nown. 
I. Aecidia caulicolous, crowded in longitudinal groups, seated on 
fusiform swellings up to 7cm. long, forming large fastigiate distortions, 
orange-yellow. Репаіа cupulate, shortly erumpent, standing above the 
surface 0-25 mm., 0-5 mm. diam., expanded and slightly revolute, becoming 
lacerate, finally eroded, tinted yellow. Spores polygonal or elliptical, 
27-32 x 18-21 mmm. ; epispore hyaline, densely and minutely verruculose, 
1 mmm. thick, cell-contents granular, lemon-yellow. 
Host: Edwardsia tetraptera (J. Miller) Oliver (= Sophora tetraptera 
J. Mill). On branches. Herb. No. 763. Brightwater (Nelson), 200 m., 
C. Nash! W. C. Hyde! G. Н. С. 18 May, 1922. (Type.) | 
The host is indigenous and widespread; it occurs also in Lord Howe 
Island, Easter Island, Juan Fernandez, and Chile. (Cheeseman, 1906, 
p. 123. 
This rust forms conspicuous “ witch's-brooms " on the host. A branch 
becomes infected near the tip, and further outward growth is prevented. 
In the vicinity of the infected area numerous short laterals are produced ; 
The mycelium is perennial and material may be collected from infected 
plants throughout the year. 
indebted to Mr. C. Nash and Mr. W. C. Hyde for assistance in 
procuring these specimens. 
4. Aecidium Milleri n. form-sp. (Text-fig. 105, and Plate 1, fig. 7.) 
: | Tiliaceae. 
. Unknown. 
I. Aecidia hypophyllous, in minute scattered groups. 3-6 in a group, 
seated on pallid spots visible on the upper surface, pallid orange. Peridia 
cupulate, erumpent, 0-25 mm. diam., margins erect, not expanded or revo- 
lute, minutely dentate, white. Spores subglobose or polygonal, 20-26 x 
17-23 mmm. ; epispore hyaline, minutely and densely verruculose, 1 mmm 
thick, cell-contents tinted yellow, vacuolate. 
Host: Aristotelia serrata (Forst.) Oliver (= A. racemosa (A. Cunn.) 
Hook. f). On leaves. Herb. No. 776. Pokaka (Waimarino County), 
800 m., D. Miller! 10 Feb., 1922. (Туре.) я 
The host is endemic, and is widely spread throughout the lowland 
forests. (Cheeseman, 1906, p. 83.) 
This species is named in honour of the collector, David Miller, Govern- 
ment Entomologist, Biological Laboratory, Wellington. 
e aecidia occur in small groups of 3-6, each group being somewhat 
angular, and about 1 mm. in diameter. 
5. Aecidium Myopori n. form-sp.  (Text-fig. 106, and Plate 1, fig. 11.) 
t Пийк: Myoporaceae. 
I. Aecidia caulicolous, truncicolous, petiolicolous, and on inflorescences 
and drupes, seated on inflated fusiform areas up to 15 ст. long, crowded 
in linear groups, orange. Peridia erumpent, cylindrical, standing above 
the surface about 4mm., 1mm. diam., margins slightly expanded but
