|discussion=<p>Both R. L. Stuckey (1972) and R. C. Rollins (1993) indicated that <i>Rorippa sessiliflora</i> has strongly saccate sepals, but all specimens that I examined failed to show any sign of this character. The species is very distinctive and can easily be distinguished by an absence of petals and by having fruiting pedicels 0.5–2(–4) mm.</p>
