Discussion | The record of this species from Indiana (E. Anderson and R. E. Woodson Jr. 1935) was based on a depauperate specimen of Tradescantia virginiana (E. Anderson 1954); the internodes on an unnumbered specimen collected by Mason, however, deposited at the Field Museum in Chicago, are puberulent with glandular and eglandular hairs. I have seen this character in an occasional specimen of T. bracteata but never in T. virginiana. Tradescantia bracteata was distinguished from T. occidentalis partly by the former's unbranched stems versus the freely branched in T. occidentalis (M. Bolick 1981). By using this feature, branching specimens from Minnesota would be identified as T. occidentalis, although their sepal pubescence and lax, green, pubescent-margined bracts and leaves clearly place them in T. bracteata.
