Quantification of the size and distribution of the only known population of Crepis pusilla (Sommier) Merxm. (Asteraceae, Cichorieae) in Malta
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.
