honey or sugar, and which is sold at Peking under the name of Meih-Tsau 

 (honey Jujube). 



Gall on the Boot of the Logan Berry. — From Mr. Holland, Malvern, 

 a hard rounded gall was shown on the roots of this plant, which is a 

 hybrid between a Raspberry and a Blackberry. Mr. Saunders pointed 

 out its resemblance to the root-gall of the Raspberry, attributed to eel- 

 worms, but he has been unable to find any trace of eel- worm in the 

 specimen exhibited. 



Carnation Disease. — Dr. Cooke reported on various specimens 

 recently sent, which he said exhibited the ravages of a parasite new to 

 this country, and apparently before undescribed. It is of the kind known 

 in the United States by the general name of iinthracnose, and is in all 

 cases a destructive pest. The leaves are at first spotted with small purple 

 roundish spots. These gradually enlarge and become confluent and 

 indeterminate, and at length brownish in the centre. Meanwhile the 

 leaves become sickly, and commence to die off at the tips. The pustules 

 are not to be distinguished by the naked eye, and scarcely by the aid of a 

 lens. Cells beneath the cuticle supply the place of definite receptacles, 

 and in them a large number of elliptical hyaline sporules (ten to twelve 

 by five //) are produced, which escape through the fissured cuticle. At 

 length the cuticle about the orifice turns pallid, and appears as a pale dot 

 on the purple spots. No described species of Glwosporium has been 

 found which answers to this diagnosis, and hence I called it — 



Glceosporium Dianthi (Cooke). — Amphigenous spots at first small, 

 roundish, dark purple, then confluent and indeterminate, sometimes turn- 

 ing brown at the centre. Pustules indistinct to the naked eye, but finally 

 pale at the orifice. Sporules elliptical hyaline (ten to twelve by five fi). 

 No remedies have been tried, but it would be advisable to apply diluted 

 Bordeaux Mixture, so as to destroy the extruded sporules, and to pick oft* 

 as many of the diseased leaves as possible. 



Seed-vessels of Araujia sericifera (Physianthus albens). — Some follicles 

 of this plant were sent by Mr. Pentland, Ashwick Hall, Gloucestershire. 

 The plant is an Asclepiad, the fruits of which are illustrated in the 

 Gardeners' Chronicle, 1893, vol. xiv., p. 436. The plant from which these 

 specimens were taken bore scores of fruits, the result of fertilisation 

 through the medium of insects. 



Hazel Buds a ffected ivith Mites. — Mr. R. W. Dean sent specimens of 

 buds distorted in the same manner as the buds of the Black Currant. 

 The occurrence of these buds in the Hazel and Filbert was known long 

 before the appearance of the Currant Bud-mite. 



(Enanthe crocata poisonous to Cattle. — Mr. Holmes showed tubers of 

 this plant thrown up on the sides of a ditch, where they had been eaten 

 by cattle with fatal results, the symptoms being similar to those of 

 poisoning by strychnine. (Fig. 63 ) 



Seedling Ailanthus bearing Floicers. — Dr. Masters showed specimens 

 he had received from Mr. Dinter, German S.W. Africa, which were 

 interesting as bearing flowers, while the cotyledons were still attached, 

 and the whole plant was not more than 2 or 3 ins. in height. Dr. 

 Masters recalled a similar production of flowers on a small shoot 

 proceeding fiom a sucker of the same tree, and also the formation of
