1. Uredo Crinitae n. form-sp. (Fig. 114.) - Gramineae. 
II. Uredosori amphigenous, seated on discoloured spots, scattered, 
. seldom confluent, elliptical Imm. long, reddish-orange, pulverulent, 
po 
mmm. thick, cell-contents orange-yellow, granular; germ-pores scattered, 
numerous (12-18), conspicuous; mixed with and partially surrounded by 
numerous hyaline, capitate paraphyses. 
Host: Dichelachne crinita (Forst. f) Hook. f. Оһ leaves. Herb. 
No. 760. Akaroa (Banks Peninsula), 300m., W. D. Reid! 16 Jan., 
1922. (Туре.) 
The host is indigenous and is widespread ; it occurs also in, Australia 
and Tasmania. (Cheeseman, 1906, p. 873.) 
This rust is readily distinguished from any other on the Gramineae 
by the large globose spores, thin hyaline finely-echinulate epispore, and 
numerous scattered, conspicuous germ-pores. 
2. Uredo karetu n. form-sp. (Fig. 115.)

ost: Hierochloe redolens (Forst. f.) R. Br. On leaves. Herb. No. 762.

T яу aed : : : 
occurs also in Fue asmania, and Vietoria. (Cheeseman, 1906, 55 
s rust is characterized by the large size of the spores, thick, finely- 
echinulate epispore, and numerous scattered obscure germ-pores. Гиссина 
Hierochloae $. 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.). 1t was first described from Japan by 
Ito (1909). 
3. Uredo toetoe n. form-sp. (Fig. 113.) 
numerous (7-12), conspicuous, papillate. 
Host: Arundo conspicua Forst. f. On leaves. Herb. No. 759, 
Hokianga (Auckland), E. B. Levy! 24 Feb., 1921. Sandhills, Levin 
(Wellington), 16 m., E. Н. Atkinson! G. H. С. 12 Oct., 1922. (Type.) 
The host is endemic, and is abundant throughout. (Cheeseman, 1906, 
. 893.) 
: The rust is characterized by the conspicuous reddish-brown sori, closely 
and finely echinulate epispore, and numerous scattered, conspicuous, 
papillate germ-pores.
