Silene campanulata the lower ones lance-shaped to rounded, and the upper ones linear or oval. Nodding flowers occur in a terminal cyme at the top of the stem, as well as in some of the leaf axils. Each has a hairy, often glandular calyx of fused sepals. This bell-shaped green or purplish calyx is open at the top, revealing five white, greenish, or pale pink petals. The petals have multilobed or fringed tips. The stamens and three long styles protrude from the flower's center.

Calyx of Held Calyx of Held The Calyx of Held is a particularly large synapse in the mammalian auditory central nervous system, so named by Hans Held in his 1893 article "Die centrale Gehörleitung" because of its resemblance to the calyx of a flower. Globular bushy cells in the anteroventral cochlear nucleus (AVCN) send axons to the contralateral medial nucleus of the trapezoid body (MNTB), where they synapse via these calyces on MNTB principal cells. These principal cells then project to the ipsilateral lateral superior olive (LSO), where they inhibit postsynaptic neurons and provide a basis for interaural level detection (ILD), required for
