Lilies is being carried on by Dr. A. B. Stout, with the assistance 

 of Miss Rusk, selfed seeds have also been obtained from many 

 Other varieties such as Lilium henryi, humboldtii, philadelphicum 

 and many others. The Lilies are grown under glass. My list 

 is short as I have only been working three years. All my work 

 is done out of doors and with the help of cold frames. 



Certain varieties of Lilies will often produce seed when fertilized 

 with pollen from a different variety, though incompatible to pollen 

 of their own kind. This is true of Lilium tigrinum. This Lily was 

 found to give seed when crossed with L. maximowiczi at the 

 Botanical Gardens. The cross has not bloomed yet. 



The right pollen to give seed on L. hansoni and L. testaceum has 

 not been found; pollen from species blooming earlier or later will 

 have to be saved and experimented with. 



Other ways of propagating Lilies, beside seeds are from bulbils 

 and bulblets and bulb scales. 



The tigrinum forms tiny black bulbils in the axils of the leaves. 

 When these are planted they grow quickly and flower two years 

 from the time of planting. 



Just above the ground along the stem of the speciosum and 

 many other Lilies, tiny bulblets are found. Bulblets are also 

 often attached to the mother bulb. These also flower two years 

 from the time they are planted. 



Sometimes, instead of one or two shoots coming from a bulb 

 it looks as if someone had dropped a packet of seed in that par- 

 ticular spot. When this happens it is wise to carefully dig up 

 this bulb. It will be seen that a sprout has come from each scale. 

 These scales with their sprouting stem and leaf can be pulled 

 apart and planted separately and will in turn form new strong 

 bulbs. Scales can be planted before this happens, too. 



All my seeds are planted in flats six inches deep, filled with a 

 mixture of two parts soil from the woods and one part sand. The 

 flats are put in a cold frame and during the summer are shaded 

 with slats and watered twice a day. In winter they are covered 

 two feet deep with leaves and the glass is put over them. I found 

 no difference in growth in seeds planted in the fall right after 

 ripening and the seeds planted the following spring. Canadense
