NOETH Island : on sea-oliffs, Colenso, Bishop WilUams ! 



Distinguished from S.pumiceus at sight by the zigzag stem and branches, the glaucous leaves, 

 and the peculiar branching of the corymb. I have not seen an authenticated specimen, and the 

 matierial at, my command is but scanty. 



11. S. pumiceus, Col. in Trans. N.Z.I, xxi. (1888) 89. A rather stout 

 erect glabrous or glabrate herb, 2ft.— 5ft. high. Stems striate, slightly flexuous, 

 erect or suberect, branched above, Leaves coriaceous or subcoriaceous, shining, 

 3in.— 4in. long, lin.— IJin. broad, broadly oblong, amplexicaul sessile, acute or 

 obtuse, broadly auriculate ; margins irregularly and distantly serrate or sinuate- 

 serrate ; veins prominent beneath ; upper leaves smaller, oblong to lanceolate. 

 Branches of corymb stout, erect. Heads few or many, about Jin. broad ; invo- 

 lucral bracts and florets as in S. Banksii. Achene shorter, rather stout, grooved, 

 not narrowed above, sparingly pubescent. — S. Banksii, /3. velleia, Hook, f., Fl. 

 N.Z. i. 146. S. scabrosus, Banks and Sol. MSS. 



Var. angustatus. Stem less robust, sparingly clothed vyith scattered hairs. Leaves ljin.-3in. 

 long, Jin.-Jin. broad, subcoriaceous ; lower lanceolate, acute or acuminate, irregularly toothed or 

 sinuate, narrowed into slightly winged petioles, auricles small ; upper sessile, auricle larger ; veins 

 le?3 prominent than in the typical form. — 8. Banksii, var. y scabrosus. Hook. I., I.e.

 Banks and Sol. I Bast Cape Island, Ross I Between Tolaga and Poverty Bay, Colenso. Near 

 Table Gape, A. Hamilton ! 



The Banksian specimens belong to the typical form ; they are less coriaceous than those 

 collected by Hamilton, and have a few soabrid hairs on the superior surface of the midrib. 



12. S. glaucophyilus, Cheesem. in Trans. N.Z.I, xxviii. (1895) 536. 

 Rootstock stout, woody. Stems herbaceous, 1ft.— 3ft. high, glaucous, much 

 branched, glabrous, strongly grooved, naked at the base or furnished only with 

 minute scale-like leaves. Leaves numerous, 2in.— 4in. long, Jin.— lin. wide, 

 oblanceolate oblong-obovate or obovate-spathulate, obtuse or subacute, sinuate- 

 dentate or serrate, gradually narrowed into broad flat petioles, not dilated at 

 the base, very glaucous, somewhat thickened at the margins ; upper leaves 

 narrower, lanceolate or linear-lanceolate, serrate, passing into narrow-linear 

 entire bracts. Heads several in a loose terminal corymb, broadly campanulate ; 

 involucral bracts linear, acuminate, 2- ribbed, glabrous, pilose at the tips. Ray- 

 florets about 15. Disk-florets numerous. Achenes not seen.
