papers given dealing with his special collections, as far as they are known to the author.
        In the above-mentioned manuscript of an Alaskan flora by P. C. STANDLEY, which is now kept in U. S. National Museum, Division of Plants, and which was very kindly placed at my disposal, a list of collectors is given up to the year 1915.  I have made free use of the information available there, especially in regard to the full names and profession of the collectors and about the size of their collections.
        Whenever it has been possible, I have tried to reconstruct the routes taken by collectors, with the corresponding dates. This is necessary as collectors often use local names not found on any map.  In many cases it is possible to locate such places with the knowledge of the collector’s itinerary and the corresponding date.
        In order to facilitate the study of the routes a map of Alaska and Yukon has been appended.  Most of the places at which botanical collections have been made are given on this map.  At the same time the map is intended to give some idea of the botanical survey of the country in its present state.  Places where comprehensive botanical collections were made, and where only single additional species of vascular plants may be expected to occur besides those known today, have been marked in capital letters; places where good collections have already been made, but where considerable additions may still be expected, are marked in medium-sized letters, and, lastly, the names of places where less comprehensive collections have been made are given in small letters.  Places where no botanical collection has yet been made have not been inserted in the map.  This map should therefore give a fairly complete picture of the botanical research-work done within the area.
