Ecology & Natural History
Habitat: Species is distributed in dry soil (Ref. 8), alluvial bottomland of the Missouri and Mississippi Rivers, prairies, and moist open places (Ref. 4). As for Muhlenbergia glomerata, there is a conflict between attributed habitats listed in the several references. Ref. 7 explicitly says M. racemosa lives in dry places, along railroads, and roadsides, and is often confused with M. glomerata of wet places. Item 78 (natural communities) follows Ref. 7. ILPIN Notes: Species has thick, contracted panicle, like M. glomerata, but this species has glabrous internodes, scaly rhizomes. Michaux type is from southern Illinois. Ref. 7, of Swink et al. says this and M. glomerata have been confused in different references. This has resulted in diametrically opposed habitats being listed under each species. Species is more common in western half and northern tip of state; uncommon in eastern half of state. Functional Relationships:
