Hosts :— Phormium tenax Forst. On leaves. Herb. Nos. 755, 775. Plimmerton (Wellington), 20 m., R. Waters! H. Drake! G. H. C. 16 Jan., 1922. (Type.) Phormium Colensoi Hook. f. Herb. No. 757. Tokaanu - Waiouru Road, Taupo, 800 m., E. H. Atkinson! 11 March, 1922. Both hosts are indigenous, the former being common throughout, and extending to Norfolk Island, whilst the latter is endemic. (Cheeseman, 1906, p. 716.) This rust is characterized by the small spores, coloured coarsely and sparsely echinulate thick epispore, and conspicuous scattered germ-pores. Severely infected leaves are useless for milling purposes. 7. Uredo Rhagodiae Cooke and Massee. (Fig. 119.) Chenopodiaceae. Cke. et Mass., Grev., vol. 15, p. 99, 1887. II. Uredosori amphigenous, chiefly hypophyllous, scattered, bullate, reddish-brown, orbicular, 1–1.5 mm. diam., long covered, at length free and surrounded by the ruptured epidermis. Spores globose or obovate, 22–30 × 20–23 mmm.; epispore cinnamon-brown, sparsely and moderately echinulate, 2–2.5 mmm. thick, cell-contents granular, cinnamon-brown; germ-pores scattered, numerous (8–10), conspicuous. Host: Rhagodia nutans R. Br. On leaves. Herb. No. 294. Seashore, Seatoun (Wellington), E. H. Atkinson! G. H. C. 27 Jan., 1921. Distribution: Victoria. The host is indigenous, and is not uncommon on rocky areas near the sea-coast; it occurs also in eastern Australia. (Cheeseman, 1906, p. 578.) The spore-measurements (20 × 15 mmm.) given by Cooke and Massee are much too small, as has been ascertained by McAlpine (1906, p. 207) from an examination of part of the type material. 8. Uredo inflata Cooke. (Fig. 120.) Umbelliferae. Cke., Grev., vol. 19, p. 48, 1890. II. Uredosori amphigenous, crowded or scattered, seldom confluent, irregular in shape, usually elliptical when up to 4 mm. long, bullate, pallid ferruginous, long covered by the epidermis. Spores globose or shortly elliptical, 25–35 × 22–32 mmm.; epispore hyaline, minutely and densely verruculose (appearing smooth when wet), up to 6 mmm. thick, slightly thickened at the apex (2–3 mmm.), cell-contents granular, tinted cinnamon; pedicel persistent, hyaline, fragile, up to 25 × 5 mmm.; germ-pores indistinct. Host: Anisotome latifolia Hook. f. (= Ligusticum latifolium Hook. f.). On leaves. Herb. No. 41. Campbell Islands, T. Kirk! 1890. (Type collection.) Distribution: Campbell Islands. The host is endemic, and confined to the Campbell and Auckland Islands. (Cheeseman, 1906, p. 215.) This species is characterized by the almost smooth thick and hyaline epispore. This may prove to be a species of Uromyces, but this can be verified only by germinating the spores, and as the material at hand is too old (all attempts to germinate the spores having failed) it is retained here for the present.
