Abstract

Crepis pusilla (Asteraceae, Cichorieae) is “Critically Endangered” in the Maltese Islands, being restricted to a 60 metre country path. This study is the first to quantify the population and to precisely determine its distribution. Field surveys between February and May 2023 indicated a total of 27 confirmed individuals or close clusters of Crepis pusilla with a diameter ranging between 0.9 cm to 4.8 cm (mean 2.5 cm ± 0.9 cm). Flowering was observed during April and early May 2023, with each plant producing c. 150 achenes.
