PERSONALITY OF PLANTS 
of Keeling, after thousands of years of existence, 
contained only twenty kinds of flowering 
plants. 
Although plants have no legs they are not de- 
void of mobility. When man uses the pro- 
pulsive power of steam to travel by, he shows 
no greater ingenuity than do plants in their 
use of special devices of locomotion. 
Species like the Tumble Weed (Amarantus 
Albus) pull up stakes, and, consigning them- 
selves to the swift autumn winds, race across 
country at great speed, scattering seeds as they 
go. The Utriculariae or Bladderworts are 
true sailors and float about on inland streams 
like little ships. The Duckweeds and Wolffias 
also have aquatic habits. 
However, most plants prefer to travel in 
embryo. In the form of small and microscopic 
seeds the force of gravity has little influence 
on them, and they can journey for long and 
incredible distances. 
To this end practically every seed in exist- 
ence is provided with some apparatus or ap- 
pendage designed to help it make its way in 
the world. The Elm, the Linden, and the Ash
