This is evidently a distinct species, although clearly allied to the O. furfuracea 
group. But it is readily separated by the large oblong-obovate leaves, which are 
remarkable for their thinly coriaceous texture, finely reticulated veins, and the delicate 
thin and silvery tomentum of the under-surface. The species is named in honour of 
Mr. W. A. Thomson, of Dunedin, who has kindly supplied me with flowering specimens 
cultivated in his garden at Half-way Bush, Dunedin.
