Kuiii.— On the Macroccpludous Oleavias of N.Z. 443 



Gabnardia pallida, Hook, f., Fl. Antarct., i., 86. Akpyruvi 



pallidum, Hook, f., FI. N.Z., i., 268, t. 62c, from the 



Euahine Mountains, Euapehu, and Campbell Island. 



Appears to nie to belong to Centrolepis rather than to Gai- 



mardia, in which it was doubtfully placed by its learned 



author. It has the habit of C. vionogyna, Benth., and the 



carpels are superposed, although usually one of thern becomes 



absorbed ; the bracts are nuich more like those of Centrolepi& 



than Gaimardia. Its position is somewhat intermediate, and 



there is much to be said in favour of maintaining E. Brown's 



genus Alepi/rum for its reception as proposed by Hieronymus.

Olcaria is restricted to New Zealand and Australia, the 

 species of each country being endemic, and exhibiting a re- 

 markable amount of variation in habit, from dwarf slu'ubs ta 

 trees 40ft. high, with solitary, racemose, or paniculate in- 

 florescence, some of the forms being of great beauty. The 

 species with large solitary or racemose flower-heads are, how- 

 ever, the most attractive to the cultivator, and possess the 

 greatest amount of interest for the botanist. As the published 

 descrinf^ions of some of the forms included in this section are 

 imperfect owing to paucity of material, it is desirable to revise 

 them when needed, and to state their chief characteristics and 

 their distribution more fully than has hitherto been attempted. 



In this section the leaves may be narrow-lanceolate, oblong 

 or ovate, or orbicular-ovate, and are the largest to be found in 

 the genus ; their margins may be entire, or sharply serrate or 

 crenate, or doubly serrate or crenate ; in several species the 

 teeth are obtuse, rounded, and callous, but in all cases the 

 texture is exceedingly coriaceous ; the under-surface, or rarely 

 both surfaces of the leaf, are clothed with appressed white 

 tomentum ; and the leaf is either distinctly petioled or nar- 

 rowed at the base into a flat-winged petiole. 



The flower-heads are invariably terminal, although subse- 

 quent to flowering their position is often obscured by the 

 elongation of the shoot ; they may be solitary or racemose but 

 are never paniculate, and the peduncles may be naked or 

 clothed with linear or imbricating or foliaceous bracts. The
