Figure i. A glimpse of a few of the hybrid day lilies in the experi- 

 mental plots at The New York Botanical Garden. The plants here shown 

 are quite typical of many of the hybrids between the variety luteola and 

 the species H. aurantiaca; they grow vigorously and give an abundance 

 of bloom, which stands in the upper reaches of the foliage or slightly 

 above. Most of the plants selected for propagation as new clonal varieties 

 have this habit of growth, combined with flowers of attractive shapes and 

 colors.
