460 ARBORETUM ET FRUTICETUM BRITANNICUM. 



Seeds subulate, heaped at the angles of the cells ; each furnished with a loose 

 membranous aril. Albumen fleshy. Differs from Afyrtacege in the arillate 

 albuminous seed, and in the toothed dotless leaves. (Don's Mill.) 



Leaves simple, opposite, exstipulate, deciduous ; toothed, serrated, or 

 sometimes entire. Flowers large, white, showy. Shrubs, natives of Europe, 

 Asia, and America. Three genera are hardy in British gardens, which are 

 thus contradistinguished: 



PHILADE'LPHUS. Calyx 4 5-parted. Petals 4 5. Stamens 20 40. Styles 



45. Capsule 4 5-celled. 

 DEU'TZ/^. Calyx 5 6 cleft. Petals 5 6. Stamens 10 12. Filaments 



tricuspidate. Styles 3 4. Capsule 3 4-celled. 

 DECUMA'RIA. Calyx 71 0-toothed. Petals 7 10. Stamens 21 30. Style 



1. Capsule 7 10-ce!led.

PHILADE'LPHUS L. THE PHILADELPHIA, or MOCK ORANGE. 

 Lin. Syst. Icosandria Monogynia. 



Identification. Lin. Gen., No. 614. ; Dec. Prod., 3. p. 205. ; Don's Mill., 2. p. 807. 



Synonymes. Syringa Tourn. Inst, t. 389., not of Lin.; Philadelphia, Fr. ; Pfeifenstrauch (Pipe 



Shrub), Ger. ; Filadelpho, Ital. ; Pipe Privet, Gerard \ the Syringa of the gardens. 

 Derivation. Philadelphia is a name used by Athenasus for a tree which cannot now be identified : 



Bauhin applied it to this genus. Instead of the common trivial name Syringa, applied to this 



genus in gardens, as its English name, we have substituted its generic name, Philadelphus ; 



Syringa being the generic name of the lilac. 



Gen. Char. Calyx tube obovate, turbinate ; limb 4 5-parted. Petals 4 5. 

 Stamens 20 40, free, shorter than the petals. Styles 4 5, sometimes 

 connected, and sometimes more or less distinct. Stigmas 4 5, oblong or 

 linear, usually distinct, rarely joined. Capsule 4 5-celled, many-seeded. 

 Seeds scobiform, enclosed in a membranous arillus, which is fringed at one 

 end. (Don's Mill.) 



Leaves simple, opposite, exstipulate, deciduous ; oval, acuminate, serrated 

 or entire. Flowers white, usually sweet-scented, disposed in corymbose 

 cymes, or somewhat panicled on the extremities of the lateral shoots, rarely 

 axillary and bracteate. 



Deciduous shrubs, natives of Europe, North America, and Asia ; culti- 

 vated for their very showy white flowers ; most of which have a strong scent, 

 resembling, at a distance, that of orange flowers, but, when near, disagreeably 

 powerful. The species are in a state of utter confusion : there are probably 

 only three : one a native of the South of Europe, or possibly of some other 

 country ; one of North America ; and one, P. tomentosus, of Nepal. All 

 the kinds are of the easiest culture in any tolerably dry soil ; and they are all 

 propagated by layers, or by suckers or cuttings. 



i. Stems stiff and straight. Flowers in Racemes.
