The present work exploits internet resources to update previously reported data for the distributional range and ecology of Cistanthe philhershkovitziana Hershk. (Cistanthe Spach sect. Cistanthe; Montiaceae), a conspicuous and not uncommon species of central and north-central Chile. The latitudinal range documented here is at least 4.8° greater than previously reported, extending from ca. 29°S (Huasco Province, Atacama Region) to ca. 33.8°S (San Antonio Province, Valparaiso Region). Possibly it extends further north to at least ca. 28.5°S. Morphological and ecological variability is discussed.
