PLANT HYBRIDIZATION BEFORE MENDEL 29 



In all, Haartman gives a list of 100 hybrid plants, of which 

 descriptions are given in the case of 59. The cases most note- 

 worthy from the historical standpoint have been cited. 



On June 11, 1746, appeared, as Dissertation 9, in the "Funda- 

 menta Botanica," the "Sponsalia Plantarum" (8a) of Johan. 

 Gustav Wahlbom, one of Linnaeus' pupils, which undoubtedly 

 also represents the ideas of Linnaeus himself. Since this essay con- 

 sists entirely of a general discussion upon the sex of plants, it will 

 not be necessary to take it into consideration here.
