Notable examples of such plants are Andropogon scoparius
, ribwort plantain (Plantago lanceolata L., Holcus lanatus), mosses, lichens, crowberry (Empetrum nigrum L.), Tamarix (Tamarix parviflora), Eucalyptus (Eucalyptus camaldulensis), and Chinese Brake fern (Pteris vittata L.) [59-68].
Roos and Quinn (1977) reported that in early successional field population of Andropogon scoparius
had higher reproductive effort and a shorter developmental time than population of older site.
The mosaic system is a mixture of short-grass prairie on the more xeric, upland or south facing slopes and can be dominated by Bouteloua gracilis, Bouteloua hirsuta, Andropogon scoparius
, Carex filifolia, and Buchloe dactyloides (Kaul and Rolfsmeier 1993).
Those species that were seeded frequently, yet present infrequently ("ineffectively seeded") includes a mixture of eight native grasses and forbs: Andropogon scoparius
, Achillea millefolium, Agropyron riparium, Agropyron caninum, Ratibida columnifera, Bouteloua graeilis, Sporobulus eryptandrus, and Festuca ovina.
Although Index of Commonness values showed little bluestem (Andropogon scoparius
) to be the major species in all three survey areas before and after treatments, commonness results also showed that the study area was undergoing ecological succession during the six years of this study with Jerusalem artichoke (Helianthus tuberosus) and grass-leaved goldenrod (Solidago graminifolia) increasing in all survey areas.

and Bouteloua gracilis.
The vegetation is native tallgrass prairie, dominated by the perennial, warm-season matrix grasses big bluestem (Andropogon gerardii Vit.), little bluestem (Andropogon scoparius
Michx.), Indian grass (Sorghastrum nutans [L.] Nash), and switchgrass (Panicum virgatum L.) (Kuchler 1967, Freeman and Hulbert 1985).
On 6-7 July 1990 seeds mixed with damp sand were broadcast in each 9 x 9 m plot from one of 60 individually measured and weighed bags of six grasses (Agropyron trachycaulum (Link) Malte, Andropogon gerardi Vitman, Andropogon scoparius
Michx., Elymus virginicus L., Panicum virgatum L., Phalaris arundinacea L.), and 12 forbs (Allium cernuum Roth, Aquilegia canadensis L., Aster laevis L., Monarda fistulosa L., Oenothera biennis L., Penstemon digitalis Nutt., Ratibida pinnata (Vent.) Barnh., Rudbeckia hirta L., Solidago rigida L., Verbena hastata L., Zizia aurea).
Prior to European settlement, Maryland contained over 50,000 acres (20,235 ha) of serpentine habitats, consisting of two primary plant communities: little-bluestem (Andropogon scoparius
) dominated grasslands, and oak savanna characterized by stunted hardwoods, primarily blackjack oak (Quercus marilandica) and post oak (Q.

At the same time with this, or near the end of August, a to me very interesting genus of grasses, Andropogons, or Beard-Grasses, is in its prime: Andropogon furcatus, Forked Beard-Grass, or call it Purple-Fingered Grass; Andropogon scoparius
, Purple Wood-Grass; and Andropogon (now called Sorghum) nutans, Indian-Grass.
