Cacalia atnplicifolia L 



it has been reported from Hamilton, Lake, La Porte, and Tippecanoe 

 Counties. It is always found in moist or wet grounds, usually near a 

 stream, and it spreads rapidly by underground stems. I planted this and 

 the next two species in alluvial soil in bottomland, and the other two lived 

 only a few years, while Cacalia suaveolens has spread about a foot each 

 year through an adjacent bluegrass sod.

2. Cacalia atriplicifolia L. Map 2182. Infrequent to frequent through- 

 out the state. It prefers dry, open woodland, especially clayey oak slopes. 

 It has a varied habitat, however, ranging from the woodland to the moist 

 prairie habitat.

3. Cacalia Muhlenbergii (Sch. Bip.) Fern. (Rhodora 40: 356-357. 

 1938.) (Cacalia reniformis Muhl. and Mesadenia reniformis (Muhl.) 

 Raf.) Map 2183. Infrequent to local in the southern two thirds of the state. 

 It prefers the moist, rich soil of beech slopes but it is found also in other 

 types of moist soil, even in springy places. Ordinarily only a few plants 

 are found at a place, but in 1921 I was asked by a land owner, who lived 

 about five miles southeast of Greensburg, Decatur County, to identify an 

 obnoxious weed which he had in his woods on an open beech ridge and 

 which proved to be a vigorous growth of this species in almost a pure 

 stand over an acre or more.

4. Cacalia tuberosa Nutt. Map 2184. This is a local species found 

 only in marly springy places. Where it is found, it is usually a common 

 plant. Its absence in the northeastern part of the state is of interest. If 

 it occurs there, it is rare, because I have collected intensively in these 

 counties without finding it.
