I. -NOTES ON THE PLANTS OF SAN NICOLAS ISLAND. 



The plants upon which this report is based were collected 

 in April, 1897, by Mrs. Blanche Trask. It is the first col- 

 lection from this island of which any record has been 

 made, and like all insular floras possesses peculiar interest. 



Among the eighty or more species, nine are described as 

 new species, three as new varieties. There are besides six 

 insular types, though almost all the species are well repre- 

 sented on the other islands of the Archipelago as well as on 

 the mainland. At least fifteen have been introduced, being 

 plants of wide distribution and generally recognized as 

 weeds. It is somewhat surprising to find Rumex acetosella. 

 Polygonum aviculare, and Erigeron Canadensis absent 

 from the list. 



Under each species is given its distribution on the other 

 islands, this information having been obtained from the 



[ 89 ] Sept. 5, 1898.
