Thelypodium wrightii
Study of extensive material that has accumulated during the past three decades reveals that the differences between subsp. oklahomensis and subsp. wrightii, which are based solely on variations in gynophore and fruit lengths, do not hold as clearly as previously thought (I. A. Al-Shehbaz 1973; R. C. Rollins 1993).
