THE MAXIMUM HEIGHT OF PLANTS. II. 
John H. Schaffner. 
Last spring the writer published a few measurements of some 
common western plants in the Asa Gray Bulletin ( Vol. 8: 19-20). A few 
other measurements are given below, all from Kansas except four 
which are from Ohio. It would be well for all collectors to keep re- 
cords of the size of the plants which they meet, including measure- 
ments of the height and also dimensions of theleaves, flowers, fruits 
and underground parts. In this way the manual of the future may 
be brought to represent more accurately the living plant as it grows 
in nature rather than the dried, shrunken and dwarf specimens of 
the herbarium.
