bulbils, in the smaller size of the flowers and in somewhat dif- 

 ferent color and spotting. Evidently this plant was very similar 

 to that which the writer shows in fig. 4 accompanying this 

 article. 



One type of lily cultivated by the Chinese in Yunnan has been 

 considered as a hybrid between L. tigrinum and L. tenuijolium. 

 But Mr. Wilson in his recent book already mentioned assigns 

 this plant to the species L. Davidii. 



Possibly other hybrids, seedlings of L. tigrinum, have ap- 

 peared in the Orient and some may still be in existence there. 

 The readiness with which they may be obtained in experimental 

 breeding makes this quite probable. 



THE TIGER LILV AS A POLLEN PARENT 



The pollen of the tiger lilies is abundant and is highly viable 

 in artificial culture. A high percentage of the grains germinate 

 and there is a vigorous growth of the pollen tubes. The pollen 

 is excellent. There has been little opportunity to use this 

 pollen in the reciprocals of those crosses that yield fruit on 

 Lilium tigrinum. Only four flowers of L. Maximowiczii were 

 thus cross-pollinated and these were complete failures. But 

 when the pollen of the tiger lily was used in guarded and con- 

 trolled pollination on four flowers of Lilium warleyense, three fine 

 capsules and some viable seeds were obtained. This result is 

 sufficient to show that the pollen of the tiger lily is able to func- 

 tion in certain relations. 



Miss Preston reports that she obtained capsules and seed 

 from flowers of L. speciosum pollinated from the tiger lily but 

 that the seeds did not germinate. This cross has always failed 

 at the New York Botanical Ciarden. 



The writer has thus far found no other references to the ex- 

 perimental use of L. tigrinum as a pollen parent in breeding work. 



THE TIGER LILIES ARE ENTIRELY FRUITLESS TO ALL POLLINATION 



AMONG THEMSELVES 



During the past ten years more than 200 bulbs ot the tiger 

 lilies have been secured fn^m various sources for use in experi- 

 mental Studies at the New York Botanical Garden. These 

 include bulbs of the type most usually seen in cultivation, of the 

 varieties Fortuneiy splendens, and flore-pleno, and also of plants
