Headows and pastures are usually weedy. A few species that ap] 

 to be somewhat more characteristic of these than of abandoned cultivated 

 fields are Triodia flaya, Ranunculus bulbosus , and Plantago rugel i i . 

 Plants that do not occur elsewhere generally but that are conspicuously 

 abundant on the sandy terrace soils of the west and east tracts are: 



Eragrostis spectabilis. 

 Smilax glauca. 

 Potentilla canadensis. 

 Desmodium spp. 



Lespedeza spp. 

 Lechea racemulosa. 

 I'ecoma radicans.

Within 2 or 3 years after a field has "been abandoned, broomsedge 

 ( Androoogon virginicus ) begins to appear. It soon becomes dominant and 

 maintains dominance until it is crowded out by invasion of pines. Pinus 

 virginiana and P. rigida both invade broomsedge fields, but the former is 

 nearly everywhere in much greater abundance. Sassafras officinale is also 

 found in old fields, commonly appearing in the poorer soils soon after the 

 fields have been abandoned. On sterile slopes- and hilltops, bluestem ( Andro- 

 pogon scoparius ) is sometimes dominant. These areas appear to have beer. 

 cleared for a much longer time and they are changing much more slowly than 

 are the more typical older fields. Common species associated with stands 

 of bluestem are: 



Desmodium spp. 

 Lesr>edeza spp. 

 Gerardia spp. 



Chr; T sopsis mariana. 

 Sericocarpus linifolius. 



10. Hedgerows and woods margins. — I'any of the fields are bor 

 by hedgerows dominated by a variety of trees having dense undergrowth of 

 shrubs and woody vines, which, likewise, in man*.' places form a dense bar- 

 rier along the edges of the woods. Among the most conspicuous specie |
