III. Teleutosori similar to the uredosori but dark chestnut-brown. 
Spores subclavate or broadly elliptical, 29-40 х 16-22 mmm. ; apex 
rounded, not thickened, base rounded, seldom subattenuate, both cells 
usually same size and colour, lower sometimes slightly narrower; slightl 
or not constricted at the septum ; epispore golden-brown, finely and sparsely 
verrucose, 1:5-2 mmm. thick; pedicel deciduous, hyaline, short, u to 
35 x 5mmm.; germ-pore of the upper cell apical, conspicuous, papillate, 
basal pore two-thirds below the septum, conspicuous, papillate. 
Host: Apium prostratum (DC.) Lab. On leaves and stems. Herb. 
No. 313. II. Seashore, Seatoun (Wellington), G. H. C. 10 Feb., 1921. 
Distribution: Australia; Tasmania. 
The host is indigenous, and occurs also in Australia, Tasmania, Ant- 
arctic America, and South Africa (Cheeseman, 1906, p. 205). 
Characterized by the non-thickened apex and warted epispore of the 
teleutospores, and the thickened apex of the uredospores. 
І am indebted to Mr. C. C. Brittlebank for material of this rust for 
comparative purposes. 
32. Puccinia Cockaynei n. sp. (Fig. 51.) Gentianaceae (15). 
0. Spermogones amphigenous, seated on yellow spots, mixed with or 
surrounding the uredosori, immersed, honey-coloured 
II. Uredosori amphigenous, chestnut-brown, circular to elliptical, minute, 
up to 1 mm. diam., scattered, pulverulent, bullate, surrounded by the 
ruptured epidermis. Spores subglobose, elliptical, or commonly obovate, 
20-32 x 17-26 mmm. ; epispore finely and sparsely echinulate, 2 mmm. 
thick, cinnamon-brown, with one conspicuous germ-pore on one face.

Both hosts are endemic, G. corymbifera being confined to the South 
Island (Cheeseman, 1906, pp. 448-49). The teleutospores are regular 1n 
Shape, and us remarkably uniform on the different collections from 
different localities
