as the consequence of a rapid rise may 

 be a casting of the fruit. During the 

 progress of shooting great care must he 

 taken against sudden variations of the 

 temperature, water very sparingly used, 

 and every check, by fumigation, be 

 given to the various insects, which will 

 be particularly active at this period. 



" When the fruit is safely stoned, a 

 moderate dressing of rotten manure 

 may be spread on the surface of the 

 mould, the heat increased to CS*^, and 

 a more liberal supply of water given. 



" After the fruit has obtained a full 



house evergreen shrub. Young cut- 

 tings. Loam and peat. 



PODOSPERMUM. Nine species. 

 Hardy herbaceous, biennial, and an- 

 nual. The first is increased by divi- 

 sion, and all by seed. Common soil. 



PffiCILOCAMPA populi. December 

 Moth, is found in this month in orchards 

 sticking against the trunks of trees. 

 The wings are about an inch and a 

 quarter broad, and of a chestnut brown 

 in colour: on the upper pair there is a 

 pair of incurved bands, and a wavy one 

 near the centre ; the wings have also a 



size, and approaches maturity, air may grayish or brownish fringe. The lower 

 be freely admitted, and water should i pair are brown. The caterpillar is 

 be given in less quantities, and finally ! ashy gray at the sides, and rather dark- 

 discontinued a few days before gather- j er on the back, and it has four red 



ing." — Enc. Gard. 



PLUMBAGO. Eleven species. 

 Some hardy herbaceous, others stove 

 and green-house evergreen shrubs and 

 climbers. P. capensis produces a good 

 effect when plunged or planted out on 

 a rich border during summer. P. rhom- 

 bifolia is a stove annual ; this is propa- 



spots on each segment ; at first these 

 caterpillars are gregarious, under a 

 silken tent, from which they issue at 

 night to feed, but after a little time they 

 become solitary. They feed on various 

 kinds of fruit trees in the early part of 

 the summer, and when full grown, they 

 spin a silken case in which they change 



gated by seed, the others by cuttings, I the pups. The December Moth is not 



and all in common soil 



PLUMIERIA. Twenty-two species. 

 Stove evergreen shrubs and trees. 

 Large cuttings, slightly dried. Sandy 

 ioam, and a little peat. 



POCOCKIA cretica. Hardy annual. 

 Seed. Common soil. 



PODALYRIA. Thirteen species. 

 Green-house evergreen shrubs, Cut- 

 tmgs. Sandy loam and peat. 



PODANTHE. Seven species. Stove 

 evergreen shrubs. Cuttings in spring, 

 slightly dried. Sandy loam and lime 

 rubbish. 



PODANTHUS mitiqui. Hardy ever- 

 green shrub. Cuttings. Loam and peat. 



POD-FERN. Ellobocarpus. 



POD CARPUS. Eleven spe- 

 cies. Green-house and stove evergreen 

 trees. P. chinensis, P.macrophyllus, P. 

 nurifer, and P. verticillatus, are quite 



one of the most injurious to fruit trees, 

 but still, in localities where it is found 

 in tolerable abundance, the caterpillars 

 do considerable damage to the leaves. 

 Hand picking when the caterpillars are 

 living in society, is the best means of 

 diminishing them. — Gard. Chron. 



POET'S CASSIA. Osyris. 



POGONIA. Three species. Hardy 

 orchids. Offsets. Sandy peat.

 tings. Rich sandy loam.

 evergreen shrubs. Seed and cuttings. 

 Rich light soil. 



POINSETTIA. Two species. Stove 

 evergreen shrubs. Cuttings of previ- 

 ous year's shoots, slightly dried. Rich 

 sandy loam. Of these plants the most 

 beautiful is P. pulcherrina. On the 



hardy, if grown in a light-soiled border, cultivation of this we have the foUow- 

 sheltered from the north and east, and ing directions from Mr. W. Tillery, the 



well drained. Cuttings 

 and a little peat. 



PODOLEPIS. Five species. Hardy 

 herbaceous. Seed and division. Sandy 

 loam and peat. 



PODOLOBIUM. Five species. 

 Green-house evergreen shrubs. P. 

 scandens is a climber. Young cuttings. 

 Sandv loam and peat. 



Light loam, , gardener at Welbeck ; 



" Raise the plants from single eyes, 

 (like vines,) from the hard ripened wood 

 of last year, and re-pot them in sandy 

 loam and leaf-mould ; keeping them in 

 a cucumber-frame, and then in a low 

 stove, as near the glass as possible. 

 They do pretty near the glass and not 

 drawn, and then put into the stove in
