Eucharis is a small genus in the Amaryllidaceae family from Central and South America.
Eucharis amazonica is widely cultivated, although very commonly confused with E. x grandiflora. Staminal cup measuring 11.2-13.8mm long to apex of teeth and 28-30mm wide, margins slightly recurved, interior stained green particularly along filamental traces, shallowly cleft between stamens. This species has a narrow distribution from Huallaga valley near Moyobamba and Tarapoto, northeastern Peru. This species is at least partly sterile (Meerow 1989). Viable seeds have never been produced in cultivation and is thought the whole population to be a single clone. Plants flowering at least twice a year, July-August and December-March. Flower fragrance is sweet and spicy and seems stronger during the day.
