Puccinia Digraphidis j Soppitt. — Mr. Soppitt's discovery that 

 the iEcidium on Lily-of-the-Valley is connected with a Puccinia 

 on Phalaris arundinacea is very interesting — the more so when 

 we remember that this grass is known to be the host plant of 

 several other Puccinise — viz., P. sessilis, which has its ascidio- 

 spores on Allium ursinum, P. Phalaridis— which has its aacidio* 

 spores on Arum, P. maculatum, and a form of P. coronata — the 

 life-history of which is at present uncertain. The Lily-of-the- 

 Valley on which I produced the iEcidium from P. Digraphidis 

 has been growing in my garden at King's Lynn since the year 

 1879, and has hitherto been free from any iEcidium ; but eight 

 days after the germinating aacidiospores of P. Digraphidis were 

 applied to it the Lily leaves began to show signs of the presence 

 of the parasite, which in due course developed into the perfect 

 iEcidium. This culture was done at the request of Mr. Soppitt, 

 in order that his discovery of the host plant bearing the teleuto- 

 sporesof the Lily-of-the-Valley iEcidium might be confirmed by an 

 independent observer. The iEcidium produced and the material 

 used for producing it are on the table. 



Uromyces maritima, Row. — The life-history of the iEcidium 

 on Glaux maritima was unknown until the present year. In 

 August last Mr. Peake, jun., of Hull, was kind enough to conduct 

 me to the only known British locality for this iEcidium — on the 

 banks of the Humber. From an examination of the surrounding 

 plants I came to the conclusion that the ^Ecidium on Glaux was 

 due to the Uromyces on Scirpus maritimus. A supply of the 

 Uromyces was collected, and this spring applied to Glaux mari- 

 tima in my garden at King's Lynn. In due course the aecidio- 

 spores were produced ; these in turn were applied to healthy plants 

 of Scirpus maritimus and the Uredo produced. The specimens 

 used in their culture are exhibited. 



Mci&ium on Black Currant Leaves. — This fungus was found 

 by my friend the Rev. Canon Du Port, on the Norfolk Broads, in 

 June 1890. Its life-history is at present unknown, although I 

 have visited the spot, and hope to be able to work it out from 

 material collected. Whether it be the same species that occurs on 

 the Gooseberry pretty commonly in various parts of the country 

 experimental research alone can determine.
