CHATHAM Islands, Dieffenbach, Bishop Williams I O. Mair ! H. H. Travers ! Cox ! Hanga- 

 tara. Nov., Dec. 



On margins of woods near the sea. Distinguished from all other species of this section by the 

 narrow acute leaves, slender peduncles, smaller heads, and purple rays. Mr. Cox states that a 

 white-rayed form, called makora by the natives, is occasionally found.

 branched shrub, oft.— 6ft. high. Branches robust, tomentose. Leaves exceed-

 late or oblong-lanceolate, narrowed into a short broad petiole, acute, serrate or 

 with teeth with obtuse callous tips, white with loosely-appressed tomentum beneath,

 rather slender peduncles with few linear bracts ; involucral bracts 2-seriate, the

CHATHAM Islands : Travers I Enys ! Cox I In swampy places on the higher parts of the 

 islands and on high cliffs. Keketerehe. Nov., Dec. 



This fine plant is distinguished from 0. operina and 0. angustifolia by the broader leaves, 

 slender peduncles, and few linear bracts. There is some reason to think that two species are 

 included under this description. 



3. O. operina, Hook.f., Fl. N.Z. i. 115. An erect sparingly-branched 

 shrub, 6ft.-12ft. high. Branches stout, loosely tomentose. Leaves very coria-
