Host: Hierochloe redolens (Forst. f.) R. Br. On leaves. Herb. No. 762. Sea-level, Bluff (Southland), W. D. Reid ! 26 May, 1922. (Type.)

II. Uredosori hypophyllous, seated on dark-coloured spots visible on the upper surface, linear, 1 mm. long, seldom confluent, pulverulent, orange-yellow, surrounded by the ruptured epidermis. Spores subglobose or obovate, 34-45 X 30-35 mmm.; epispore tinted yellow, finely and moderately echinulate, 2-2-5 m. thick, cell-contents yellow, granular; germ-pores scattered, numerous (8-12), obscure.

II. Soris uredosporiferis hypophyllis, in maculis fuscis, linearibus, raro confluentibus, pulverulentibus, 1 mm. longis, luteo-aurantiacis, rupta epidermide cinctis. Uredosporis subglobosis vel obovatis, 34-45 X 30-35 mmm.; episporio pallido-luteo, leniter subtiliter echinulato, 2-2.5 mmm. crasso, contentu luteo, granuloso; foraminibus germinis raris, numerosis (8-12), obscuris.

The host is indigenous, and is abundant in moist places throughout; it occurs also in Fuegia, Tasmania, and Victoria. (Cheeseman, 1906, p. 855.) This rust is characterized by the large size of the spores, thick, finely-echinulate epispore, and numerous scattered obscure germ-pores. Puccinia Hierochloae S. Ito, a species belonging to the P. coronata group on account of the coronate apex of the teleutospores, differs in the uredospore stage from that described above, the uredospores of this species being much smaller (16-27 X 12-18 mmm.). It was first described from Japan by Ito (1909).
