hitherto known it. He considers P. dispersa to be commoner in 

 warmer climates, and considers its profusion this year to be due 

 to the greater heat and dryness of the earlier part of the year. 

 He has proved by experimental culture that the secidiospores of 

 P. disperse/, occur on Anchusa vulgaris, but the life history of 

 P. glumarum, as far as this stage is concerned, is at present 

 unknown. The three fungi above referred to — Puccinia graminis, 

 P. glumarum, and P. dispersa — may, as has been suggested, be 

 popularly and appropriately designated the black rust, the yellow 

 rust, and the brown rust." 



Blenheim Apple Sport. — Mr. Wootton, of Byford, Hereford, 

 sent an Apple two- thirds of the surface of which was dark 

 crimson, the remaining part uncoloured, the junction between 

 the colours being sharply denned. The colour was confined to 

 the epidermis alone. It was thought that it might have been 

 crossed with the pollen of some dark-skinned variety ; but Mr. 

 Wootton reports that the neighbouring apple trees are a Eibston 

 and a King of the Pippins ; but several stocks of bees are very 

 near. A similar apple appeared on the same tree in 1895.

Primula sinensis and Hybrid. — Mr. E. Hyde, of Ealing, ex- 

 hibited at the meeting held on November 24 three fine plants of 

 an improved form of P. sinensis, raised from an originally wild 

 plant. They closely resembled drawings of this species when 

 first introduced about 1820. A botanical certificate was unani- 

 mously awarded to Mr. Hyde for them. He also showed a hybrid 

 raised between this species (male) and P. obconica (female), in 

 which the form of the umbel, as well as that of the leaf, more 

 resembled those of P. obconica. The segments of the petals 

 were flat and not reflexed, and but slightly cusped. These 

 differences, however, were not considered to be sufficiently pro- 

 nounced to be regarded as well-defined intermediate characters,, 

 so that it was apparently a case of prepotency on the part
