Lycopcrsicum and the grafted specimens grew more rapidly and luxuri- 

 antly than ungrafted specimens. The author has observed the same with 

 Physalis grafted on the Potato, Arabis albida on species of Brassica, 

 and Solanum auriculatum on S. tuberosum. Certain plants, he maintains, 

 can be more rapidly obtained and more beautiful and luxuriant specimens 

 procured by grafting them from seeds or ordinary cuttings. 



The "Wallflower was grafted on Red Cabbage, Abutilon Thompsoni on 

 Althcea narbonensis, Abutilon Thompsoni on Sida Napcea, and Petunia 

 hybrida on Nicotiana glauca. — J". P. 



Grafts, Heterogeneous. By Raymond Roger (Bev. Hort. pp. 166, 

 167 ; April 1, 1902). — A number of grafts between quite different orders 

 are quoted, e.g. Haricot Bean on Ricinus, Sunflower on Melon, Cabbage 

 on Tomato, Potato (Topinanibour) on Cherry, Chrysanthemum on 

 Tomato, Coleus on Achyranthus, Aster on Phlox, Cineraria maritima on 

 Tomato, Coleus on Tomato, Maple on Ash, &c, in all of which the 

 junction was sound and durable. M. Daniel, the authority for these, 

 considers the generic affinities to be of less importance than analogous 

 size, vigour, and vegetative habits or anatomical character, analogy of 

 tissue, and similarity of alimentary needs. The possibility is suggested 

 of such grafts affecting the seed of stock and scion, and thus leading 

 to unexpected variations. — C. T. D. 



Grafting* Monocotyledons. By Raymond Roger (Bev. Hort. 

 pp. 37-3S ; January 16, 1902). — M. Lucien Daniel has succeeded in 

 grafting on Vanilla and Philodendron. Success depends upon the extent 

 of contact surface, which must be large and obtained by very oblique 

 severance. — C. T. D. 



Grape-growing for Everybody. By E. A. Riehl (U.S.A. Hort. 

 Soc. Illinois, 1901, pp. 136-142). — The author in his short article treats 

 the subject from a popular point of view, and wishes every one to try 

 Grape-growing. He advocates the planting of young and thrifty vines 

 not over one year old, and says they should be cut down to the ground first 

 season, half the wood being cut away second season. Spraying with 

 Bordeaux mixture and autumn pruning is also described. — T r . 31. 



Grape Fruit Rots. By Henry Tryon (Qu. Agr. Journ. x. pp. 211- • 

 211 ; two plates ; March 1902).— The Dematium fungus rot is attributed 

 to the attacks of Exobasidium vitis or Dematium pullulans. This 

 disease differs from sun-scald in the fact that the berries are never 

 fissured, their contents shrinking instead of increasing in volume. It 

 may occur on any part of an affected bunch, and not on its exposed face 

 only. The diseased berries contrast with those surrounding them, which 

 remain green and intact, by exhibiting a reddish-brown coloration, with 

 the surface puckered with conspicuous folds, indicating a shrinkage of 

 their contents. The berries longest affected become of a deep chocolate 

 hue. At the same time the main axis and branches constituting the 

 bunch become brown or shrunken. 



This disease was first described in Australia by D. Mc Alpine in 1896, 

 and then called by him " Aureo-grape rot" — and attributed to Aurco-
