Meadows and pastures are usually weedy. A few species that appear 

 to be somewhat more characteristic of these than of abandoned cultivated 

 fields are Triodia flava, Ran unculus bulbosus , and Plantago rugelii . . 

 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. 

 Leciiea racemulosa. 

 Tecoma radicans. 

 Soli dago juncea. 



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

 ( Andro-pogon 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 been 

 •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. 

 Lespedeza spp. 

 G-erardia. spp. 



Chrysopsis mariana. 

 Eericocarpus linifolius. 



10. Hedgerows and woods margins. — Many of the fields are bordered 

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

 shrubs and woody vines, which, likewise, in many places form a dense bar- 

 rier along the edges of the woods. Among the most conspicuous species are: 



Smilax spp. 

 Corylus americana. 

 Rhus spp . 



Vitis spp. 

 Clethra alnif olia. 

 Lyonia ligustrina.
