adventitious flower buds in the axils of the sepals with their parts greatly 

 aborted. Mr. Chittenden had sent him one showing similarly malformed 

 growths, but in that the adventitious flowers had become well developed, 

 although stamens were missing from some of them, and so on. Although 

 the buds were probably really axillary to the sepals, they had become 

 laterally displaced owing to lack of room, so that they stood between 

 the sepals. The whole presented the appearance of a large double flower. 



Hybrid Orchid. -Mr. James Douglas, V.M.H., showed an interesting 

 hybrid raised by crossing the hybrid Cymhidium ehurneum x Lowianum 

 with C. ehurneum. The resulting plant had (lowers closely approaching 

 C. ehurneum in appearance and colour, but showing traces of C. Lowianum, 

 particularly in the tinting of the column, the suffusion of yellow on the 

 labellum, and the form of the double crest which runs down the labellum. 



Asparagus Kale dying. — Mr. S. T. Wright sent specimens of asparagus 

 kale from Wisley which showed, on cutting sections across the stem, 

 lattice-like openings in the woody tissue. These had been destroyed by 

 the attacks of the bacterium Pseudomonas campestris, well known in 

 some parts of the Continent and in America. It is reported that the 

 spores may be carried with the seed, and the disease so propagated. 



Scientific Committee, Apkil 2, 1907. 



The late Dr. M. T. Masters, F.R.S., in the Chair, and twelve other 



members present. 



Botanical Certificates. — Dr. Masters reported on the plant shown by 

 Mr. Bennett-Poe at the last meeting under the name of Thihaudia sp. (?). 

 The plant proved to be a hitherto undescribed species of Agapetes, and 

 the name Agapetes speciosa had been given it. On the motion of Mr. 

 Bowles, seconded by Mr. Worsdell, a botanical certificate was recom- 

 mended to this plant by seven votes to one on the ground of its novelty 

 and botanical interest. 



Narcissus from Chili. — Mr. Worsley showed the flower of a variety of 

 N. Tazetta, the bulb of which he had received from Chili, to which 

 country it had evidently been introduced and had escaped. Mr. Elwes, 

 F.R.S., said that he had been struck by the large number of South 

 European plants which had found a congenial home in various parts of 

 South America. 



Hybrid Vallota and Hippeastrum. — Mr. H. J. Chapman showed a 

 plant which he stated to be raised from seed produced by Vallota purpurea 

 crossed with pollen from a purple-flowered Hippeastrum. The foliage 

 was only just beginning to develop, and was stated to be very similar to 

 the Vallota in appearance. The flowers were large and white with a 

 rather broad greenish median vein. About two hundred seedlings of this 

 cross had been raised, all of similar habits, and all but three bore scarlet 

 flowers ; the plant shown and two others, however, had white flowers. 

 Mr. Chapman promised to show the plant again when in full foliage. 

 The reverse cross did not result in the production of any seed. 



Pollen of Phaius Hybrids. — Mr. Chapman observed that when two 

 species of Phaius were crossed the pollen of the resulting plant was
