THE SUM OF HIS WORK 



was presented for the possibility of producing new 

 varieties through hybridizing old species, it should 

 be added that mention was made in a separate 

 section of numerous experiments with seedlings 

 of the ampelopsis, a new type of wax myrtle, and 

 "some charming, crossbred seedling tigridias, new 

 cannas, arums, amaryllis, brodiaeas, aquiligias, 

 asters, and a multitude of other things not yet 

 near enough to perfection to merit a special 

 description; yet some of the hybrids of which are 

 worthy of much study." A list of other species 

 that had been mutually hybridized begins with 

 the peach and almond, and names more than 

 twenty crosses between the various types of 

 orchard fruits — apricot, plum, quince, and apple, 

 as well as peach — in various combinations. 



Without detailing further examples, it may be 

 said that this body of evidence was overwhelming. 

 It could be supplemented indefinitely, of course, 

 by examples from other plants in my experiment 

 gardens. But without further elaboration, the 

 examples cited in my first two catalogs sufficiently 

 establish the fertility of hybrids of many species 

 of widely different families. 



Thenceforth there could never be any doubt 

 in the minds of practical plant developers that 

 true species, within certain limits of affinity, may 

 be interbred and produce fertile offspring.
