These results clearly demonstrate that the flowers of the tiger 

 lilv are fully able to function in producing fruit. The plants have 

 not lost their ability to yield fruit and viable seeds. They merely 

 require a proper cross-pollination with certain other types. When 

 this is done, anyone may obtain seeds and grow the hybrid 

 seedlings. 



Capsules with viable seeds may also be secured in other 

 crosses. To pollen of Lilium Leichtlinii, twenty-six flowers of 

 the tiger lily gave ten good capsules containing many viable 

 seeds and sixteen partly developed capsules. Of thirteen flowers 

 given pollen of L. davuricum Wallacei two were complete failures, 

 nine yielded partially developed capsules, and two matured 

 capsules with a few viable seeds. The species L. Leichtlinii is 

 obviously rather closely related to the tiger lily. Although the 

 variety Wallacei is listed as a variety of L. davuricum or L. 

 elegans it has a flower of rather striking resemblance to that of 

 the tiger lily. The tiger lilies do not set fruit so readily in these 

 crosses as they do with L. Maximowiczii and L. sutchuenense. 

 One experiences a greater number of failures. The require- 

 ments for fertilization are more exacting and less compatible. 



The seeds obtained in all these crosses have been planted and 

 the seedlings which survive will be grown to maturity. Thus 

 far only one has bloomed. It has the L. sutchuenense as a pollen 

 parent. This plant does not have bulbils in the axils ot the 

 leaves. Its flowers somewhat resemble those of the tiger but 

 diflFer slightly in color and in spotting (see fig. 4). 



To pollen of several other species, the tiger lilies have given 

 mostly complete failures and only occasionally a poorly matured 

 capsule. Thus far only such results have been obtained when 

 pollen of L. warlcycnscy L. pseudotigrinum^ ami /-. Batemanniae 

 was used. Of all the lilies thus far studied by the writer those of 

 L. Leichtlinii and L. pscudotigrinum most closely resemble 

 L. tigrinuin, yet of these two only the former has successfully 

 crossed with it. 



The true identity of the plants obtaineil under these species 

 names is a matter on which the writer does not wish to attempt 

 a final opinion. Mr. Wilson in "The Lilies of Eastern Asia" 

 does not recognize some of them as good species, 'i'iie plants 

 which the writer obtaineil under these ilifl^erent names were 

 clearly of somewhat ditt'erent ami ilistincr types. It not good 

 species they were at least xarieties.
