BotanicaUy, flowering plants are first classed under 
two great divisions. The classification is arranged 
according to the first leaves which come from the 
seeds. These seed-leaves are called cotyledons. The 
first class of plants has two seed-leaves, and are called 
dicotyledons, which means two seed-leaves ; the second 
have only one seed-leaf and are called monocotyle- 
dons. The irises, lilies and palms, as well as orchids, 
rushes, sedges, and grasses, belong to the latter class.
