Development of the Vegetation of New York State 45 
Following is a condensed outline of the plant kingdom 
giving, according to a rather old-fashioned classification, four 
sub-kingdoms with the larger natural groups under each. So 
far as data are given as to numbers of species they may indi- 
eate what the expectation may be for New York State. As 
a matter of fact I have not given much time to the collection 
of floral statistics. 
General Outline of Classification. 
I. Thallophytes. 
1. Bacteria. 
2. Blue-green algae. 
3. Green algae. 
Dr. M. A. Howe suggests a broad estimate 
for blue-green and green algae together, in- 
cluding desmids but excluding diatoms, of 
1200 species for New York. 
. Stoneworts. Chara, Nitella, ete. 
. Brown algae. Marine. 
. Red algae. Mostly marine. 
. True fungi embracing three greater and numer- 
ous lesser groups. 
a. Alga-like fungi (water moulds, downy 
mildews, black moulds, ete.). 
b. Sac fungi (blue moulds, powdery mil- 
dews, black fungi, cup fungi, morels, 
ete. ). 
e. Basidium-bearing fungi. 
(1) Rusts and smuts. 
(2) Coral fungi, polypores (bracket 
fungi, ete.), gill fungi (mush- 
rooms and toadstools as gen- 
generally known), puff balls, 
ete. 
The number of gill fungi alone estimated 
for Michigan is 1000 species. Dr. Peck? de-
