Introduced Plants. The following list includes all the plants of the 

 collection that could be considered as introduced. The first eight seemed to 

 make themselves perfectly at home among the sage-brush, but there are forms 

 of Chenopodium album which are undoubtedly indigenous. The rest were 

 found only near old fields or fences or in actual cultivation, excepting the last 

 four, which were collected on stream-banks in canons near roads traveled 

 only by the teams of woodmen. Their introduction is perhaps questionable.

Resume of the Distribution and Range of Genera and Species. 

 The plants of the collection have been grouped in the preceeding lists accord- 

 ing to the localities in which they were actually found. The few other re- 

 ported species also included are placed, when the character of the habitat was 

 not actually known, where they would be most likely to fall. As regards the 

 range of the species, by which the lists are subdivided, no more than approxi- 

 mate correctness is in many cases possible. In the Catalogue the range of 

 each species within the United States and British America is given as accur- 

 ately as it could be learned by reference to published works and an examin- 

 ation of the collections at hand. But the recorded localities, of the older 

 collectors especially, are frequently more or less indefinite, many species 

 are little known or have been collected only from widely separated localitieSj 

 and hence an arrangement that should propose to give more than a very
