Distribution and Ecology:— Southestern United States, Mexico, Central America West Indies, and South America ( Venezuela, Colombia, Peru, Argentina, Paraguay, Bolivia, and Brazil) in accordance to ( Schubert 1980, Vanni 2001, Aymard et al. 2007, Lima et al. 2010). In Brazil D.glabrum occurs in the States of Alagoas, Bahia, Ceará, Goiás, Mato Grosso do Sul, Minas Gerais, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, and Tocantins. Collected in grassland, pasture, along roadsides, in Caatinga or Cerrado vegetation associated with Seasonally Dry Tropical Forests and Chaco.

Conservation Assessment:— Least Concern (LC), not endangered ( IUCN 2001).

Phenology:— flowering and fruiting from February to October.

Etymology:— from the Latin glabrous in reference to the terminal fruit article glabrous at maturity.

Common Name:— açoita-cavalo; brinquinho; carrapicho; engorda-cavalo; engorda-magro; marmelada-decachorro; marmelada-de-cavalo; rapadura-de-cavalo; vassourinha.
