divisions of the corolla; and Mr. Berkeley reminded the Com- 

 mittee of a similar condition which occurs occasionally in Colchi- 

 cum, and which is figured in 'English Botany.' Dr. Masters 

 alluded to a like phenomenon in the Lily of the Valley. 



Mr. Berkeley then produced a plant of Abiitilon Thompsoni 

 variegatum, from Messrs. Henderson, grafted on A. striatum, which 

 had variegated the stock both above and below the graft, a case 

 exactly analogous to the often quoted influence of the variegated 

 Jasmine on a self-coloured stock. Dr. Masters stated, on the 

 authority of Mr. Fortune, that A. striatum sometimes produced 

 variegated shoots. 



It was considered desirable that experiments should be made 

 at Chiswick. 



The Chairman produced a series of leaves of Cyclamen Euro- 

 pceiim from Corfu, showing every intermediate stage between 

 even-edged and hederaceous leaves. He considered it the same 

 with G. Africanum. Mr. Munby suggested it might be C. Jiede- 

 rcefolium ; but the question arises whether that is really different 

 from C. jEuropceum. 



Professor Westwood reported on the insects contained in Or- 

 chid buds which were exhibited at the previous Meeting. The 

 bud submitted to him contained two species of Hymenoptera of 

 the genus Eurytoma in the pupa state. An American entomolo- 

 gist, Dr. Thaddeus Harris, had found on wheat-ears one species of 

 the genus which he had never found parasitic ; and we have here 

 another species, if not two, with an exceptional habit, in a genus 

 formerly supposed to be entirely parasitic. 



Dr. Masters exhibited a plant of Misletoe with both male aud 

 female fructification, a circumstance which had not been observed 

 before in the Misletoe, though not uncommon in Lorantlius. It 

 was quite clear, on examination, that the exception was not due 

 to the germination of a male seed on a female plant. 



Major Clarke compared it with the well-known case of the 

 Hautbois Strawberry. 



Dr. Masters then gave the substance of a paper by Mr. Taylor 

 on grafting Potatoes, and its extraordinary effect in producing 

 new forms. The paper will appear in extenso in the ' Gardeners' 

 Chronicle.' 



Major Clarke directed attention to the variability of the Potato 

 under different circumstances, and thought that this might have 

 something to do with Mr. Taylor's experiment. The subject,
