English: A single ripe (fallen) fruiting calyx of Scopolia carniolica Jacq. dissected to show detail of dehiscence: calyx slit to base, with a single cut, and sides pulled back to reveal two-chambered pyxidium with operculum (lid) still somewhat attached but having liberated a single pitted brown seed and revealing more ripe seeds inside the capsule, ready to be shed. Image brightened: screenshot of original image brightened by the use of various editing filters, the better to show colour and pitted testa texture of seeds and structure of dehiscent pyxidial seed capsule. Note artifact of concentric grey rectangles at image margin, created as side effect of application of filters to screenshot.
