PREFACE 
Mohr’s Plant Life of Alabama has been used as a basis for 
this Bulletin. The arrangement of Engler and Prantl, as 
adopted in that work has been closely followed here, and the 
nomenclature used by Mohr has been used in this list, except 1m 
a very few instances. No species has been included in the list 
unless it is found in our herbarium or is mentioned in the notes 
of the writer or of Mr. T. L. Bailey, or is credited to the State 
by some reputable author. A few species have been included on 
the authority of a partial list of plants found with the Hilgard 
Manuscripts, and presumably made by Dr. Hilgard, though no 
name was attached to the list. 
While work on collecting the state’s native plants was in 
progress the Geological Survey received the gift of a valuable 
collection of about 450 species from Mr. Andrew Allison, an ex- 
eallent field botanist, who collected mainly in two ecunties— 
Tishomingo and Hancock. Unfortunately for botanical science, 
Mr. Allison left the state several years ago to take up missicn- 
ary work in China. On his return, on vacation, in 1918, Mr. 
Allison very kindly presented to the Geological Survey Her- 
barium his beautiful collection, which is frequently referred to 
in the list as “‘ Allison Herbarium’’ (abbreviated, ‘‘ All. Herb.”’) 
Our list of grasses is taken almost entirely from the splen- 
did Tracy Collection in the Department of Botany of the Missis- 
sippi Agricultural and Mechanical College, free access to which 
was given through the courtesy of Professor J. M. Beal. 
During the summer months of 1914, 1915, and 1916, Mr. 
Thomas L. Bailey, an advanced student of the University of 
South Carolina, and an accomplished and enthusiastic field bota- - 
nist, was employed by the Survey, and scoured the state from 
end to end, taking valuable notes, and making large collections, 
all of which are deposited with the Geological Survey. These 
collections, together with notes and colections made by the writer 
for the past several years, furnish the material for this Bulletin. 
We do not claim that a complete list is-herewith furnished of 
the flowering plants and ferns of the state. Doubtless many 
species will be added as the list is known to be incomplete, and
