Scanning Electron Microscope (SEM) images of the apical part of the cypsela showing pappus setae/squamellae of Ophryosporus species. A–F Chilean species G, H Peruvian species previously referred to Chile (pappus absent in O. floribundus) A O. anomalus (FL 4102) with few spreading squamellae (arrowed) B O. heptanthus (FFM 2019-20) with conspicuous pappus setae C O. johnstonii (Johnston 5259) with long, erect pappus setae D O. paradoxus (Zöllner 6827) with long, erect pappus setae E O. pinifolius (FL 3452) with small, erect squamellae (arrowed) F O. triangularis (FFM 2018-63) with long, erect pappus setae G O. floribundus (Asplund 11079) with no visible pappus H O. hoppii (Dillon 3926) with squamellate pappus setae fused at the base and rather more conspicuous than in O. pinifolius.
