Name: Buddleja racemosa - Ungnadia speciosa Shrubland Alliance
Reference: Southeastern Ecology Working Gro...
Description: This alliance consists of shrublands on outcrops of massive limestone in the Edwards Plateau of central Texas, characterized by Buddleja racemosa and Ungnadia speciosa. The only association described in this alliance occurs on limestone rimrock along mesic canyons in the southern portion of the Edwards Plateau of central Texas. It occurs on the Edwards Limestone, and geologically similar limestone formations. Normally, it occurs as a lengthy but relatively narrow band (5-10 m wide) along the flat upper surface of the rimrock. Dominant shrubs are Buddleja racemosa, Ungnadia speciosa, and Toxicodendron radicans ssp. eximium. A rare endemic shrub restricted to this community is Philadelphus ernestii. Herbs occur on exposed rock surfaces and in soil pockets, and include Aquilegia canadensis, Aristolochia serpentaria, Notholaena spp., and Pellaea spp. Upslope, this shrubland adjoins Juniperus ashei woodlands or Quercus fusiformis woodlands. Downslope (in the canyons), it adjoins mesic deciduous oak forests and woodlands. This alliance is geographically restricted and has a naturally limited acreage.
