Key characteristics
This species differs from M. constitutionis by its 3-lobed (vs. undivided) leaves, lax (vs. densely corymbose) fruiting racemes, ascending to recurved pedicels 1.5−3.5(−4) mm long (vs. ascending to arcuate pedicels 3.5−6 mm long), and oblong and plump (vs. ovoid to slightly compressed) seeds. It also resembles M. linearis but differs by having 3-winged, usually non-callose (vs. valves 2-winged and strongly callose) fruit valves (Salariato et al., 2014)
