A pioneer tree endemic to Ecuador where it is known from six subpopulations in cloud forest of the western Andes. Collection locales range from near Apuela to the surroundings of Pilaló. Also collected in the Reserva Geobotánica Pululahua on the new and old Quito-Santo Domingo roads and in secondary forests of Nono. Should be present in the Los Ilinizas and Cotacachi-Cayapas ecological reserves. C. maxima seems fairly common and its principal threat is total deforestation. Subpopulations reported growing in very different habitats - Colombian record, two from the Peruvian Amazon and one from a cloud forest of Manabí - have not been confirmed by specialists. The type was destroyed in Berlin during the Second World War, but a syntype collected by L. Sodiro in Pululahua may be present in the QPLS herbarium in Quito.
