--><p>Myosurus sessilis often grows with M. minimus, and hybrids between the two species are common. Because the plants mostly set seed by self-pollination, these hybrids often give rise to inbred lines showing the characteristics of the two parents in various combinations (D. E. Stone 1959). The names M. alopecuroides Greene and M. sessilis subsp. alopecuroides (Greene) D. E. Stone are based on the hybrid M. minimus × sessilis or on inbred lines descended from this hybrid.</p>
