Obs. I. This species lias close affinity with 0. macrophglla, Hook., but 

 differs from it in several particulars ; the sepals are narrower longer 

 glabrous and coloured, and only 1-nerved ; the corolla is coloured within 

 and there clothed with densely glandular pubescence, and the tube is much 

 shorter, and in the venation of the limb, which is also larger, the angles 

 are rounded at apices, and not acute as in that species, and the pedicels are 

 densely glandular-hairy : the leaves also are different, both in their shape 

 and in their curious little gland-like openings or depressions on their 

 margins ; and tbe scape is very much stouter and 7-angled, with its lower 

 floral leaves much more numerous, larger and petiolate. 



Obs. II. From Sir J. D. Hooker's "note"* on an imperfect specimen 

 of Ourisia of j)ossibly an additional species allied to 0. macrophylla which I 

 had early "gathered near Taupo ; " I am of opinion that this may very 

 likely be identical with that plant.
