 secidia towards November or earlier ; at that time of the year the Daisy 

 plants are generally in a condition of vigorous, though slow, growth. 



There is a species of Vni-rinii I', distincta McAlp.) found on Bellis 

 perennis in Australia, but this bears secidia and teleutospores on the same 

 leaves ; there are no uredospores. Since the Daisy is not a native of that 

 country and is grown there from seed imported from England and 

 Germany, it would seem that the fungus is imported with the seed ; yet in 

 our country ami in Germany, the Daisy never bears teleutospores. The 

 teleutospores of the Australian species closely resemble those of J', obscura 

 on Luzula, and like them are often intermixed with numerous mesosporea ; 

 moreover, they often grow amongst and round the secidia, apparently 

 always from the same mycelium. (Jan it be that the European fungus has 

 been introduced with the seed and has adapted itself to an autoecious life ? 

 This, however, seems hardly probable, since Luzula campestris is found in 

 Australia, but the Puccinia which attacks it there (P. tenuispora McAlp.) 

 i- different from either of our European species.

Uredospores. Sori amphigenous, on irregular and confluent 

 reddish-brown or blackish- brown spots, scattered, oblong, long 

 covered by the epidermis, ferruginous ; spores oblong-ovate to 

 pyrifprm or clavate, irregular, smooth, rarely aculeolate at the 

 summit, rusty-yellow, 30 — 44x12 — 15 //,; epispore colourless, 

 thick, without germ-pores. 



Teleutospores. Sori similar, but soon naked, compact, 

 blackish-brown ; spores clavate, much thickened (10 — '25 fi) 

 above where they are rounded or rarely more or less obliquely 

 tapering, gently constricted, tapering gradually downwards, 

 smooth, brown, 44 — 80 x 16 — 24 //, ; pedicels hyaline, persistent, 

 about as long as the spore or shorter.
