PucciNiA ERECHTiTES, McAlp. Oil leav€s and steins of 

 'Ereclitites quadridentata, DC. Between Coromandel Valley 

 and Clarendon, Sept. 23, 1916, T. G. B. O. I. and III. inter- 

 mixed, mostly on the- leaves. A number of three-celled 

 teleutospores are present in this specimen. Also Eden Hills, 

 Oct., 1917, Miss A. H. Rennie. I., numerous on stems, 

 present also on leaves and involucre; III., rare. 



On Ereclitites prenanthoides, DC. Blue Lake, Mount 

 Gambier, Oct. 12, 1916, A. G. Edquist. I. only, in groups 

 on both surfaces of leaves (McAlp., 1906, p. 157). 



Puccini A vittadiniae, McAlp. On living leaves of 

 Vittadinia australis, A. Rich. Wirrega R.S., Oct. 1, 1916, 

 T. G. B. O. I., III., and X. on both surfaces of leaves. As 

 recorded by McAlpine, the teleutosori were sparsely devel- 

 oped; occasionally four or five were observed confluent and 

 forming a ring about 2 mm. diameter round aecidia (McAlp., 

 1906, p. 164). 



PucciNiA OPERCULARIAE, (Morr.) Syd. 

 Teleutosori confluent, 3-5 mm. long, forming patches com- 

 pletely investing the stem; sori elongate, compact, buUate, 

 reddish-brownish, surrounded by the ruptured epidermis. 



Teleutospores golden-brown, oblong to clavate, slightly 

 -constricted at the septum, smooth, 45-52 x 15-18 /x. Upper 

 cell rounded, apex thickened, hyaline cap (7-9 /x) disappearing 

 when germinating. Lower cell about as long as the upper, 

 tapering to pedicel ; pedicel persistent, 22-50 /x long, 3-4 ju, 

 broad. 



Mesospores occasional, similarly coloured to teleutospores, 

 fusiform to ovoid, apex thickened with prominent hyaline cap, 

 38-45 X 14-18 jut. 



On stems of Opercularia varia^ Hook f.. III. and X., 

 Mount Compass, Oct., 1916, T. G. B. O. (fig. 3). 



This fungus was only found on the stems, where the patches 

 of telia formed prominent fusiform swellings, often in the 

 middle of the long internodes of the host. The species is a, 

 Lepto form, the majority of the spores being found with the 

 promycelia, or already empty. We have referred the rust to 

 • P. operculariae, (Morr.) Syd., though it may be that Morrison 

 was right in considering this a variety of P. coprosmae, Cooke. 

 Groups of confluent teleutosori on the leaves are a feature of 

 the latter species ; this feature is not noted by McAlpine for 

 P. operculariae, nor are mesospores which occur in our speci- 

 mens (McAlp., 1906, p. 166). 



PucciNiA HiBBERTiAE, McAlp. Teleutosori on stems, 

 leaves (amphigenous), pedicels, and calyces, causing hyper- 

 trophy of stem, densely gregarious, confluent. At first covered
