Introduced Plants. The following list inclndcs n1l tlio i)laiits of the 
collection that could be considered as introduced. The first eighj seemed 1o 
make themselves perfectly at home among the sage-brush, but i here nrc ibrms 
of Chenopodium album which are iiiid(nibtedly indigenous. 'I'he rest were 
found only near old fields or fences or in actual cultivation, exceptinir the last 
four, which were collected on stream-banks in cafions near roads ti-avcled 
only by the teams of woodmen. Their introduction is perhaps questionablf^.

Resume of the Distribution and Range of Genera and Species. 
The plants of the collection have been grouped in the preceedin-- lists accord- 
ing to the localities in which they were actually found. The few oilier re- 
ported species also included are placed, wheiilh.' character ol"ihe liabilal was 
not actually known, where they would be most likely to fall. As n-anls llie 
range of the species, by which the li.<1s are subdivided, no more than ai)i)roxi- 
mate correctness is in many cases ])ossil)l<-. In ilic (^^ilal-.-uc tli.' ran-e ..f 
each species wdthin the United States and r>ritish Anicrica is irivni as accur- 
ately as it could be learned by refen-nce to published works aiul an examin- 
ation of the collections at hand. ]3ut 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 se])arated localities, 
and hence an arrangement that- should propose to give more than a very
