0, I. Unknown.
II. Uredosori amphigenous, seated on small angular yellow spots, orbicular, 0.5-1 mm. diam., orange-yellow, pulverulent, pulvinate, surrounded by the ruptured epidermis. Spores elliptical, obovate, or subglobose, 20-31 X 14-18 mium; epispore hyaline, closely, coarsely and unequally echinulate, spines sparsely distributed towards base of spore, 1.5 mmm. thick, cell-contents granular, orange; germ-pores indistinct.

The host is endemic, and is abundant throughout. (Cheeseman, 1906, p. 186.)
This rust is common in certain parts of New Zealand, and is conspicuous owing to the bright orange colour of the uredosori; in certain specimens the entire leaf-surface may be covered with the sori.
The uredo stage alone is known; the uredospores do not closely resemble other species of the genus, differing particularly in being echinulate and not covered with deciduous tubercules.
