TERATOLOGICAL NOTES 



By C. Stuart Gager 



The following instances of structural abnormalities are not 

 presented as contributions. Most of them have been reported 

 before, and some of them often, either in the species here re- 

 corded, or in allied species. In complying with a request from 

 the editor of Torreya for an article on teratological observa- 

 tions, it was thought that those given below would be of popular 

 interest, and it is hoped that the paper may stimulate further ob- 

 servations, especially on the part of amateur botanists. 



Polycotyly and Syncotyly in Onagra biennis. — Seedlings of 

 dicotyledonous species having three cotyledons are of frequent 

 occurrence, and in " Die Mutationstheorie," de Vries describes 

 such seedlings for Oenotlicra Laniarckiana, 0. laevifolia, 0. lata, 

 and 0. rubrinervis. In experimental pedigreed cultures he found 

 the anomaly hereditary in less than three per cent, of the off- 

 spring of plants that possessed it. Fusion of the two cotyledons 

 into one was figured by de Vries for O. glauca, and, in crossing 

 half and middle races (" Die Mutationtheorie " 2 : 345), this was
