Kirk. — On the Macrocephalous Oleaiias of N.Z. 447 



tomentinn beneath ; petiole short, stout, sheathing at the 

 base. Heads in terminal racemes 4in.-7in. long; rhachis, 

 bracts, peduncles, and outer involucral leaves white with ap- 

 pressed tomeutum, involucral leaves in from o to 8 series. 

 Florets similar to those of 0. colensoi, but darker, outer series 

 female, rayless. Achene silky, pappus-liairs in two series, 

 thickened upwards. 



Hah. The Snares and the Auckland Islands. 

 Although this grand plant differs widely from 0. colensoi in 

 appearance, it is very closely allied to that species, the chief 

 points of difference being the more open habit, stouter 

 branches, orbicular-ovate leaves, stouter petioles, and espe- 

 cially the many-seriate involucre ; but specimens may occa- 

 sionally be found which approach 0. colensoi in habit and 

 foliage. The greyish hue of this plant during the summer 

 and autumn months is most striking, and is due to the upper 

 leaf-surfaces being clothed with tomentum which is of much 

 thinner consistency than that on the lower surfaces. The 

 leaves of 0. colensoi are sparingly tomentose on the upper 

 surface of the young leaves, but the tomentum disappears 

 before the leaves are fully developed. In 0. hjalUi it is more 

 plentiful, and appears to be permanent for the first year. 

 The leaves of O. hjallii are more rigid and coriaceous than 

 those of its near ally, and they are often attacked by a 

 handsome orange-coloured fungus, Uredo oleario', Cooke, n.s.

Hab. South Island : Marlborough, from Awatere south- 

 wards to the Conway Eiver. Ascends from sea-level to 

 4,000ft. 



A robust species, of remarkable habit and great l^eauty, 

 usually forming a low spreading shrub 1ft. -3it. high, and 

 rarely attaining the extreme height of 8ft. The leaves are 

 crowded at the tips of the branches, and vary greatly in outline 

 from oblong to ovate or narrow-obovate ; they are from 3in. 

 to Tin. in length, including the petiole, and from lin. to 4in. 

 broad, shining above, excessively rigid and coriaceous, but 

 quite entire. They are densely clothed with white tomentum 

 beneath, which becomes tawny or reddish in dried specimens, 

 and sometimes projects beyond the margin, forming a narrow 

 white border ; the young leaf is usually clothed above with a 

 thin layer of tomentum, which usually disappears entirely, 

 but in some cases a narrow line is left, presenting the appear- 

 ance of a marginal nerve, which, however, can be easily 

 scra^Ded away. Peduncles 1-5, tomentose, 6in.-12in. long, 

 as thick as a goosequill, usually naked, but not unfrequently 

 one or several sessile or pedunculate clasping leafv bracts are
