 flowers. 



There are several somewhat different clones in garden culture 

 which resemble the Lemon Daylily and seem to be related to it. 

 One of these, which came to The New York Botanical Garden as 

 Hemerocallis minor, has smaller flowers, very erect foliage, and 

 beaked capsules. This clone is self-incompatible but readily crosses 

 with the Lemon Daylily. Various of the plants received as H. 

 flava from botanical gardens in Europe are somewhat different 

 from the type clone. The name "H. flava major" is applied both 

 to the type and to other daylilies. Some of the garden clones called 

 H. flava and H. flava major are certainly hybrids ; others may have 

 arisen as seedlings of the original clone of H . flava. 



In respect to the chromosome number, the Lemon Daylily has 22 

 (2 x 11), which is the normal diploid number for the genus. It is 

 not unusual or noteworthy in its chromosomal complex, as is the 

 triploid H. fulva clone Europa. 



Eastern or central Asia is without doubt the native home of the 

 daylilies and the center of their natural evolution, origin, and dis- 

 tribution. Certain of them are of ancient cultivation in the Orient 

 for food, for medicinal uses, and as garden flowers. The Lemon
