A shrub endemic to Andean Ecuador. Known from the three collections. The type was discovered in 1900 on the Volcán Chimborazo, inside the Reserva de Producción Faunística Chimborazo. Two other subpopulations were collected around 1950: one from Cañar province (Tambo and Suscal) and another from Azuay. The species holotype was destroyed in the Berlin herbarium during the Second World War, but a photograph survives in two American museums. The isotope was recently found in the Q herbarium, identified with the number 95/17. In the QPLS herbarium, the L. Sodiro collection #34 is identified as M. obovata and may be an isotope or paratype. Apart from habitat destruction, no specific threats are known.
