LlLIACEAE 



Lilium 



Perianth segments spreading (not recurving or scarcely so), base of perianth 

 a reddish purple; plants of dry, wooded slopes. .3. L. canadense f. rubrum. 



Perianth segments strongly recurved, orange or reddish orange on the outside; 



plants of a moist habitat such as prairies, marshes, and low woods 



4. L. michiganense. 



Leaves all scattered, none in whorls, the upper ones usually bearing black bulblets in 

 some of the axils; stem more or less gray-pubescent above; plants escaped from 

 cultivation 5. L. tigrinum. 



1. Lilium philadelphicum L. var. andinum (Nutt.) Ker. (Lilium umbel- 

 latum Pursh.) Western Lily. Map 642. It is doubtful whether the species 

 occurs in the state. All of the specimens I have seen belong to the variety 

 and I think all reports of it from Indiana should be referred to the variety. 



All of the reports of the variety and all of my specimens are from 

 northern Indiana. Our reports for the species, however, extend the range 

 to Hamilton, Vigo, Monroe, Clark, and Jefferson Counties and the Lower 

 Wabash Valley. Prince Maximilian, June 10, 1834, reported finding Lilium 

 Catesbaei in Knox County north of Hazelton. Since this species as now 

 known is not found in Indiana and its flowering season is much later, I 

 think this report should be referred to L. philadelphicum var. andinum. 

 This lily is local and all the specimens I have seen were found in wet 

 prairies or in similar habitats. Coulter, in his report from Jefferson County, 

 says : "Common on the sand flats." There is a specimen in the herbarium 

 of Wabash College collected in Harrison County by Clapp. 



Ont. to Sask., southw. to Ohio and Ark. 



2. Lilium superbum L. AMERICAN TURK'S-CAP Lily. Map 643. This 

 species has been reported from various parts of the state but I think it is 

 very rare and that most of our reports should be referred to Lilium michi- 

 ijunense. I have found it only three times and always on wooded slopes. 

 This species is easily confused with Lilium michiganense if the character 

 of the roughness or smoothness of the under surface of the leaves is 

 the only one used. The spreading of the perianth, which begins at the 

 base, and the length of the anthers will easily separate them, but the
