The Echeverias of the Chillón River Valley, one of the three rivers that run through Lima, the Capital city of Perú, are reviewed. Three new taxa are recognized and described: two new species and a new variety. (1) Echeveria deltoidea is a large species with narrowly triangular, light green to glaucous-purplish leaves, and large salmon-colored widely pyramidal flowers. It differs from E. chiclensis in its larger and broader, flatter leaves. It has been mistaken for E. andicola but this latter has smaller, prismatic, evenly orange-red flowers and smaller obovate-oblong leaves instead. Its rosettes are as large as in E. excelsa but this species has obovate leaves with obtuse apices. (2) Echeveria fruticosa is a new species with conspicuous aerial stems, erect or decumbent, each crowned by a rosette of rhomboid-obovate leaves, glaucous to bright green, narrowly rhomboid to obovate and wider than the linear oblong leaves of E. chiclensis. It has urceolate, light yellowish-green flowers with a blush, redder when exposed. (3) Echeveria chiclensis var. cantaensis is a new variety of Echeveria chiclensis with lighter greener leaves and shorter flowers than the type variety, yellowish with a blush, redder than the other two varieties. It could be mistaken with E. andicola but this species has slightly smaller flowers and wider leaves. It thrives at the Huaura, Chancay and Chillón River Valleys at lower altitudes than var. chiclensis from the Rímac River and Lurín River Valleys. In the Northern range, it reaches very low altitudes. (4) Echeveria chiclensis var. backebergii is also found in the area, although it does not differ too much from the populations of the type locality in the Rímac Valley.
