lakes and streams. It has been reported from Kosciusko, La Porte, Steuben, 

 and Tippecanoe Counties. The Tippecanoe County report is probably 

 based upon a cultivated plant. 1 found no specimen. 



N. B. to B. C. and southw. to N. Y., Ind., S. D., and Oreg. 



2. Viburnum acerifolium L. Mapleleaf Viburnum. Map 1934. In 

 dry woods in all parts of the state although there are neither records 

 nor specimens from 10 of the southwestern counties. It is usually a shrub 

 from 2-5 feet high but I measured a specimen in St. Joseph County that 

 was 7 feet high. 



N. B. to Minn., southw. to Ga. and Ala. 



2a. Viburnum acerifolium f. ovatum Rehder. (Jour. Arnold Arboretum 

 5: 241. 1924.) This is a form with leaves ovate, remotely dentate, and 

 subcordate. I found it in a white oak woods about 2 miles east of Gray- 

 ford in Jennings County. 



3. Viburnum cassinoides L. Withe-rod. Map 1935. So far as it is 



known this species is restricted to the northern tier of counties. Found 

 in low, sandy, black and white oak woods. Very local. There is a specimen 

 from La Porte County in the herbarium of the University of Notre Dame. 

 Buhl (Amer. Midland Nat. 16: 252. 1935) refers the report of Pepoon to 

 V. afflne or its variety. 



Newf. to Man. and Minn., southw. to N. J., Fla., and Ala. 



4. Viburnum Lentago L. Nannyberry. Map 1936. Rather frequent in 

 the lake area and occasional in boggy places south of it. It has been 

 reported from the southern part of the state but I believe all or at least 

 most of the reports should be referred to Viburnum prunifolium. This 

 species is difficult for some to distinguish from Viburnum prunifolium. 

 Most of the southern reports say that the specimens were found in dry 

 woods which is not the habitat of this species. I have seen it only in wet 

 woods and springy places.
