The host is indigenous, and is widespread, occurring in marshy localities 
from sea-level to 1,000 m. ; it occurs also in Australia, Malay Archipelago, 
and temperate South America. (Cheeseman, 1906, p. 775.)

e 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.

П. Uredosori hypophyllous, seated on reddish-purple spots which are 
visible on the upper surface, scattered, elliptical, 1 mm. long, or confluent 
and up to 5mm. long, pulverulent, pallid brown, bullate, surrounded by 
the ruptured epidermis. Spores subglobose or broadly elliptical, 16-22 mmm. 
iam.; epispore hyaline, densely and finely echinulate, 1:5 mmm. thick, 
cell-contents granular, yellow ; germ-pores scattered, numerous (6-8), 
obscure.

The host is indigenous, and is widespread ; it occurs also in Norfolk 
Island and Polynesia. (Cheeseman, 1906, p. 715. 
Characterized by the small spores, densely and finely echinulate hyaline 
epispore, and numerous scattered, obscure germ-pores. 
Although this form does not agree in all particulars with the descri 
tion published by Dietel, it resembles it too closely to allow of its 
being separated as a distinct species. It agrees in most particulars with 
U. Dianellae Rac., so that this form is better classed as a synonym. 
6. Uredo Phormii n. form-sp. (Fig. 118.) 
II. Uredosori hypophyllous, seated on discoloured spots visible on the 
upper surface, scattered or more commonly crowded into irregular groups 
often covering the entire under-surface of the leaf, elliptical, 1 mm. long, 
or confluent and up to 6mm. long, ferruginous, bullate, pulverulent, 
surrounded and partially covered by the ruptured epidermis. Spores 
obovate, elliptical, or subglobose, 21-30 x 17-22 mmm. ; epispore golden- 
brown, coarsely and sparsely echinulate, 2-5-3 mmm. thick, cell-contents 
brown, granular ; germ-pores scattered, 3-5, commonly 3, conspicuous.
