who collected them. Having cultivated them for two or three years, I now 

 feel satisfied that they are specifically distinct from the Auckland Island 

 S. polaris, Planch., which has been cultivated in the garden for many years, 

 and which flowered freely three years ago. I therefore propose to distin- 

 guish the Stewart Island plant as S. lyallii, in honour of Dr. Lyall, who 

 first collected it. Unfortunately I have not been able to obtain flowers or 

 fruit, but there is no doubt as to the genus. The leaves of S. lyallii are 

 reniform, 4-8 inches across or more, with a closed — not open — sinus, 

 rather bluntly bi-serrate, not coarsely lobed, perfectly glabrous, polished 

 and shining above, wanting the stout bristles of S. polaris, below dull, with 

 a few scattered white hairs. The petiole is truly terete, striated and clothed 

 with soft white hairs, not flattened and deeply channelled as in S. polaris. 

 In 8. polaris the upper surface of the leaves is ribbed, or much wrinkled, 

 but quite smooth in my plant, which is also by far the handsomer of the 

 two, although the black shiny fruit of S. polaris is very ornamental. 

 Olearia angustata, Armstrong. 



I find that this plant has been described by Mr. Kirk as 0. oleifolia."^ My 

 name however, has several years priority, having been used in gardens for the 

 past ten years. The plant was first collected by Messrs. J. F. Armstrong 

 and W. Gray m thek exploring tour in the upper Eangitata valley in the 

 year 1869. 



I have another new species of Olearia from Stewart Island, collected 

 by the Eev. Mr. Stack. It bears considerable resemblance to 0. nitida in 

 the foliage, but the leaves are cordate, entire, and larger than in that species. 

 It has not yet flowered. Another species of the same genus, brought from 

 the Tararua mountains by Mr. H. Budding, may also be new. It was sent 

 as 0. lacunosa, but differs from that plant in the leaves being much narrower, 

 longer, less distinctly lacunose, more deeply revolute, nearly glabrous above, 

 and in the strong white midribs. It has not flowered with us. The true 

 0. lacunosa was first collected by Mr. J. F. Armstrong, in 1865, in Canter- 

 bury. 



Celmisia linearis, n.sp. 



A small, perennial, tufted, aggregated herb. Stem erect, simple or 

 branched, covered with the sheathing bases of old leaves, very stout for the 

 size of the plant. Leaves densely imbricated, 2-3 inches long, ^ to ^ broad, 

 linear, sub-acute, coriaceous, not rigid, covered above with persistent pellicles 

 of appressed silvery hairs ; below with silvery white glistening tomeutum, 

 which becomes brown with age. Convex by the recurvature of the margins. 

 Midrib sunken above, keeled below ; sheaths often 1 inch long, broad and
