Yellow-wort is a yellow-flowered member of the Gentian family. It grows from ten to fifty centimetres tall with stiff, branching stems. The leaves are glaucous, opposite and entire, the upper ones perfoliate, being united at the base. It bears terminal cymes of bright yellow, stalked flowers, 1–1.5 cm across. The calyx is deeply divided into 6–10 linear lobes or sepals, spirally arranged, free or nearly free from each other at the base and shorter than the corolla. The petals number six to ten and form a short tube. There are six to ten adherent stamens and a two-lobed stigma. It flowers from June to October in Britain where it is widespread but not common. https://en.wikipedia.org/wiki/Blackstonia_perfoliata Its main habitats are lowland calcareous grasslands and fixed sand dunes, but it can be an abundant colonist of disturbed ground, including quarries and railway cuttings, and on road verges and pathsides. There has been little change in the overall distribution of this species since the 1962 Atlas, although it has spread into Northumberland since then. https://www.brc.ac.uk/plantatlas/plant/blackstonia-perfoliata
