Remarks. P. tenuifolium leaves and fruits have already been recorded from Central Otago shelters (Wood and Walker, 2008). Fragments of leaf cuticle are readily recognized on the basis of paracytic stomatal complexes, broad, smooth ridges marking the anticlinal epidermal cell walls, distinctive deeply staining trichome attachment sites, which usually have irregular and diffuse edges (sometimes with the persistent bases of trichomes), and occasional larger stomatal complexes. The trichome attachment sites and larger stomatal complexes are surrounded by radiating fine ridges.
