HEMEROCALLIS AURANTIACA AND HEMERO- 

 CALLIS AURANTIACA MAJOR 



the name Hemerocallis aurantiaca was bestowed by Baker 

 in 1890 (Gardeners* Chronicle, vol. 68, p. 94) on a plant 

 then growing in the Royal Botanic Gardens at Kew, 

 England. But Baker's description of this plant does not 

 correspond fully to any Day Lily now known — a point 

 recently made by L. H. Bailey (Gentes Herbarium, vol. 2, 

 p. 153, 1930). Hence the questions arise as to (1) what 

 plant Baker did describe and (2) whether that plant is 

 representative of a species which grows in the Orient. 



It is known that Baker's plant was propagated and dis- 

 tributed and that it soon found its way into gardens and 

 nurseries. It received rather favourable consideration in 

 horticultural circles and it was used in hybridizations that 

 gave new clons of value in garden culture. But at the 

 present time somewhat distinct types of Day Lilies are 

 being cultivated in Europe and America under the name 

 H. aurantiaca. Some of these have flowers of orange colour- 

 ing only; some have flowers with fulvous colouring in 

 addition to the orange; and there are other differences to 

 be noted. One of these types is without doubt the clon 

 that was obtained by the repeated propagation of Baker's 

 plant, but there seems to be no definite record which 

 allows one to trace a continuous clonal pedigree back to 

 that plant. 



The writer has obtained and studied Day Lilies bearing 

 the name H. aurantiaca from various sources in America, 

 Europe and Japan. Some of these are of other types ob- 

 viously incorrectly named. Even the double-flowered ful- 

 vous Kwanso Day Lily has been received under the name 

 H. aurantiaca. One type, first obtained by the New York 

 Botanical Garden in 19 13, appears to be more widely dis-
