Host: Anistome filifolia (Hook. f.) Cockayne and Laing. On leaves and stems. Herb. No. 742. II, III. Table Bay, Wakatipu (Otago), 830 m., W. D. Reid ! 23 May, 1922. (Type.)

0, I. Unknown.
II. Uredosori amphigenous, chiefly hypophyllous, and caulicolous, elliptical, 0.25-1 mm. long, scattered or crowded, bullate, pulverulent, cinnamon-brown, becoming exposed by the longitudinal fissuring of the epidermis. Spores elliptical, obovate, or subglobose, 22-35 X 18-25 mmm.; epispore pallid cinnamon, sparsely and bluntly echinulate, 2 mmm. thick, cell-contents granular, cinnamon; germ-pores 4, equatorial, obscure.
III. Teleutosori similar to the uredosori but dark chestnut-brown. Spores elliptical or subclavate, 30-40 X 20-26 mmm.; apex rounded, not thickened, base rounded, less commonly attenuate, both cells about the same size; slightly constricted at the septum; epispore minutely verruculose, chestnut-brown, 1-5-2 mmm. thick, cell-contents granular; pedicel persistent, hyaline, fragile, up to 30 X 6 mmm.; germ-pore of the upper cell apical, conspicuous, basal pore 2 below the septum, obscure.

0, I. Incognitis.
II. Uredosoris amphigeniis, praecipue hypophyllis et caulicolis, ellipticis, ad 0.25-1 mm. longis, raris vel catervis, bullatis, pulverulentibus, cinnamomees, din tectis ad extremum expositis rupta epidermide. Uredosporis ellipticis, obovatis vel, subglobosis, 22-35 X 18-25 mmm.; episporio pallido-cinnamomeo, raro rustice echinulato, 2 mmm. crasso, contentu granuloso, cinnamomeo; foraminibus germinis 4, circulis, obscuris.
III. Soris teleutosporiferis uredosoris similibus, castaneo-fuscis. Teleutosporis ellipticis vel subclavatis, 30-40 X 20-26 mmm.; apice rotundato, non incrassato, basi rotundato raro attenuato; ad septum leniter constrictis; episporio subtiliter verruculoso, castaneo, 1.5-2 mmm. . crasso, contentu granuloso; pedicello persistence, hyalino, delicato, ad 30 X 6 mmm.; foramine germinis cellulae superioris apicale, conspicuo, foramine basali s infra septum, obscuro.

This species is separated from the preceding on account of the minutely -verruculose epispore of the teleutospores, sparsely -warted cinnamon-coloured epispore of the uredospores, and different sorus characters. Although both occur on the same host, they show little other than a general resemblance to each other.

Cunningham (1931a) stated that in the original description of this species the host was erroneously listed as Anisotome filifolia. All hosts [Anisotome spp.] are endemic and confined to mountainous districts in the South Island. The rust is occasionally found in the mountainous districts in Otago and Canterbury.
