PKU'NUS. Plum. (From prune, a 

 plum. Nat. ord., Ahruntdn-orts [Dru- 

 pacese]. Linn., 12-Icosandria l-M<to- 

 gj/nia.) 



Hardy deciduous trees, white-flowered, and 

 blooming in April. Seeds for varieties and 

 stocks, suckers for grafting and budding ; deep 

 loamy soil, if calcareous all the better. For 

 the cultivated Plum, the Muscle and St. Julian 

 stocks are generally used. When dwarfs are 

 desired, the Myrobalan Plum is preferred. To 

 obtain stocks in great plenty, the long shoots 

 from the stools of last year's growth are laid 

 down in the spring their full length, and co- 

 vered with soil ; almost every bud sends up a 

 shoot, and roots are formed nearly cotempora- 

 neously. In autumn, the shoot laid down is 

 cut off, and then cut into as many pieces as 

 there are young shoots and roots. See Plum.

PSEUDO-BULB. By this term is 

 described the fleshy stem of the or- 

 chids; and the term is applicable as 

 it resembles a bulb more than a 

 stem. 



PSI'DIUM. Guava. (The Greek name 

 once applied to the Pomegranate. Nat 

 ord., MyrtleUooms [Myrtacese]. Linn., 

 1'2-Icosandria 1-Monogynia. Allied to 

 Myrtus.) 



Stove, white-flowered, evergreens. Cuttings 

 of young shoots, getting a little firm at their 

 base, in sand, under a bell-glass, and in bottom 

 heat ; sandy fibry loam and peat, with the ad- 



PSO 



lition of leaf-mould, and a little dried cow-dung, 



rovided the drainage is good and plentiful. 

 Winter temp., 48 to 58; summer, 6() to 85. 

 But several, such as Cattleyanum, will not only 



ive, but produce their fruit in a greenhouse. 

 The best Guanas we have seen were produced 

 on the back of a vinery, from which the frost 

 was little more than excluded in winter. See 



Huava.

 Nat. ord., Leguminous Plants [Fa-

Herbaceous by division, as fresh growth 

 commences ; shrubs, by cuttings of the half- 

 ripened shoots, in April or May, in sand, under 

 a glass ; sandy peat, and sandy fibry loam. 

 Winter temp, for these, 40 to 48. Glandulosa 

 has stood in the open air for a number of years, 

 near London. There are some annuals and 

 biennials, but not worth cultivating.
