of this species. He asked that others would make observations in order 

 to note whether this was a common phenomenon or not. 



Seakale disease. — Mr. Giissow showed a specimen of Seakale which 

 had become rotten, one of a considerable number in a plantation in 

 Norfolk, which he said had been attacked by a bacillus, at present 

 undescribed, differing in certain characters from Pseudomonas campestris. 

 He considered that the attack of the organism upon the Seakale had been 

 mady possible by the methods adopted in forcing it, and that the attack 

 might have been prevented if air had been admitted by raising the Seakale 

 pots somewhat above the soil level. 



Intumescence in Bruqmansia. — Mr. Saunders, F.L.S., showed a leaf 

 of Brugmansia exhibiting small warty growths, somewhat resembling 

 intumescences, a condition brought about usually by lack of a proper 

 balance between the amount of water supplied at the roots and the 

 humidity of the air, and a proper regulation of temperature. 



Amaryllis sp. — Mr. Elwes, F.R.S., showed a plant apparently allied 

 to Amaryllis solandracflorum, but having a rose suffusion upon the 

 perianth. The flowers are of very elegant form, and the plant appears 

 to be rarely seen in this country. 



Moraea iridioides var. Johnsonii. — Mrs. Richmond, Woodlands, 

 Lustleigh, South Devon, sent a flower and leaf of the very beautiful 

 variety Johnsonii of Moraea iridioides. The flowers are considerably 

 •larger than those of the type or the variety Macleayi, and the foliage 

 is upright instead of being fan-shaped ; the bud was picked on May 7, 

 and the flower was still almost perfect on the 12th inst. The seed from 

 which the plant originated was brought by a lady (Mrs. Johnson) from 

 the mountains of Ceylon, where it had probably been originally taken 

 from South Africa. 



Scientific Committee, June 9, 1908. 



Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the chair, and fourteen 

 members present. 



Brugmansia leaves injured.— My. Giissow reported that he had 

 examined the leaves of Brugmansia shown at the last meeting by Mr. 

 Saunders, and found that they had been injured by some insect which 

 had punctured the leaf, and around this puncture corky cells had 

 developed. 



Malformed Orchids. — Mr. Worsdell, F.L.S., reported that he had 

 examined a specimen of Cattleya intermedia referred to him, in which 

 three flowers had become fused together so that there were eighteen 

 perianth pieces in the resulting fasciated specimen and three properly 

 formed columns. The ovaries, however, were completely absent. Mr. 

 Gurney Wilson, Haywards Heath, sent flowers of Odontoglossum crispum 

 which were referred to Mr. Worsdell (see p. cxiii). 



Oxalis bupleurifolia. — Mr. Hales showed the interesting Oxalis 

 bupleurifolia, a Brazilian species with small yellow flowers, having the 

 petioles developed into phyllodes, which are remarkable in being placed 

 horizontally instead of vertically, as in most plants possessing phyllodes.
