num bogs, and mucky places. The tuber on this species has always in- 

 terested me, and a few years ago I planted one year old seedlings with 

 a tuber and the second year I found that the tuber had decayed and, in 

 clay soil, the plant was, as usual, stoloniferous with many subterranean 

 tubers. Two year old plants were planted in clay, and they were more 

 proliferous and grew an incredible number of tubers. The limited number 

 of tubers in their native habitat is doubtless due to lack of nutrients. This 

 species is not satisfactorily separated from the next one and more study 

 is needed on all parts, especially on the flowers. 



According to Gray's Manual, the distribution is as follows : 

 Newf. and Lab. to B. C, southw. in the mts. to Va., Mich., Minn., Nebr., 

 Wyo., and Oreg. 



2. Lycopus virginicus L. Map 1782. This species is frequent in the 

 southern part of the state and infrequent to local in the northern part. It 

 grows in wet places in woodland, in ditches, and on the muddy borders 

 of sloughs and streams. 



N. H. to Nebr., southw. to Fla., Miss., and Mo. 



3. Lycopus sessilifolius Gray. Map 1783. This species is local. It has 

 been found in Jasper County in marshes about two and a half miles south- 

 east of Tefft, and in Starke County in a marsh near Bass Lake and in a 

 roadside ditch south of San Pierre. 



Costal Plain from Mass. to Fla. and Miss, and in n. Ind. 



4. Lycopus rubellus Moench. :!: Map 1784. Found sparingly throughout 

 the state. It is usually found in dried-up swamps and ponds in woods, often 

 on old logs, and in the moss on the bases of trees that are growing in or 

 on the border of ponds. 



Vt. to Minn., southw. to Fla., La., and Ark. 



5. Lycopus americanus Muhl. American Bugleweed. Map 1785. In- 

 frequent to frequent throughout the state. It is found in wet and moist 

 ground in all kinds of habitats. This species was reported by some of our 



* Variety arkansanus (Frcs.) Benner (Bartonia 15: 50. 1935.) occurs in Posey County.
