340 GENERAL PLANT PATHOLOGY 



Worsdell's^ "Principles of Plant Teratology" includes a consideration 

 of the fungi and bryophytes as non-vascular plants and with vascular 

 plants he goes as far as a consideration of the teratology of roots, stems, 

 leaves and flowers. It is issued by the Ray Society, as was that of 

 Maxwell T. Masters in 1869.
