Pachyphytum (Echeveria) bracteosum {Rer. Hart. Behje, 

 January 1901). — Ad. ^'an den Heede describes his method of multiplying 

 this plant. In June 1900 he had only five small plants. He cut them 

 down below the leaves, leaving the base in the ground to grow ; the leaves 

 were carefully cut oft* and the crown replaced in the soil. The leaves 

 were then placed in leaf-mould and sand, being buried to the depth of a 

 centimetre (f in.). In August young plantlets began to appear. In 

 September they were abundant, so that in November he had 200. In a 

 particular experiment one leaf was inserted by the la^e, a second by the 

 tip, and a third buried entirely, only a piece of the stem being exposed. 

 He found the two latter were the quickest in giving rise to young plants.

Panax Balfourii {Bcv. Hnrt. Beige, April 1901).— This plant 

 is described by M. Ch. Pynaert as of recent introduction, with an illustra- 

 tion, showing variegated foliage, valuable for garden ornamentation. The 

 leaves are dark green spotted with cream and bordered with pure wliite. 

 It is very compact in form. It was introduced from New Caledonia 

 by Messrs. Sander. — G. H,

Peach Leaf Curl, its Nature and Treatment. By Newton B. 



Pierce {U.S. Dep. Agric, Div. of Veg. Phy. and Path. ; 30 plates and 

 10 figures. Washington, 1900). — A valuable report extending to 204 

 pages and abundantly illustrated. The nature of the disease, the history 

 of its treatment by previous workers, and the plan of preventive spray 

 work conducted by the Department occupy the first four chapters. The 

 next two chapters deal with the influence of spraying upon the foliage 

 and fruit of the trees ; while chapters viii. and ix. give a full account of 

 the preparation, composition and general character of the spray used, and 

 methods of application. Chapter ii., in which the fungus causing the 

 disease {Exoasciis deformans) is fully described and illustrated, will be of 

 particular interest to botanists. — D. H. 



Pear, * New ' {BarUett x Winter Nclis) {Amer. Gard. xxii. 323,

 Mass., and exhibited before the East New York Hort. Soc. This pear

 large size, thin skin, free growing and bearing qualities of ' Bartlett '
