Abronia macrocarpa
''Abronia macrocarpa'' is a rare species of flowering plant known by the common name largefruit sand verbena. It is endemic to eastern Texas, where it is known from three counties.〔(Texas Parks and Wildlife )〕〔(The Nature Conservancy )〕 It inhabits harsh, open sand dunes on savannas, growing in deep, poor soils.〔(Center for Plant Conservation )〕 It was first collected in 1968 and described as a new species in 1972.〔〔Galloway, L. A. (1972). ''Abronia macrocarpa'' (Nyctaginaceae): a new species from Texas. ''Brittonia'' 24:2 148.〕 It is a federally listed endangered species of the United States.
==Description==
Abronia macrocarpa is a perennial herb with a hairy, glandular stem growing up to half a meter tall. The glandular oval leaf blades are up to 5 centimeters long by 3.5 wide and are borne on relatively long petioles. The inflorescence is a cluster of up to 75 magenta or light purple flowers each up to 3 centimeters long. The tubular, strongly fragrant flowers open at dusk and are pollinated by moths.〔 The winged fruit is up to 1.5 centimeters long. It is dispersed by wind.〔
Threats to this endangered species include habitat loss as its range is consumed for development and oil exploration.〔〔 The habitat is also damaged by off-road vehicles, people on foot and on horseback, fire suppression activity, and the invasion of non-native species such as bermudagrass and weeping lovegrass (''Eragrostis curvula'').〔〔
The total remaining number is estimated at several thousand individual plants in nine populations.〔
