1018 COMPOSITAE. | Senecio. 
veins reticulate, margins sinuate and finely spinulose-serrate. Cauline 
leaves smaller, on shorter petioles, with large leafy auricles and smaller 
narrower blades, gradually passing into lanceolate or linear entire bracts. 
Corymbs large and broad, much branched; branches slender. Heads very 
numerous, #-If1in. diameter, bright-yellow; involucral bracts in a single 
series, linear or oblong-linear, acute, glabrous or finely pubescent. Ray- 
florets 10-15; ligule narrow, spreading; disc-florets 25-35. Ripe achenes 
not seen. Pappus soft, copious, white.

A most distinct species. Although allied to S. latifolius it differs widely in habit, 
in the large cordate leaves, which are never lobulate or pinnatifid, but have their margins 
finely spinulose-serrate, in the long terete petioles, and in the larger flower-heads.

Mr. Kirk limits S. Banksii to a form with more decidedly flexuous stems and rather 
membranous glaucous leaves, keeping up Colenso’s S. pumiceus for the reception of 
those states with stouter and straighter stems and more coriaceous leaves. But a series 
of the Tolaga Bay plant, which is that collected. by Banks and Solander, shows that this 
distinction cannot possibly be maintained, some of the specimens exactly matching 
the types of S. pumceus in Mr. Colenso’s herbarium, while others show a regular gradation 
to more slender and membranous forms. An examination of the ripe achenes of buth 
varieties also proves that the supposed difference in size and shape does not exist. 
15. §. Colensoi Hook. f. Fl. Nov. Zel. 1 (1853) 147.—An erect much or
