A noble species, nearest to D. colensoi, but differing in the pyramidal 

 or conical habit, in the large size of the lower leaves, the sub-cylindrical 

 branches and aggregated nuts. The lower branches, sometimes to the 

 height of 40 feet, are clothed with large linear leaves, giving the tree the 

 appearance of a Picea, which is increased by its habit of growth. The 

 lower branches are spreading, the upper fastigiate, and repeatedly dichoto- 

 mously branched, with the branchlets forming semi-flabellate masses at 

 the extremities. As in D. hidwillii and D. colensoi, the change from the 

 spreading linear leaf state to the mature imbricated condition is most 

 abrupt ; in some specimens the tips of the lower branches exhibit appressed 

 imbricated leaves, while the portions nearest the trunk are covered with 

 large hnear leaves, the intermixture of dimorphic foliage without inter- 

 mediate forms presenting a singular and attractive appearance. The nuts 

 are produced in greater abundance than those of any other New Zealand 

 species, and often have their receptacles lined with a singular orange- 

 coloured alveola. The nuts destitute of this lining are usually of less size. 



The petioles of the flat linear leaves have a curious half twist. 



This species is the manoao of the northern natives ; its timber is of a 

 reddish colour and of extreme durability. 



I first collected this handsome species on the Great Barrier Island in 



1867, and subsequently, under Dr. Hector's instruction, examined the 



Whangaroa habitat where he had previously discovered it. In papers on 



Northern Plants, and on the Botany of the Great Barrier Island, published 



in the first volume of " Transactions of the N. Z. Institute,"* I expressed a 



decided opinion as to its specific distinctness, but at that time I had not 



seen D. colensoi, and in deference to the opinion of Dr. Hector and Mr. 



Buchanan, who considered it a lowland form of that species, I refrained 



from giving a formal description. It was, however, published by the late 



Professor Parlatore the following year, under its present name in De 



CandoUe's "Prodromus." It is, perhaps, the most strongly marked of all 



the New Zealand species.
