Distribution and Ecology - In thickets and waste places below 200 m, locally plentiful in Pacific lowland Ecuador (provs. Esmeraldas, Guayas and El Oro), and once recorded from Isla S. Cristóbal in the Galapagos archipelago.—Fl. III-IX. Map 53.


As mentioned in discussion of M. albida, the locally well characterized var. aequatoriana presents the foliage of that species combined with the pod of M. debilis. It illustrates and emphasizes the over-close relationship between these species, which are here maintained in the interest of convenience. Mutually exclusive definition of the pair is impossible unless var. aequatoriana is transferred to M. debilis, even though this taxonomic ruse may well not reflect its probable origin from vicariant M. albida.
