similar to that of curled Parsley, or of some of the varieties of Scolo- 
pendriums. It was stated by the raisers that the subdivision of the leaves 
was observed originally on plants bearing flowers of the ordinary character, 
and subsequently on those which had fringed flowers. Continuous 
selection through some seven or eight years had at length resulted in the 
production of plants in which the foliage and the corolla were equally 
deeply fringed. 
Bose-Ieaves. — Some Rose-leaves were sent for an opinion. They had 
been grown under glass, and presented no appearance of insect or fungus, 
but were thin in substance, and partly destitute of chlorophyll, showing 
that the nutrition of the plants was impaired, but from what cause could 
not be ascertained. 
Vim-leaves diseased.— ^Yith reference to the samples sent to the last 
meeting from Gunnersbury, it was stated that in the opinion of Mr. 
Massee the appearances were consistent with the attacks of red-spider or 
punctures of aphides. The leaf-buds were observed by Mr. Massee to be 
infested with mites. 
Viburnum icitli Hypertrophied Branches. — A specimen vas sent by 
Mr. Richard Dean, who stated that the whole tree was covered, at 
intervals of a few inches, with globose, nodulated, somewhat fleshy 
excrescences the size of a large Cherry and upwards. It was referred to 
Dr. Wilham G. Smith for examination. 
Scientific Committee, April 10, 1900. 
Dr. M. T. Masters in the Chair, and six members present. 
Vine-leaves diseased. — \Yith reference to the samples brought to a 
previous meeting from Gunnersbury, Dr. Masters observed, from further 
examination, that they were certainly not attacked by red-spider, but 
possibly by mites. There was still some doubt as to the presence of the 
young condition of Gheosporium. 
Orange striped. — With reference to the Orange brought to a previous 
meeting. Dr. Bonavia writes further in regard to the criticism of his 
theory that the stripe did not correspond to a single carpel, but covered 
halves of two : — " If this be so, I think that fact would seem rather to 
strengthen my theory, for the law of phyllotaxis [alternation of whorls] 
would appear to require such a disposition. My view is that the peel 
and pulp with carpels are tico independent whorls, the former coalescing 
to form a protective covering, while the latter has its carpels separable." 
The difficulty in accepting this theory arises from the fact that there is 
no mark of separation, the spongy tissues being continuous from the 
ovary cells to the circumference, the latter being charged with oil glands. 
Secondly, if the superficial layer were ' foliar ' one would look for fibro- 
vascular cords running through it, whereas there are none. All that are 
present permeate the soft tissue. Lastly, if it were foliar it must re- 
present a whorl of stamens ; but where such a whole takes on a pistillate 
character, they form short horn-like processes around the base only, and 
not a uniform covering."
