Abstract
A new species, Miersia putaendensis (Amaryllidaceae), endemic to Central Chile, is described. The new species differs from all known species of Miersia by featuring a white staminal tube with a purple spot and two upper linear, cuneiform floral appendages directed towards the front in its frontal lobe, the apex of which is toothed and deflexed. It inhabits southern slopes of sclerophyll woodlands and scrubs, particularly along rocks. Currently, the species is critically endangered. A detailed description, illustration, distribution map of the new species, and a dichotomous key with all accepted species of Miersia are provided.
