Description
Summary:Knowledge of county floras in Texas is crucial for determining species composition, management, preservation, and restoration across the state. Like most Texas counties, floristic data for Erath County, Texas, is poorly known. The objectives of this investigation were to compile a flora for Erath County, determine the introduced, endemic, threatened, and endangered species, as well as make comparisons to the county's original flora and that of the North Central Texas region. Field work was conducted from September 2003 to December 2009 at 35 sites in Erath County. In addition herbaria were searched to locate specimens from Erath County. A total of 870 species (888 taxa) were identified in 103 families. One hundred forty-four taxa were introduced while 744 taxa were native. Eighteen of the species are Texas endemics. There were two rare plants, Dalea reverchonii and Penstemon guadalupensis, but no threatened or endangered plants were found during the investigation. Four state-listed noxious species were collected during the investigation—Arundo donax (giant reed), Convolvulus arvensis (field bindweed), Tamarix chinensis, and T. gallica (salt-cedars). El conocimiento de las Floras de los condados de Texas es fundamental para determinar la composición, el manejo, la preservación y la restauración de las especies en todo el estado. Como la mayoría de los condados de Texas, los datos florísticos del condado de Erath, Texas, son poco conocidos. Los objetivos de esta investigación fueron compilar la Flora del condado de Erath, determinar las especies introducidas, endémicas, amenazadas y en peligro de extinción, así como hacer comparaciones con la flora original del condado y la de la región centro norte de Texas. El trabajo de campo se llevó a cabo desde septiembre de 2003 hasta diciembre de 2009 en 35 sitios en el condado de Erath. Además, se registraron herbarios para localizar especímenes del condado de Erath. Se identificaron un total de 870 especies (888 taxones) de 103 familias. 144 taxones eran introducidos, mientras que 744 taxones eran nativos. Dieciocho de las especies son endémicas de Texas. Había dos plantas raras, Dalea reverchonii y Penstemon guadalupensis, pero no se encontraron plantas amenazadas o en peligro. Durante la investigación se recolectaron cuatro especies nocivas incluidas en la lista estatal: Arundo donax (junco gigante), Convolvulus arvensis (enredadera de campo), Tamarix chinensis y T. gallica (cedros de la sal).
