2. Muhlenbergia Schreberi J. F. Gmel. Nimblewill. Map 218. Infre- 

 quent to frequent throughout the state. It is found usually in dry soils 

 and less frequently in moist soils in open woodland, clearings, woods pas- 

 tures, and pasture fields. It is usually conspicuous in pasture fields because 

 stock graze around it, preferring other herbage. It is also found about 

 dwellings and in lawns and is an obnoxious weed in flower gardens.

3. Muhlenbergia sobolifera (Muhl.) Trin. Map 219. This species is 

 found principally in the southern half of the state. It is strictly a wood- 

 land species and occurs on wooded slopes, preferring those along streams. 

 It is found in both beech and sugar maple, and black and white oak 

 woodland.

4. Muhlenbergia cuspidata (Nutt.) Rydb. PLAINS Muhly. Map 220. 

 This species is infrequent on the high, gravelly bank of the north side of 

 Big Wea Creek where the Shadeland Road crosses the creek about 4 miles 

 southwest of Lafayette. Its associates make it certain that it is a native 

 here.

5. Muhlenbergia glabriflora Scribn. (Rhodora 9: 22. 1907.) Map 221. 

 This species, as now known, is restricted to seven of our southwestern 

 counties. It is found in hard, white clay soil in moist or wet places, usually 

 in pin oak woods or in the pin oak and post oak flats of the southwestern 

 part of Posey County. Probably locally frequent and possibly well distrib- 

 uted in the southwestern counties where its habitat is found.
