AMONG THE WILD FLOWERS. 139 
stems, and by the distinct fz¢# in the stems, 
which is not the case in any other plants of 
the great Division of ENnpocENns! to which 
they belong. Some of the species have long 
radical leaves like the stems. Some have leafy 
stems, and some are wholly without leaves. 
We have about 20 species out of the 200 that 
are known. The flowers are in a panicle 
which bursts forth either from the end or side 
of the smooth stem. The Perianth is 6-leafed, 
its divisions resembling the glumes of a Grass. 
It is impossible to describe the various species 
without a technicality that would be useless 
~ except in presence of actual specimens. 
1 All flowering plants are included in Two Great Divisions, 
—ExoceEns, which increase by addition of external layers; and 
ENDOGENS, which increase by the addition of new matter 
within.
