the edition of 1817, gave a much shorter list based mostly 
upon the work of Muhlenberg. In 1819, in “A Catalogue 
of Plants growing spontaneously within thirty miles of 
New York,” John Terrey also gave a list of 66 lichens. 
This is simply a record of species already known, but the 
list is the first considerable local one for a small North 
American area. A. Halsey, in 1828, in his “Synoptic View 
of the Lichens Growing in the Vicinity of the City of 
New York,” gave a list of 176 lichens with short diagnoses. 
This is the first work devoted wholly to North American 
lichens and published in this country, and it gives nine 
new species, named by Schweinitz. Halsey’s 176 lichens 
for the single locality appears noteworthy when we state 
that the whole number of lichens known in the State of 
New York at the present time is 241. Though Pennsyl- 
vania and New York are entitled to early pre-eminence in 
lichen studies, New England comes to the front toward 
the close of the period and more especially in the next 
period. So far as we are able to ascertain, besides Tucker- 
man’s beginnings to be considered later, a single catalogue 
of the present period gives any notice to New England 
lichens. This is “A Catalogue of Animals and Plants of 
Massachusetts” by Edward Hitchcock, in which he gives a 
list of 116 lichens. This catalogue appeared in 1888, and 
in the following year T. Nuttall, in his “Catalogue of a 
Collection of Plants made chiefly in the valleys of the 
Rocky Mountains or Northern Andes” by A. B. Wyeth, lists 
three lichens. This work is barely worthy of note as the 
first American paper giving a record of lichens from west- 
ern North America. Menzies had collected considerably 
on the Pacific coast before this time, but we find nothing 
previously published in this country regarding his work. 
Before passing to a brief notice of the portion of Tucker- 
man’s work belonging to the present period, we need only 
note further that Olney had listed three lichens in Rhode 
Island and that Russell, about 1840, noted 18 or 20 in 
Massachusetts, that from 1822 to 1888 Hooker, Presl, 
Bachelot, Wickstrom, Meyer and Ramon had all published 
more or less regarding our lichen flora, in Europe, and
