A few researches have been concerned with the structure and pollination of alfalfa flowers. Others have considered the biological problems concerned in the pollination and fecundation of the flowers. In none of these studies, however, has an attempt been made to follow carefully the alfalfa flowers through various stages of development. Nor has any effort been made to determine what effect the condition and duration of these stages may have upon the resulting seed crop

The work that follows is a study of the changes through which the alfalfa flowers pass during the season while functioning as organs of seed production. Special effort has been made to study the condition and duration of the stages as they are related to the subsequent seed crop.
