Persea, Gartner. A name applied by Tlieo- 

 phrastus to an Egyptian tree. Linn. 9, Or. 1, 

 Nat. Or. Lauraceos. This ornamental species 

 succeeds well in a mixture of turfy loam and 

 peat. The best way of propagating it is by 

 layers, which root freely ; ripened shoots taken 

 off at a joint, and planted in sand, under a 

 glass, in heat, will sometimes root. Syno- 

 nyme: 1, LaHrus Pirsca.

 Persica, Tournefort. So named from the 

 Peach-tree coming originally from Persia. 

 Linn. 12, Or. J, Nat. Or. Drupacece. To this 

 genus belong the well-known and much-es- 

 teemed fruits the Peach and Nectarine. The 

 different kinds are propagated by budding on 

 Damask plum-stocks, and new varieties are 

 raised from the stone, after a mixtui-e of the 

 sorts by impregnation. In this country, they 

 are usually trained on south walls in the fan 

 manner, which is allowed to be the most 

 natural. The soil best suited for them is 

 three-parts mellow-loam, enriched with one- 

 part vegetable mould. Synonymes: 1, Amfjg- 

 dalus Pirska Nectarina ; 2, A. Pirsica.

 ing from five to seven feet high, and thriving

Pesomeria, Thouars. Prom pipto, peso, to fall, 

 and mens, a part ; the sepals are spontaneously 

 thrown off from the flower shortly after they 

 have expanded, just as leaves are thrown olf

 receive a sudden check, and then the petals 

 and labellum only remain to constitute the 

 flower. Linn. 20, Or. 1, Nat. Or. Orchidacem. 

 The plant is nearly related to BUtia* and 

 Phaius, but will probably be found to grow 

 best under the treatment given to Burling- 

 tdnia.
