This inflorescence of Onoseris hyssopifolia was photographed near Cayambe, a glacier-covered volcano located on the western edge of the Cordillera Real at the Earth’s equator. Cayambe last erupted in 1786, but a number of low magnitude-earthquakes were reported in late 2016-early 2017. The volcano is located within the 40,000 hectare Cayambe-Coca National Park, an area of exceptional biodiversity including over one hundred species of endemic flowering plants. Onoseris hyssopifolia is not quite endemic (there are references, including Encyclopedia of Life, reporting it in Bolivia), but it is seemingly restricted to higher elevations in the Andes. To get a sense of habitat, you can review the photographs on this tourist guide to Ecuador’s Pucará de Rumicucho.
The specific epithet of Onoseris hyssopifolia means “leaves of Hyssop“: for comparison, the leaves of Hyssopus officinalis and the leaves from the original published illustration of Onoseris hyssopifolia (and the original 1818 description, in Latin).
