Besides these three species, which are the common shrubby forms in 

 cultivation, there are a number found in the South which will doubtless 

 soon be tried and may prove desirable. The smallest of these is Robinia 



nana, which grows only to the height of a 

 foot or two with almost an unbranched 

 stem and purple flowers f inch long with 

 white markings.
