1 The spines in the last four genera are often found laterally to a leaf or 

 fascicle of leaves. In the leaf axils there usually arise 1-3 buds. Fre- 

 quently one of these develops into a spine, sometimes the two lateral 

 develop as spines, in other cases one lateral bud develops as a spine and 

 the other as a branch bearing one, or a fascicle of leaves, when the original 

 subtending leaf falls the spine thus becomes lateral to a leaf or fascicle.
