Host: Olearia insignis Hook. f. On leaves. Herb. No. 778. Woodside Creek, Wharanui (Marlborough), B. H. Atkinson ! 3 Nov., 1922.
II. Uredosori hypophyllous, seated on pallid spots visible on the upper surface, orbicular, 1 mm. diam., bullate, reddish-orange, pulverulent, deeply buried in the dense tomentum of the leaf-surface. Spores elliptical or obovate, 35-55. X 26-34 mmm.; epispore hyaline, coarsely and moderately echinulate, 2-2.5 mmm., thick, cell-contents granular, reddish-orange; germ-pores indistinct.
II. Soris uredosporiferis hypophyllis, in inaculis pallidis, rotundatis, 1 mm. latis, bullatis, rubro-aurantiacis, pulverulentibus diu tomento folii tectis. Uredosporis ellipticis vel obovatis, 35-55 X 26-34 mmm.; episporio hyalino, sparse rustice echinulato, 2-2.5 mmm. crasso, contentu granuloso, rubro-aurantiaco; foramine germinis non conspicuo.
The host is endemic, and is confined to the Marlborough District. (Cheeseman, 1906, p. 279.)
In size and shape the spores of this species resemble the preceding; it is separated on account of the thicker, coarsely and moderately echinulate epispore, and bright reddish-orange colour of the sori.
