The handsome Qlearia which forms the subject of our 
illustration is confined to the Chatham Islands, east of New 
Zealand, where, according to Captain Dorrien-Smith, who 
has given an account of the plant in the passage quoted 
above, it grows in compact masses on the cliff edges or 
scattered about among the upland bogs in association with 
O. semidentata, Decne, a species which, according to 
Dorrien-Smith, is even finer than O. chathamica. In its 
native habitat the plant is in flower during the months 
from November till February, each plant blooming for a 
prolonged period. Both Mr. Cheeseman and Captain 
Dorrien-Smith state that the ray-florets may at times be 
white ; the disk-florets are violet-purple. The nearest 
ally of the species in the genus Olearia is O. operina, 
Fesrvuary, 1912.
