Olearia Lyallii. 



FIGUBE 46. 



This plant was introduced by Mr. F. A. D. Cox, and is a native of 

 Ewing Island, in the Auckland Islands group, where the whole island 

 is covered with it; and also on the Snares it forms a forest of large 

 shrubs or small trees 15 to 20 feet high, sometimes reaching 30 feet, 

 with trunks 18 to 24 inches in diameter. Leaves 4 to 8 inches long, 

 elliptic ovate or orbicular ovate, abruptly acuminate, shortly petiolate, 

 very rigid and coriaceous, white with floccose tomentum above, but 

 becoming glabrous when old; under surface densely clothed with soft 

 white wool; margins irregularly doubly crenate. Eacemes terminal, 

 stout, 4 to 8 inches long ; heads large, IJ to 1-| inch diameter, dark brown. 

 The foliage is quite magnificent, but the flowers are somewhat dis- 

 appointing. The plants grow in a sandy peat, and like a moist climate. 

 Since my visit to New Zealand in 1908 Dr. L. Cockayne has found 

 growing on Stewart Island plants practically identical with the above, 

 which so far had only been identified as 0. Col&nsoi. 



This species of the Carrot family has not yet been properly 

 classified. The plant is extremely rare now on the islands, and is only 

 found in places inaccessible to stock, which devour it greedily wherever 

 they can get at it. I found it growing on the precipitous western 

 cliffs of Chatham Island, and was shown a large patch of it growing 

 on a semi-detached cliff-island, which I examined, but only found it in 

 seed, except the plant here shown. Unfortunately, the specimens sent 

 to Mr. Cheesman in New Zealand were in such a bad state of preserva- 

 tion when they arrived as to be useless for identification. Mr. ^ 

 Cheesman says, in his " Flora of New Zealand," that the fruit of thisj 

 is quite unlike Aciphylla, Ligusticum, or Angelica, to all of whichj 

 genera it has been referred.
