The Vascular Flora of the North Central Texas Walnut Formation.
Political boundaries most frequently define local floras. This floristic project takes a geological approach inspired by Dalea reverchonii (Comanche Peak Prairie Clover), which is endemic to glades of the Walnut Formation. The Walnut Formation (Comanchean) lies on the drier westernmost edge of the Fort Worth Prairie. Its shallow limestone soils, formed from alternating layers of hard limestone and clayey marl, support a wide variety of habitats. Glades of barren limestone typically appear on ridgetops, grassland savannas form on eroding hillslopes, and seeps support a variety of hyper-seasonal vegetation. Preliminary results indicate floristic affinities to Limestone Cedar Glades of Tennessee and Kentucky and to calcareous Apacherian Savannas of Southwestern North America.
