taken from the axils of the large leaves during early summer 

 push freely, so that they will have plenty of roots before 

 winter sets in. Root cuttings of B. cordata strike freely. 



Boebera. Composite. 



Increased by cuttings made of young, rather firm shoots, 

 and placed in sand, under a glass. 



Bcehmeria. Urticacece. 



Increased by divisions. 

 Boleum. 'Cruciferce. 



Propagated by seeds sown in a pot in spring, placed in a 

 frame or in the open border during summer. 



Boltonia. Compositce. 



Increased by divisions of the root in March. 

 Bomarea. Amaryllidece. 



Propagated by seeds, which may be sown in a warm house. 

 Also increased by careful division of the underground stem. 

 In making a division it is necessary to observe that the part 

 taken has some roots by which to live till new ones are 

 formed. 

 Bombax (Silk Cotton Tree). Malvaceae. 



Plants raised from seeds brought from their native habi-

 joint, and placed in sand under a bell-glass, in moist heat. 



Bonapartea. See Tillandsia. 

 Bonjeania. See Dorycnium. 

 Bonnaya. Scrophularinecc. 



The annual species by seeds, the others by divisions and 

 cuttings. 



Bonnetia. Ternstroemiacece. 



Increased by cuttings of firm, young shoots inserted in 

 sand, under a hand-glass, in a moderate heat. 



BoragO. Boraginece. 



Propagated by seeds sown from spring or autumn in any 

 good garden soil. Also by divisions in spring, or by striking 

 cuttings in a cold-frame. 



Borassus. Palmece.
