IMPORTANT PRECAUTIONS 
Leaves growing from the root are not classed as either 
opposite or whorled, but are included under otherwise than 
opposite or whorled. 
" Flowers soHtary " does not necessarily mean that there is 
only one flower on the plant. It means that each flower is 
separately placed. 
A "flower-head," as that of the Dandelion, Daisy, or Clover, 
is classed as a single flower. 
When a single measurement is given, it indicates the average, 
not the exact size. 
When in doubt which of two groups, or which of two colors, 
to select, try both. 
Do not overlook those flowers which are referred to at the 
end of one group to be found in another. 
When in doubt what a word means, consult the glossary at 
the end of the book. 
Failing to find a flower by the chart, look through the pictures 
in order, beginning at the point where in doubt. For example, 
suppose the flower is yellow and the leaves are plainly oppo- 
site, but you are uncertain about the form of the flower-parts, 
look through all the yellow flowers in the class " Plants with 
opposite leaves;" if there is a doubt between yellow and white, 
look through that class in both colors. 
The term shrub is appHed, not only to a bush of consid- 
erable size, but to a low plant, such as Steeple Bush, if it has 
a woody stem.
