 peachy. Flowers red. Perhaps a species of Ccesatpinia. 



Pyramidal-fiowered Robinia. Tree. 



Cult. All the true species of Robinia are very handsome 

 when in flower, and are very proper plants for ornamental shrub-, 

 beries ; the taller species to be placed at the back, and the shorter 

 ones in front ; they are either propagated by layers or by graft- 

 ing the rarer on the commoner sorts, most commonly on the R. 

 pseudaccicia. Most of the species may be raised from seeds, 

 which in some kinds ripen in plenty. The stove and greenhouse 

 kinds, which are certainly very doubtful species of the genus, 

 should be treated in the same manner as the genus Sabinea.
