LlLIACEAE Uvularia 



half inches wide. The first flowers expanded the last of July and insects 

 continued to visit the inflorescence until in September. Harry Dietz, a 

 visiting entomologist, observed within five minutes 2 species of Antho- 

 myids, 4 species of Muscids, 1 species of Ortalid, 2 species of Phorids, 

 and 1 species of Syrphid on one plant. It has been reported also from Cass, 

 Greene, Hamilton, Monroe, Putnam, Tippecanoe, and Vigo Counties.

966. UVULARIA L. 



[Anderson and Whitaker. Speciation in Uvularia. Jour. Arnold Arb. 15: 



28-42. 1934.] 



Leaves perfoliate; capsules obtusely 3-angled. 



Blades whitish-pubescent beneath; perianth segments smooth within or nearly so.. 



1. U. grandiflora. 



Blades glabrous beneath; perianth segments granular-pubescent within. (See ex- 

 cluded species no. 132, p. 1033.) U. perfoliata. 



Leaves sessile; capsules sharply 3-angled, acute at each end 2. U. sessilifolia. 



1. Uvularia grandiflora J. E. Smith. Big Merrybells. Map 633. Infre- 

 quent to frequent in moist, rich soil throughout the state. It is never found 

 outside of thick woodland, unless persisting after woodland has been 

 cleared, but does well in cultivation in sun or shade. This species has been 

 confused by some of our early authors with Uvularia perfoliata, the range 

 of which is shown by recent studies to be restricted to the Allegheny Moun- 

 tains and eastward to the Coast. 



Que., w. N. Y. to Minn., southw. to Ga., Tenn., and Kans. 



2. Uvularia sessilifolia L. (Oakesia sessilifolia (L.) Wats.) Little 

 Merrybells. Map 634. Colonies are infrequently found in the southern 

 counties where it grows in hard, clay soil, usually associated with beech, 

 beech and sweet gum, and lowland oaks. It propagates mostly from the 

 rootstocks and a note on one of my labels reads : "I found, in a low woods 

 about 3 miles southwest of Dale, Spencer County, two colonies about 10 X 

 20 feet and this species formed a mat over these areas."

1019. HEMEROCALLIS L. Daylii .y 



[Bailey. Hemerocallis: the day-lilies. Gentes Herbarum 2: 143-156. 

 1930.] 

 Flowers dark, tawny, fulvous or reddish orange, not fragrant, blooming in summer. 



1. H. fulva. 



Flowers light, clear yellow or lemon color, more or less fragrant, blooming in spring 



and summer. (See excluded species no. 133, p. 1033.) H. flava. 



1. Hemerocallis fOlva L. Tawny Daylily. Map 635. This species is 

 ornamental and on account of its easy cultivation it has been freely planted 

 since pioneer times. It never produces seed naturally in this country and 

 propagates entirely by its many tuberous roots. A. B. Stout, of the New 

 York Botanical Garden, has succeeded in producing seed by artificial polli- 

 nation. He has written many articles on the species and anyone interested 

 should read them.
