Collections Examined

Host: Scirpus inundatus Poir. On stems. Herb. Nos. 282, 325. Seashore (Wellington), E. H. Atkinson! 17 April, 1920; 27 Jan., 1921. Bog, Tiritea, Palmerston North (Wellington), 300 m., G. H. C. 4 March, 1921. Seashore, Bluff (Southland) W. D. Reid ! 26 May, 1922.

Description

II. Uredosori caulicolous, scattered or crowded, elliptical, up to 2 mm. long, cinnamon-brown, bullate, pulverulent, becoming exposed by the longitudinal fissuring of the epidermis. Spores elliptical, obovate, or subglobose, 25-35 X 20-25 mmm.; epispore tinted cinnamon-brown, coarsely and sparsely echinulate, 2-2.5 mmm. thick, cell-contents granular, cinnamon-brown; germ-pores equatorial, 2, conspicuous.

Distribution

Distribution: Victoria.

Notes

The host is indigenous, and is widespread, occurring in marshy localities from sea-level to 1,000m.; it occurs also in Australia, Malay Archipelago, and temperate South America. (Cheeseman, 1906, p. 775.)
The rust forms conspicuous bullate sori on the stems; these are usually severely infected with Darluca filum Cast. Characterized by the thick coloured epispore, and the two equatorial conspicuous germ-pores.

Pathogenicity

All host species [Scirpus spp.] are indigenous to New Zealand and occur throughout the country: the rust has been collected only in the Wellington and Nelson Provinces.
