Amelanchier canadensis, the June-berry, Shad-bust), Grape 

 Pear, or Service-beny, of the United States, is a very 

 variable plant, especially in the form and size of the leaves, 

 their indumentum, the length of the racemes, and the form 

 of the calyx-lobes and of the petals. Torrey & Gray have 

 in the Flora of N. America made five varieties. Sereno 

 Watson, in his Bibliographical Index to N". Am. Botany, 

 has most carefully elaborated the synonymy of these, and 

 I have followed, with few exceptions, his synonymy of the 

 variety here figured, omitting a few references of no im- 

 portance. The species, under one or other form, ranges 

 over the whole of temperate N. America, from Florida to 



October 1st, 1898.
