1 December 2009 The Crassulaceae of Cajamarca, Peru

Eleven species of Crassulaceae were found in the Department of Cajamarca, northern Peru. (1) Echeveria eurychlamys was collected at its type locality for the first time since its description. (2) Geographical variants of Echeveria oreophila are described. (3) Echeveria cuencaensis, known previously only from Ecuador, is reported for the first time in Peru. (4) Sedum decipiens, a species common in Ancash, is reported from farther north. (5) Sedum isidorum is described as a new species related to S. decipiens, but forming redder, more compact plants. (6) Sedum reniforme is found at its type locality, which appears to be its northern limit; it is relatively more abundant farther south in Ancash. (7) Villadia klopfensteinii is described as a new species with greenish-yellow, bell-shaped, Echeveria-like flowers with stiff, fused petals. (8) Villadia aureistella is a new species with showy, star-shaped, yellow flowers, unique among Peruvian species in having a petal completely recurved to form a loop. (9) Villadia thiedei is a new species closely related to Villadia virgata from Chiquián, but the plants are taller and the flowers smaller, with incurving apices. (10) Villadia paniculata is a new species with panicles of spikes which, when bractless, resemble racemes; the apical flowers are greenish white with slightly recurving petals. (11) Villadia kimnachii is a new species with erect, narrow, lycopodium-like branches with adpressed, almost upright leaves and dense spikes of small flowers with distinctive salmon-colored nectaries.
