 var. interfus Fern. 



la. Smilacina racemosa var. cylindrata Fern. (Rhodora 40: 406. 1938.) 

 This is the southern form of the species. Although the variety and the 

 typical form of the species overlap with intermediate forms in Indiana, 

 the northern or typical form of the species and the southern form are 

 quite distinct. The two forms are found throughout the state. Both forms 

 are given on one map because the map was made before the variety was 

 recognized.

2. Smilacina stellata (L.) Desf. Starry False Solomon's-seal. Map 

 653. Infrequent to frequent in the northern half of the state and rare or 

 absent from the southern counties. It prefers moist soil and is most often 

 found on moist slopes and springy banks but is also found on dry banks, in 

 black and white oak woods, and is most abundant on the sand dunes about 

 Lake Michigan. The lower surface of the leaves is very variable, ranging 

 from glabrous to densely short-pubescent. Two varieties of this species 

 have been described and we have both of them, but I think, judging from 

 the descriptions, they are only ecological forms.

Lower surface of leaves glabrous; margins of blades merely papillate or crenulate

Lower surface of leaves pubescent at least on the veins; margins of blades ciliate- 

 pubescent la. M. canadense var. interius. 



1. Maianthemum canadense Desf. (Unifolium canadense (Desf.) 

 Greene). Two-leaf Solomon's-seal. Map 654. Infrequent but usually 

 common where found in low woods and in tamarack bogs throughout 

 the northern part of the lake area. I found it in Jefferson County in a 

 low, flat woods in soil of a pH value of 5.6 where it was associated with
