X kewensis (stated to be a piece of the original plant) and P.floribunda. 

 The ovules of the P. x kewensis plant used appear to be infertile, 

 but the pollen is fertile with P. florihunda (apparently not with P. x 

 kewensis and P. verticillafa) . The plants shown exhibited white, 

 sulphur, lemon and other shades of yellow, and one had deeper yellow 

 flowers than x kewensis. Variety was also seen in the size of leaf 

 and in degree of hairiness. The plant of kewensis used is the only 

 one that has given breaks of this nature. It belongs to the small- 

 flowered type, which has the normal number of chromosomes ; 

 not to the large-flowered type with double the normal number of 

 chromosomes. 



Seeds of Forest Trees. — Mr. H. J. Elwes, F.R.S., showed ripe seeds 

 of Aesculus indica sent to him by Lord Ducie, and ripened at Tort- 

 worth, together with seeds of Juglans nigra and of Butter-nut ripened 

 at the same place. He remarked upon the great length of radicle 

 produced by the seedlings of Juglans nigra, which he had raised, as 

 compared with the mass of fibrous roots produced near the surface 

 by the Butter-nut, although the trees apparently grew under the 

 same conditions in nature. He thought it very desirable that com- 

 parison should be made with the behaviour of seedlings raised in 

 other places, and from seeds of American origin. 



Hedychium Greenii producing apical bulb.— Re also showed a stem 

 of the Scitamineous plant, Hedychium Greenii, which he had collected 

 in Bhutan, and which had flowered with him at Colesborne. He had 

 removed the flower shoot and the plant had produced a bulb at the 

 apex of the stem left. 



Mr. Elwes also showed flowers of Alstroemeria Hookeri and Tricyrtis 

 stolonifera. 



Frost damage to Apple. — Mr. F. J. Chittenden showed an apple 

 with ten longitudinal grooves of about a quarter inch depth on the 

 outside, the grooves being lined with russet. He called attention 

 to the small fruits damaged internally by frost, which he exhibited 

 earlier in the year, and pointed out that the grooves corresponded 

 with the position of the primary vascular bundles which had been 

 injured by frost. These bundles in the specimen exhibited still 

 showed signs of the damage, and the failure to grow normally was 

 no doubt due to the interference in the sap flow brought about by 

 this injury. 



Apple in bird's-nest. — Mr. Wilson Fox, of Carmino, Falmouth, sent 

 a photograph showing an apple attached to the tree and resting in a 

 bird's-nest, apparently that of a redpoll.
