Osier, Parasite Of (Le Jardin, vol. xxi. No. 479, p. 35 ; February 5, 

 1907). — Phyllodacta or Phratora vulgatissima. — A small coleopterous 

 insect, which feeds more particularly on yellow osiers. That red osiers, 

 as well as the variety known as 1 Grisette Jaime,' are far less liable to 

 the pest illustrates the fact of the varying resistance offered to the same 

 parasite by different varieties of one plant. — F. A. W.

Paeonies, Tree. — Classification, with coloured plate and 2 figs., by 

 Hortulus ; Culture, by P. Savreau (Le Jardin, vol. xxi. No. 485, p. 136 • 

 May 5, 1907). — Tree paeonies are best propagated by grafting on roots 

 of ordinary herbaceous paeony at the end of August. Choose the grafts 

 from shoots that flowered in the spring, leaving two to three eyes at the 

 base, and trim into a wedge from lowest eye to fit groove in root, which has 

 previously been sliced across horizontally, leaving 3 to 4 inches in length. 

 Pot the grafts in frame or bell-glass. Leave for a month in northerly 

 exposure with full light and air. Tree paeonies are easy to force. Select 

 plants that have been reared in pots with well-formed buds, bringing 

 them into a cool house, 15°-20° C. (60 c -68° Fahr.), in December or 

 January. In the open they require ^irotection in the spring. They should 

 be looked over each spring, cutting out the dead wood, lopping the bigger 

 branches, and thoroughly pruning what are left, leaving only a certain 

 number of flowering buds, and encouraging the lower eyes at the expense 

 of those borne on the old wood. — F. A. TF.
