CunnincHamM.—The Uredinales, or Rust-fungi, of New Zealand. 673 
Distribution: Australia; North America; Europe; Asia; Africa. 
The aecidial stage has not been collected in New Zealand. The host 
is endemic and widely distributed (Cheeseman, 1906, p. 568). 
I am indebted to Dr. Grove for sie of this rust for comparative 
purposes. The mycelium of the aecidia is perennial. There are minor 
differences i ie our form and the European; these are not as great, 
however, as the differences between European and American specimens 
that I have in ae herbarium.

The host is endemic and confined to the mountain regions of both 
Islands (Cheeseman, 1906, p. 549). The spores germinate immediately on 
reaching maturity. This species is closely related to Puccinia apus Diet. 
et Neg., but differs chiefly in the hypophyllous sori, larger teleutospores, 
and persistent pedicels.
