Definition of loculus in English:



  • Each of a number of small separate cavities, especially in an ovary.

    • ‘In maize, the stomium is located at the meeting point of the two loculi that make up each half anther.’
    • ‘No vascular tissue was present in the septum, which forms a partition in the pod cavity between the two loculi.’
    • ‘Lacking an extensive vacuolization phase, meiocytes of the same tetrads stay together until the anther opens and the loculus reduces and disappears.’
    • ‘In the earliest stage available, septa in the cardinal quadrants form an uninterrupted septal stereozone; those of the counter quadrants are also heavily dilated, leaving very narrow interseptal loculi.’
    • ‘In early stages, septa in cardinal quadrants fully dilated; septa in cardinal quadrants less dilated, locally separated by moderately wide interseptal loculi.’


Mid 19th century: from Latin, compartment, diminutive of locus place.
