A CATALOGUE OF THE POISONOUS PLANTS OF 

 THE WORLD 



In the following catalogue an attempt has been made to record all of the 

 species that have been in some way or another regarded as poisonous or in- 

 jurious to man. This catalogue, however, is based mainly on the plants listed 

 by Greshoff, Cornevin, Chesnut, Ernst, Lyons, Maiden, Miquel, Radlkofer, 

 Rusby, Smith, White in "Dermatitis venenata," but includes also a few from 

 other scattered sources. The poisonous fungi were listed from Atkinson, Hard, 

 Clements, and some from Fries, Peck, Farlow, and Bulliard. It was not thought 

 best to list the fungi from the works of Ratzeburg and Phoebus entirely be- 

 cause of the uncertainty as to the poisonous qualities. It should be stated that 

 many of the plants in this list are not poisonous nor are they always given as 

 poisonous by the authors credited to them after the species, in fact, many of 

 them on the whole must be regarded as plants simply having medicinal virtues. 

 It was thought best, however, to list them, to permit future investigators to 

 take up the problem of the chemistry and poisonous qualities of these plants 

 from an experimental standpoint. It is simply an indication of the lines along 

 which work should be done. We have also indicated the action of the plant, or 

 in some few cases the important substance found in the plant. The alphabetical 

 arrangement has been adopted except as to the lower forms. In the last col- 

 umn the distribution is indicated usually only where the plant is indigenous, 

 but in some cases North America is added where the plant has been introduced. 



I have been greatly aided in this work by the excellent treatise of A. B. 

 Lyons, "Plant Names, Scientific and Popular," published by Nelson Baker & 

 Co., and also by the excellent work of Sayre, "Organic Materia Medica and 

 Pharmacognosy." 



In the preparation of this catalogue I have received very substantial help 

 from Miss Harriette S. Kellogg, who has looked after the details in catalogue- 

 ing the species and the synonyms. In some cases the synonyms could not be 

 found in the Kew Index, and these have been allowed to stand as they were 

 given by the authors. Some duplication of names may occur, and possibly 

 through an oversight some have been placed in the wrong orders, but I ask 

 the reader's indulgence in errors of this kind. 



Finally, I am indebted to Miss Bertha D. Herr for the laborious task of 

 getting the copy ready for the printer. L. H. PammEL.
