168 Rhodora [JUNE 
botanists, the late Francis L. Harvey, his son, Le Roy H. Harvey, 
Elmer D. Merrill, and P. L. Ricker, under the able escort of Capt. 
Rogers and his sons, entered the Great Basin by way of the modern 
Wassataquoik trail. It was too late for good botanizing, but a few 
novelties were found. These were recorded by Mr. Merrill in RHo- 
, DORA (i. 185, 186), his “Three Ponds” probably being the upper 
of the three, which for convenience and clearness is here designated 
as Depot Pond. 
The account of the most recent botanical explorations on the moun- 
tain is contained in the articles which accompany this. In order to 
bring to date such information as we now possess concerning the 
higher plants of Katahdin, all publications known to the writer have 
been examined and their records carefully noted. In the following 
list, if no authority for the report is given, the statement is based 
upon observations made in 19oo by the writer and his companions. 
A single asterisk (*) before the name indicates that this is the first 
record (at least in a published list) of the species or variety from 
Maine, while two asterisks (* *) indicate that the plant has not been 
previously recorded from New England.
