the smaller examples sent herewith. How or why they are produced is 

 not very evident. The corrugated portion of the bole on which they 

 grow is, however, much shaded by surrounding shrubs." 



Gladiolus. — Mr. Jenkins, Hampton Hill, sent a very long spike of a 

 crimson variety ; the height was 3 ft. 8 in. It was the growth 

 from a corm which had remained out of the ground and neglected from 

 October 1900 to June 1902, when it was planted. 



Passiflora, n. sp. — Dr. Masters showed a specimen which had been 

 accidentally introduced by Messrs. Charlesworth with a Cattleya Mossice ; 

 it had not yet been described or named, but a description will shortly be 

 published. The foliage is of a highly ornamental character. 



Bunt, n. sp. introduced. — Mr. Massee described the introduction into 

 England of a new species of this fungus as follows : " Twelve years ago 

 one of the cereal bunt fungi was sent from Patagonia and Bahia Blanca, 

 where it was stated to be very abundant. The host plants were Bromus 

 unioloides, H.B.K., and Festuca bromoides, L. As usual, the fungus 

 formed a black mass in the ovary of the host plant, and proved to be a 

 new species — Cintractia patagonica, Cooke and Massee. Quite recently a 

 traveller in these regions observed that Bromus unioloides was extensively 

 grown, mixed with Lucerne for fodder. Seed of the Bromus was brought 

 home and sown in Lincolnshire, and on producing fruit was observed to 

 be attacked by the Cintractia. The above illustrates one of the methods 

 by which injurious fungi are introduced from one country to another, 

 and unless great care be taken to stamp out the newcomer, it is just 

 possible that we may eventually have to add another cereal fungus-pest 

 to our already long list." 



Scientific Committee, Novembee 4, 1902. 

 Dr. M. T. Masters, F.R.S., in the Chair, and ten members present. 



Ergot, Prevalence of. — Mr. Hooper observed that this disease was 

 particularly abundant this season, and exhibited specimens on Cocksfoot 

 and Rye-grass. It generally is frequent in wet autumns. 



Apple-trees in Blossom. — Mr. Hooper also referred to the occurrence 

 of flowers on Apple-trees, a fact elsewhere noted and probably due to the 

 mildness of the weather. Dr. Masters observed that when such flowers 

 occurred on spurs, they were instances of precocious flowering. 



Tomatos and Bordeaux Mixture. — Mr. Hooper also called attention 

 to the advantages of using this fungicide on outdoor Tomatos, which 

 were shown, when left to themselves, to have completely failed ; but 

 those sprayed bore at least half a crop even in this unfavourable autumn.' 



Crocus, rare species. — Mr. Bowles showed a blossom of C. speciosus 

 var. Aitchisoni, which bore a fine pale-coloured flower ; the country 

 whence it was received was not known. 



Cypripedium Malformed. — Mr. Saunders showed a drawing of a 

 flower having the labellum erect and one additional petal. Dr. Masters 

 undertook to add further details. 



Apple-leaf Black Mould.— Dr. M. C. Cooke, V.M.H., reported as follows 

 upon the Apple-leaves submitted for examination : — " They were badly
