found in New Zealand. Kirk 
compares it with the Fuegian S. candidans, but that has ovate leaves with 
crenate-toothed margins. 
7. S.lautus, Yorst. Prodr. n. 538.—-An exceedingly variable much 
or sparingly branched glabrous or pubescent annual or biennial 
herb 6-24in. high; stems stout or slender, erect or decumbent or 
almost prostrate, grooved, flexuose. Leaves 1—-2in. long, linear or 
linear-lanceolate, more rarely broader and lanceolate or linear- 
oblong to oblong, either narrowed into a petiole or dilated with 
stem-clasping auricles at the base, entire or remotely toothed or 
lobed or pinnatifid ; lobes narrow or broad. Heads in few- or many- 
flowered corymbs, 4—2in. diam., campanulate; involucral bracts 
herbaceous, linear, acute, pubescent at the tips, usually prominently 
2-ribbed ; outer bracts few, small. Ray-florets 10-15, with spread- 
ing or revolute ligules, rarely absent. Disc-florets numerous, 
scarcely longer than the involucre. Achenes linear, grooved, 
pubescent or nearly glabrous. Pappus-hairs copious, soft, white.—

This is a widely diffused plant in Australia and Tasmania as well as New 
Zealand, and is everywhere exceedingly variable, not a few forms having been 
described as distinct species. The chief varieties found in New Zealand may 
be briefly characterized as follows, but it must be borne in mind that inter- 
mediates are not uncommon ;— 
Var. a.—Much branched, erect or decumbent. Leaves deeply pinnatifid ; 
segments long and narrow, often again toothed, rarely short and broad. 
Heads 4-4in. diam., radiate.—Usually near the coast, but occasionally found 
inland. Mr. Kirk’s variety carnosulus is probably a form of this. 
Var. montanus.—Sparingly branched or quite simple, erect. Leaves oblong 
to lanceolate or spathulate, entire or toothed or shortly pinnatifid. Heads 
—3in. diam., radiate ; rays often revolute.—A common mountain plant in both 
the North and South Islands.
