 lobulate-pinnatifid or lyrate-pinnatifid ; upper sessile, ovate-oblong or contracted

 corymbs ; branches slender. Receptacle broad, fiat. Involucral bracts 1-seriate,

Var. rufiglandulosus {sp.), Col. in Trans. N.Z.I, xxviii. (1895) 599! Leaves about 4in. long, 

 irregularly doubly dentate ; blade ovate, deltoid, abruptly narrowed into a broadly winged and 

 toothed aurioulate petiole, glandular-pubescent or glabrate. Corymb very large ; lower branches 

 12in.-15in. long. Achene densely pubescent. 



Var. slnuatifollus. Stems very slender, flexuose, sparingly glandular-pubescent. Leaves 

 distant ; blade broadly oblong-ovate, acute or obtuse, entire, margins sinuate but not toothed, trun- 

 cate, slightly cuneate at the bass, narrowed into a long slender scarcely winged petiole with small 

 entire auricles ; midrib and veins glandular-pubescent. Heads few, small, in a short terminal 

 corymb. Branches lin. long. Peduncles and pedicels glandular. 



NORTH Island : Patangata and other places in Hawke's Bay ; local. Tryon ! Hamilton ! 



S. latifolius, DC, Prod. vi. 387, has priority, but is considered a synonym of the South 

 African S. barbellatus, DC. 



9. S. Colensoi, Hook. /., Fl. N.Z. i. 147. Stems erect, simple or much 



branched, usually woody at base, flexuose, grooved, the whole plant covered 



with cobwebby tomentum, or the leaves white beneath or on both surfaces. 



Leaves polymorphic, lin.^in. long, Jin.— IJin. broad, entire, broadly obovate to 



lanceolate narrowed into short petioles with broad wings, or oblong-ovate to 



oblong-lanceolate sessile by a broad auriculate base, rounded at the apex or 



acute with the margins sinuate, crenate, serrate, or dentate, or irregularly lobed 



or lyrate-pinnatifid, sometimes hoary on both surfaces. Corymbs usually lax. 



Heads few or many, Jin.-^in. long, campanulate. Pedicels with numerous 



bracteoles. Involucral bracts linear or oblong, acute or abruptly acuminate. 



Receptacle convex. Rays usually revolute, exceeding the tube. Disk-florets 



numerous; mouth funnel-shaped, longer than the narrow tube. Achenes 



slender, grooved, hispidulous or silky. — Handbk. 160. 



NORTH Island : sea- cliffs, Bay of Islands and Bast Cape, Colenso. Napier, Bishop Williajiis ! 

 Cape Kidnappers and other places on the coast as far south as Pourere, T. K. 



The leaves vary greatly in form and tomentum, some specimens being hoary with white 

 tomentum on both surfaces, but the florets and achenes are uniform in all. When growing in 

 places close to the sea the leaves are glabrate and very fleshy. 



10. S. Banksii, Hook. /., Fl. N.Z. 143. Glabrous in all its parts. Stem 

 erect, sparingly branched, flexuose, grooved, 2ft.-4ft. high. Leaves glaucous, 

 membranous but firm, 2in.-5in. long, lin.-2in. broad, broadly ovate-oblong, 

 subacute, sessile, amplexicaul ; auricle broad, rounded ; margins sinuate or irre-
