ON THE TIGRIDIA 



tall-growing plant bearing close resemblance to 

 the Tigridias, and by some botanists classified with 

 them. It has pale blue flowers marked with yel- 

 low, and the specimens are of a somewhat different 

 structure from those of the Tigridia, though the 

 bulb and general growth of the plant are similar. 



I particularly desired to introduce strains of 

 the Herbertia platensis, because this is a very 

 strong-growing plant, and its vigor and health 

 would be of great service in giving hardiness which 

 is the one thing that the Tigridias more especially 

 lack. 



In particular, the bulbs of the tiger plant are 

 difficult to keep over winter, and especially subject 

 to decay from exposure to air and to the attacks 

 of aphids when stored. 



But much to my disappointment I was never 

 able to effect hybridization between any of the 

 Tigridias, either pure bred or hybrid, and the Her- 

 bertia. The experiment was made over and over, 

 and in every case it was without result. 



Meantime, however, there was no difficulty 

 whatever in hybridizing the ordinary cultivated 

 strains of Tiger Flowers among themselves and 

 with some of their South African relatives. And 

 the results of such hybridizings were manifest 

 almost from the outset. 



One of the most striking modifications shown
