in a strictly prairie habitat, which fact might be used to support their 

 separation, but I am not able to find any constant structural difference.

14. Salix Bebbiana Sarg. (Salix rostrata Richardson.) Bebb Willow. 

 Map 749. Rather frequent in the lake area and rare south of it.

 Pursh in part.) BOG Willow. Map 750. Infrequent in the lake area with 

 an outlying post in the Elliott's Mill Bog in Wayne County. It is a small

16. Salix Candida Fliigge. Sage Willow. Map 751. This is an infre-

 generally found with sedges, cranberry, and bog-rosemary.

16a. Salix Candida var. denudata Anders. This variety differs from the 

 species in having narrower leaves, which are glabrate or glabrescent on 

 both sides, especially above, and sometimes glaucescent beneath. I have 

 only one specimen from a bog on the south side of Pigeon River about 2 

 miles east of Mongo, Lagrange County. 



17. Salix adenophylla Hook. (Salix syrticola Fern. Rhodore 9: 225- 

 226. 1907.) (Schneider. Jour. Arnold Arb. 1: 158-160. 1920.) Glandleaf 

 Willow. Map 752. Formerly more or less frequent along Lake Michigan at 

 the base of the first dune on the side facing the beach. It is now nearly 

 extinct on account of the encroachments of civilization and the attacks of 

 the oyster-shell scale. 



Lab. to James Bay, southw. to the Great Lakes, including Ohio, Ind.,
