American Medicinal Leaves And Herbs and has been prepared to meet the steady demand for information of this character. It is intended as a guide and reference book for those who may be interested in the study or collection of the medicinal plants of this country.

Less difficulty will be encountered in the collection of leaves and herbs than in the case of other portions of plants, for not only is recognition easier, since, especially in the matter of herbs, these parts are usually gathered at a time when the plants are in flower, but the labor is less arduous, for there are no roots to dig or barks to peel.
Of the three dozen medicinal plants mentioned in this bulletin, 15 are recognized as official in the Eighth Decennial Revision of the United States Pharmacopoeia. This is more than half of all the leaves and herbs included in the Pharmacopoeia.

Thirty-six plants furnishing leaves and herbs for medicinal use are fully described, and in some instances brief descriptions of related species.
