2. Variegation in Antirrhinums. The seeds were saved from 9 capsules of 

 seed of an Antirrhinum with ' striped ' flowers. The seeds were thoroughly 

 mixed together before sowing. 



753 seedlings were raised with the following results : White- flowered, 490 ; 

 Red-flowered, 198 ; Striped, 65. 



These were j udged by the appearance of the cotyledons and the first two or 

 three pairs of true leaves. 



The back of the cotyledons and leaves in the case of white varieties was green, 

 in the case of red varieties was more or less red in colour, and in the case of striped 

 varieties, was green marked with reddish stripes and dots. 



The number of striped varieties may be slightly larger, as some of the blooms 

 of white varieties are only slightly speckled with red, and the marking on the 

 leaves was indistinguishable. 



Further investigation shows that the stems of the older plants of ' striped ' 

 varieties are ' striped ' with red colour. The sepals and seed capsules are spotted 

 with reddish marks ; but, as a rule, the leaves do not retain their early distinc- 

 tiveness. 



Some of the ' red ' varieties have self-red blooms, while others have a white 

 tube to the corolla. The proportion of plain red to red-and-white has not been 

 determined. It is probable that the original plant was cross-fertilized by insects 

 with white, red, and red-and-white Antirrhinums growing near. 



Further experiments with regard to the inheritance of variegation of this 

 kind in Antirrhinums has been tried with segregated plants this summer. 



3. Variegation in Sweet Peas. This occurs occasionally and is heritable. 

 A plant raised from an old variety — ' Duchess of Westminster ' — had yellow 



leaves. This was very delicate and *only produced 1 pod of 3 seeds. All the 

 plants from these seeds were also yellow-leaved, but still more delicate than the 

 Fj generation. Only one plant flowered and 7 seeds were saved, of which 4 

 germinated ; 3 of the resulting plants had yellow leaves, and the fourth had varie- 

 gated leaves. All died without producing seed. 



Pelargoniums — Leaf variation under hybridization. 



1. 'Cataract' F v — Leaf resembles Radula (P. Radula X P. denticulatum) ; 

 'Cataract' X denticulatum F a . — Leaves intermediate, but nearer Radula; 

 ('Cataract' X denticulatum) X denticulatum F 3 . — One resembles Radula, one 

 resembles denticulatum. 



2. Denticulatum X filicifolium — F v — Leaves resembled denticulatum. 

 Do. selfed. — F, 3 ; Sections A, B, C. 



A resembled denticulatum, B were intermediate, C resembled filicifolium. 



(Set A resemble denticulatum, some even coarser cut. 

 F g j Set B all intermediate, but nearer denticulatum. 



(Set C, seven nearer filicifolium, one resembles denticulatum. 

 A unanimous vote of thanks was accorded to Mr. Smith for his exhibit. 



Seedlings of Victoria Plum. — Mr. M. B. Crane, on behalf of the John Innes 

 Horticultural Institution, showed coloured drawings of a long series of fruits and 

 seedlings raised from selfed flowers of the Plum ' Victoria.' The variation in 

 the size, colour, and form of the fruit was extraordinary, some being as small 

 as bullace and deep purple, others yellow and as large almost as ' Victoria.' 

 The variation in the form of the foliage was equally great. In some seedlings 

 the bark was smooth, and in others much split. Some of the seedlings are self- 

 fertile, others self-sterile. The Plum Victoria is thus apparently heterozygous 

 for almost all characters. The Committee, to mark their appreciation of the 

 excellence of the illustrative pictures, unanimously recommended the award of 

 a Certificate of Appreciation to Mr. C. H. Osterstock, Enderley, Watery Lane, 

 Merton Park, S.W.
