Cult. All the species of Philadelphus or Syringa are very

 of many of the species sweet-scented. They grow in any com- 

 mon soil ; and are readily increased by laying down the branches.

 valveless, 7-10-celled, opening irregularly near the prominent 

 nerves of the calyx. Seeds numerous, oblong, inclosed in a 

 membranous aril, fixed obliquely by their centre. Sarmentose 

 shrubs. Leaves opposite, glabrous, entire or toothed at the 

 apex, dotless. Flowers white, sweet-scented, disposed in ter-

Barbarous or Climbing Decumaria. Fl. July, Aug. Clt. 1785. 

 Shrub sarmentose or cl. 



Cult. Decumaria is a very proper shrub for training against 

 a wall or on trellis work, to form bowers, for which it is well 

 adapted from its sweet-scented flowers. It thrives well in any 

 common soil, and is easily increased by laying down the branches 

 or by cuttings.
