Ivi PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



Calathea Allouya Tubers. — Mr. Morris stated that the tubers 

 exhibited by him at a meeting in June 1891, and supposed to be 

 of a species of Ksempferia, now proved to be derived from the 

 above-named plant, an old Carib food plant. The description 

 and chemical constitution ascertained by Prof. Church will be 

 found in Journ.Boy. Hort. Soc., vol. xiii. 1891, pp. lix. and cviii. 



Conifers. — Dr. Masters exhibited a branch of Pinus Pinaster 

 with erect cones instead of their being reversed. He mentioned 

 that he had once noticed a similar occurrence in the Scotch Fir 

 at Zermatt, Switzerland. The former had been described as 

 a new species with the name Lemoniana ; but it merely 

 represented a retention of the youngest condition of the cone. 

 P. ponderosa. — He showed cones of this tree, which are pecu- 

 liar in having the scales deciduous from below upwards, as 

 occurs in Abies. Pinus excelsa. — He also exhibited a branching 

 cone of this tree. 



Pyrus japonica Fruit. — Mr. Bead sent Apple-like fruits of 

 this plant remarkable for their large size, being 7 inches in 

 circumference and in height, and very symmetrical in form. 

 They were grown against a sunny wall in Ealing. 



The " Glassiness" Apple. — A specimen of this translucent 

 Apple was sent from Naples by Signor Piperno, where it is 

 considered one of the best eating Apples in Italy. Prof. Ward 

 examined and described it on a previous occasion. {Journ. Boy, 

 Hort. Soc, vol. xii., 1890, p. clxvi.)

 Committee, having devoted considerable attention to the effects of 

 London fogs on cultivated plants, is of opinion that the increasing 

 prevalence of these fogs is causing great inconvenience and loss
