Excerpt from A Synopsis of the Genus Arachis<br/><br/>In the hope of drawing up a usable and complete key, the genus has been restudied. The three publications cited have been evaluated, and a study has been made of the Arachis specimens in the herbarium of the United States National Arboretum  which, as a result of expedi tions sponsored by the Section of Plant Introduction, are probably the most comprehensive existing representation of the genus  and those in the United States National Herbarium. The results of the restudy are presented here. For purposes of comparison and discus sion, English translations are presented of the keys of Chevalier and Hoehne as rearranged in dichotomous form, and of the key of Burkart. The one wholly logical key of those heretofore published appears to be that of Burkart, its only shortcoming from the present standpoint being its restriction to the five species occurring in Argentina.
