Aristolochia Goldieana. — Mr. Morris commented upon the 

 singular flower of this plant, which had blossomed at Kew, 

 and now exhibited. There had been a race between the flower- 

 bud and the shoot-bud. The former was small, and proceeded 

 out of the old wood. The flower-bud finally prevailed, and the 

 shoot was thereby checked. It is a West African species, dif- 

 fering from the South American in having twenty-four stamens, 

 &c. It is figured and described in the Botanical Magazine, 

 No. 5672. 



Primrose variety. — Mr. Wilson exhibited a seedling from 

 " Scott Wilson," of a deep blue-purple, with a red eye. 



J?lant Diseases. — Rev. C. Wolley-Dod gave an interesting 

 account of several diseases of plants in his garden, and com- 

 mented on the difficulty of finding curative means, or of hearing 

 of other suggestions than burning. He first alluded to a species 

 of smut (Ustilago) on Primula farinosa, which appeared to be 

 indigenous, as the plants were collected in Lancashire ; and, 

 although it was grown with P. denticulata, the smut was con- 

 fined to the former species. iEcidium ficaria? had attacked his 

 Hellebores. In this case, a drier soil was suggested as likely to 

 prove effective in ridding the plants of the fungus. The "Lily 

 spot," due to Polyactis cana, usually appearing late in summer, 

 had been seen in April upon Tulips, and apparently the same 

 species on Daffodils. It was suggested that a mixture of sulphate 

 of copper and quicklime would prove effective, as in the case of 

 Vines, described below. Puccinia Schroeteri had occurred on 

 Daffodils from Portugal, and also upon the common double 

 sorts. 



Diseased Vines, Treatment of, in France, icith " Bouillie 

 Bordelaise." — Mr. Dod.read the following communication : — "In 

 the Medoc there are three applications of the treatment. (1) 

 The first is towards the end of May, when the Vine has produced 

 shoots about 30 centimetres long. At this period the flower of 

 the Vine is not yet opened. (2) A second application is made at 

 the end of J une or the beginning of July. (3) A third about the 

 first half of August. The first application requires about 2 hec- 

 tolitres of Bouillie per hectare. The other two, 2^ to 3 hectolitres 

 per hectare. With' regard to the preparation of the Bouillie, the 

 following is the jtoethod employed: — For 100 kilos. In one 

 tub is put 50 kilos, of water and 3 kilos, of sulphate of copper ; in
