A well-marked plant, easily known by the large linear leaves clothed with rusty 
tomentum beneath, and transversely rugose from the numerous main veins spreading at 
right angles to the midrib. In the “ Illustrations of the New Zealand Flora” I suggested 
that Buchanan’s O. alpina was identical with O. lacunosa. This has been proved to be 
the case by Mr. Petrie, from an actual inspection of the locality from which O. alpina was 
originally obtained. See his remarks in Trans. N.Z. Inst. xl (1908) 295-96.

A small densely branched shrub 4-8 ft. high, rarely more; branches stout, 
yellowish-brown, marked with the scars of the fallen leaves, leafy at the top 
only. Leaves closely packed, mixed with short pointed scales, articulated 
at the base of the short petiole, alternate, coriaceous, 2-5 in. long, ;5-4 in. 
broad, narrow-linear, quite entire or faintly sinuate, acute, margins very 
strongly revolute, often almost to the midrib, upper surface with a deep 
longitudinal groove and shallow transverse ones, under-surface with a stout 
and prominent rounded midrib, lateral veins strong, cutting up the surface 
into numerous sunken interspaces, the whole under-surface more or less 
clothed with yellowish-white floccose tomentum. Inflorescence at the tops 
of the branches, but good specimens not seen, apparently springing from 
clusters of short scale-like leaves. Panicles small, short, apparently with
