Mimosa texana is a shrub in the family Fabaceae.[2] 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.[1] 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.[3]
Distribution
[edit]Texas mimosa is found on alkaline soils in Mexico and Zapata and Starr counties in the state of Texas. It is uncommon and grows on caliche and gravelly hillsides.[4]
Description
[edit]This species is a straggly, much branched, deciduous shrub of up to two metres tall. It has slender, zigzag, dark coloured twigs clad in backward pointing prickles. The alternate bi-pinnate leaves have medium-sized leaflets. The globular flowers are creamy-white and cover the bush in the spring. They are intensely fragrant and attract numerous insects. The seed pods are brick red and flattened, with prickly edges.[4]
