Schaffner — Height of Plants.

THE ?IAXIMUM HEIGHT OF PLANTS. H. 



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.
