la the matter of basal rot there is a subtle factor worthy of mention. 
The purple form of L. Martagon which is native to Europe thrives in 
European gardens and is apparently not subject to basal rot. In this country 
the purple Martagon is a different story. There is no lily more susceptable 
to basal rot, even when it has been grown from seed here. The white 
Martagon, which is native to the same areas in Europe, thrives in both 
European and American gardens. These illustrations could be repeated 
many times with other well known varieties. All we can say is that in a 
certain environment a given lily tends to thrive — or the reverse. No one 
has as yet been able to put his finger on just what occurs. This will, of 
course, be an area for some future research. 
In addition to L. Martagon type, the following lilies are especially 
susceptable to basal rot in American gardens: L. chalcedonicum, L testa- 
ceum, L. croceum, L.pardalinum, L. Humboldtii, some of the Bellingham 
hybrids, L. pyrenaicum, L. formosanum, and L. speciosum. 
It may be of interest to note that basal rot is probably the principal 
factor responsible for the serious losses that frequently occur in seedling 
lilies. But on the whole the disease is of minor importance in the garden 
whereas it is very serious to the large commercial grower.
