Mimosa texana is a shrub in the Fabaceae family. It is commonly known as the Texas mimosa, the Texas catclaw or the Wherry mimosa and is endemic to upland regions of Mexico and Texas. This species used to be classified as Mimosa biuncifera but it was found that phenotypic variations occurred across its range and a new taxonomy was proposed by Rupert C. Barneby in 1986, splitting the species into Mimosa aculeaticarpa var. biuncifera and Mimosa texana.
