XXIII.-A LIST OF THE PLANTS OF THE PRIBILOF ISLANDS, BERING 

 SEA. WITH NOTES ON THEIR DISTRIBUTION. 



By James M. Macoun 

 Assistant Naturalist to the Geological Survey of Canada. 



This list is believed to include all the plants that have been found on the Pribilof 

 Islands since their discovery in 1786. The early travelers who made such complete 

 collections on Unalaska and other islands of the Aleutian chain seem to have spent 

 very little time on the Pribilof Islands, only 35 species being recorded from them in 

 Ledebour's Flora Bossica. I have been able to find no record of any collection hav- 

 ing been made there between the time of Chamisso and Eschscholtz and the purchase 

 of Alaska by the United States. Mr. Charles Bryant, in 1875, made a large collection 

 on the Pribilof Islands. A set of these plants is in the United States I^^ational Her- 

 barium at Washington, and, I believe, in the Gray Herbarium also. In 1890 Mr. 

 William Palmer collected about 100 species of flowering plants there, and many 

 mosses and lichens. The phaenogams were determined by Mr. Theodor Holm, the 

 mosses by Dr. Kindberg, the lichens by Mr. Calkins. In 1891 Dr. C. H. Merriam, one 

 of the United States Bering Sea commissioners, made extensive collections (over 90 

 species) on both St. Paul and St. George islands, and in 1892 published a list of the 

 plants he had collected.' In 1895 Messrs. F. W, True and D. W. Prentiss, jr., brought 

 from the Pribilof Islands a very fine collection of flowering plants (90 species). Their 

 specimens are the best I have seen froin that region. They were determined by Dr. 

 J. N. Rose and are in the National Herbarium at Washington. 



My own collections were made in the years 1891, 1892, 1896, and 1897, principally 

 on St. Paul Island, and comprise 182 species and varieties of phaenerogams and 

 vascular cryptogams. In 1897 1 had ample time at my disposal, and had then seen 

 the collections of other visitors to the islands, so that I was able to greatly extend 

 the number of species collected by me in former years. Eeference is made in the text 

 to tshe species that I failed to find. St. George Island has never been well botanized, 

 and future collectors on that island will probably add many species to this list. 



Through the courtesy of Mr. F. V. Coville and Dr. J. N. Rose, the curator and 

 assistant curator of the United States National Herbarium, I have been enabled to 

 examine all the Pribilof Island plants in that herbarium, and have admitted no species 

 into the present list of which I have not seen specimens.
