The specific name honours Samuel Botsford Buckley (1809-1884), who collected the type specimen near Corpus Christi, Texas.
Tradescantia longipes, commonly known as the wild crocus, is a perennial herbaceous plant in the dayflower family. It is found only in the Ozark Mountains of southern Missouri and northern Arkansas in the Midwest United States. A spring blooming species, its flowers can be observed from April to May, typically in its preferred habitat of wooded slopes on rocky hillsides. While most other members of the genus in North America have stems reaching at least a few inches above the soil, the flowering shoots of Tradescantia longipes are borne essentially at ground level. This character is shared with some individuals of Tradescantia hirsuticaulis and Tradescantia virginiana, two closely related species, although both typically have obvious stems. Regardless, Tradescantia longipes can be distinguished from the former with its longer pedicels and bracts without fine hairs, and from the latter by the presence of at least some glandular hairs on the sepals. Furthermore, Tradescantia longipes is a tetraploid, meaning it has four sets of chromosomes, while Tradescantia hirsuticaulis is diploid with only two sets. Tradescantia virginiana occurs in both diploid and tetraploid forms, although it is consistently tetraploid where its range overlaps with Trandescantia longipes.
Tradescantia hirsuticaulis, commonly called hairystem spiderwort, is a species of plant in the family Commelinaceae that is native to south-central United States.
