Excluded or Doubtful Species. 



was found to agree with P. ludwigii Tepper. P. acetosae and its synonym, 

 P. rumicis Lasch. are therefore excluded. 



4. Puccinia aegra Grove. P. depauperans (Vize) Syd. The rust 011 

 the native violets ( Viola hederacea and V. betonicifolia) is comparatively 

 common, and has been collected at various localities in Victoria, New South 

 Wales, and Tasmania. It was at first determined by Winter as this species, 

 and Cooke has also recorded it, but the examination of numerous specimens, 

 including part of the same material forwarded to Dr. Cooke, showed the 

 teleutospores to be warted, not smooth, and aecidiospores likewise finely 

 vvarted, and therefore not this species. 



5. Puccinia apii Desm. The rust found on Celery, both native and 

 imported, in Australia, is found to be quite distinct from this species. 



6. Puccinia caulincola Corda is given by Cooke on Hypochoeris glabra, 

 but the species on this host-plant is undoubtedly P. hypochoeridis Oud. 



7. Puccinia geranii Corda was the name given by Cooke to the rust 

 occurring on Pelargonium australe, but it is now found to be a different 

 species, P. morrisoni McAlp. 



8. Puccinia investita Schw. was determined by Dr. Morrison on 

 species of Gnaphalium, but on investigating the original material I found it 

 to be P, gnaphalii (Speg.) P. Henc. 



9. Puccinia microseris McAlp. Since the host-plant of this species 

 was really Hypochoeris radicata it is now excluded. 



10. Puccinia phragmitis (Schum.) Koern. This species has not yet 

 been found in Australia, only P. maynusiana Koern and }'. tepperi Ludw. 



11. Puccinia rimosa (Link.) Wint. This species is given by Winter 2 

 as occurring on Isolepis nodosa R. ~Br.Scirpus nodosus Rottb. in Victoria, 

 but an examination of the original material only shows uredospores which 

 do not agree with those of this species, and Sydow * has arrived at the same 

 conclusion. The local specimen I have named Uredo scirpi-nodosi. 



12. Puccinia violae (Schum.) DC. This species is also given by Cooke 

 as occurring on violets in Victoria, but the history of the specimens shows 

 how necessary it is to guard against recording species as Australian which 

 may have been imported in the dry condition. The original material, with 

 the name in Cooke's handwriting, is accompanied by the following note 

 from the collector, Mr. Reader : " On leaves of what appears to be Viola 

 sp. found in an old book." I was so convinced, however, that P. violae did 

 not occur on our native violets, and had not been found growing on culti- 

 vated species, that I communicated with the collector, who informed me 

 that the leaves on which this species was found had been brought from 

 Europe and forwarded with other specimens for determination to Dr. 

 Cooke. Unfortunately, on the strength of this determination, Mr. Tryon, in 

 Queensland, and others, have also credited Australia with this species. Mr. 

 Reader, who is a chemist, also sent myself some jaborandi leaves 

 (Pilocarpus pennatifolius, Lem.) with a rust upon them, and it was found 

 to be Puccinia pilocarpi Cooke, but of course it had been imported. 



13. Cronartium asclepiadeum (Willd.) Fries. This widely distributed 

 species is recorded on a leguminous plant from Queensland, and the name is 

 given in Berkeley's handwriting on the specimen in the National Herbarium. 

 Dietel, however, regards it as a new species, and has named it C. jacksoniae. 



14. Melampsora nesodaphnes B. and Br. This species was found on 

 the fruit of Beilschmiedia (Nesodaphne] obtusifolia Benth., sent by Bailey to 

 Berkeley from Queensland, and I also found it on the fruit of Cinnamomum 

 oliveri Bail., sent by Baker from New South Wales. There is a mass of 

 powdery spores on the surface of the fruit which h swollen and distorted.
