Description:
This limestone glade community is found in the Upper West Gulf Coastal Plain of Oklahoma (Goodland limestone) and adjacent southwestern Arkansas (DeQueen and Dierks limestone). Occurrences of the community are typically on narrow exposures, 23-61 m (75-200 feet) wide. These sites are predominantly droughty and very dry by the end of the summer, but they can be seasonally wet, with water occasionally ponded in shallow depressions during winter and early spring. The overall aspect is herbaceous, with woody plants largely confined to islands where pockets of deeper soil are found. The woody plants of these areas include <i>Maclura pomifera</i> (which may be dominant), <i>Juniperus virginiana, Ulmus crassifolia</i>, and <i>Symphoricarpos orbiculatus</i>. The most typical grasses of these glades are <i>Bouteloua curtipendula, Eragrostis spectabilis</i>, and <i>Schizachyrium scoparium</i>. The other most frequent plants of the glade openings include <i>Allium canadense, Anemone berlandieri, Astranthium integrifolium, Croton capitatus, Echinacea pallida</i>?, <i>Heliotropium tenellum, Leavenworthia aurea, Lesquerella angustifolia</i> (which can be abundant), <i>Monarda stipitatoglandulosa, Ranunculus fascicularis, Rudbeckia hirta, Clinopodium arkansanum, Packera tampicana</i>, and <i>Thelesperma filifolium</i>. Other occasional forbs include <i>Callirhoe papaver, Chaetopappa asteroides, Chamaesyce nutans, Dracopis amplexicaulis, Stenaria nigricans, Hypoxis hirsuta, Neptunia lutea</i>, and <i>Ruellia humilis</i>. Outcrops and limestone fragments are present at the surface, which are of minor areal extent but diagnostic of the community type. Soil is often thin or nonexistent, but where deeper soil exists, it is dark (black) and cracks when dry, illustrating a relationship to the blackland prairie.
