McAlp., Agr. Gaz. N.S.W., vol. 6, p. 854, 1895. 
ermogones amphigenous, aggregated, numerous, honey-coloured. 
I. Aecidia hypophyllous, crowded in irregular gro ups which are often 
linear. Peridia cylindrical, up to 0-5 mm. diam., margins ate lacerate, 
expanded. Spores globose, obovate, 27-39 x 22-25 mmm. ; epispore hyaline, 
minutely and densely verruculose, 2 mmm. thick, cell-contents vacuolate, 
orange yea 
„ Uredosori amphigenous, circular, scáttered, bullate, рти шеш, 
1-1: dud mm. diam., surrounded and partially covered by the. ru ruptured e 
dermis. Spores elliptical to obovate, 27—37 x 22-25 mmm. ; epispore pallid 
yellow, 3 mmm. thick, densely and coarsely echinulate, Ааа orange- 
yellow, with 4-5 scattered germ-pores on one face. 
III. Teleutosori amphigenous, arranged in circinnate groups, circles 
ining à diam. of 5 mm., or scattered when elliptical and up to 4n

II. York Bay (Wellington), E. H. Atkinson! 24 Jan., 1921. 
Distribution: Victoria ; Tasmania. 
The host is endemic, although Cheeseman (1906, p. 192) states that it 
is probably identical with the Australian T. im Hook. f 
characteristic feature of this species is the large size, and the greatly 
thickened epispore of the teleutospores. I am indebted Mr. C. €. 
Brittlebank for specimens of this rust for comparative purposes.
