The different species of Wiste- 

 ria are not easily named except 

 when they are in .flower. The 

 most beautiful of them are the 

 Asiatic species, W. sinensis and 



W. floribunda, the latter especially extensively grown near 

 the coast; in the interior the native species, of which W. 

 macrostachys is one, succeed better, though they are far less 

 attractive. 



Wisteria, or Wistaria as it was intended to be written 

 and as it has passed into popular parlance, was named in 

 honor of Dr. Caspar Wistar, one of a number of American 

 physicians forming the subject of a little volume on some 

 American medical botanists commemorated in our botanical 

 nomenclature, published in Troy by Dr. Howard A. Kelley in 

 1914. 

 Stems somewhat retrorsely hairy. W. macrostachys.
