of both is manifested in all its characters, producing a 

 fusion of the different peculiarities. This is more evident in 

 the species than in the variety hybrids; in the latter some of 

 non-essential characters of the parent sometimes present 

 themselves in the offspring uncombined side by side; e. g-, 

 various kinds of streaks and blotches instead of a mixino' of 

 the colors of the flowers. Thus a hybrid which Sagaret 

 obtained from Ctjbcumis Ghate (female) with C- Melo 

 Cantalupus (which had a reticulated flesh) had a yellow 

 flesh, a reticulated marking of the rind and moderately 

 prominent ribs like the male parent, but white seeds and an 

 acid flavor like the female parent. Another hybrid from 

 the same species had, on the contrary, the sweet flavor and 

 yellow flesh of the male, with the white seeds and smooth 

 rind of the female parent. 



As a rule, hybrids may be produced reciprocally, but 

 sometimes this does not occur. Thus Koelreuter found that 

 when the pollen of MiraMlis longiflora was applied to 

 M. Jalapa, a hybrid was produced, but the reverse ex- 

 periment failed. 



An extraordinary number of rose hybrids have

been produced. It is said that on the average 



sixty new rose hybrids come on the market every year. 



The statement has been made that more than 6,400 roses 



have been produced up to the present time by crossing and 



hybridization. 



Quite a large number of hybrids have been produced at 

 the Iowa Agricultural College between Rosa rugom-, Rosa 

 Arhansana and cultivated roses. 



Rosa rugosa and General Jacqueminot- They pre- 

 sent some remarkable variations. In color of flower, leaf 

 and seed the hybrids indicate weaker germinating capacity.
