Mr. Hollick read a list of additions to the flora of Richmond Co., 
N.Y., with notes and specimens. The original catalogue, by Messrs. 
Britton and Hollick, in 1879 enumerated 1,050 species. Three ap- 
pendices issued since then contain respectively 46, 67 and 48 addi- 
tions, making a total of 1,211 species to date. Many of these can 
never be duplicated, owing to the localities having been destroyed_ 
The herbarium of the late Wm. H. Leggett contributed many of 
these, some of which were collected more than twenty years ago, 
The_ entire State flora at the present time embraces about i,_8oo 
species, distributed over an area of about 45,000 square miles. Rich- 
mond Co., with an area of only 59 square miles, contains two-thirds 
of this number. About fifty of these were new to the State when 
found. 
A communication from Mr. Frank Tweedy upon the flora of the 
Yellowstone Region, was read by Dr. Britton, who showed specimens 
of the plants mentioned. Mr. Schrenk made some remarks upon the 
structure of pine wood, and referred particularly to the supposed 
function of the internal lenticular spaces. 
One active member was elected.
