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.

Discodermia calyx species, among others with similar toxins, became increasingly studied and important in medicine, particularly relating to chemotherapy. In a later study, scientist concluded that the calyculin A, from "D. calyx," also blocks calcium influx by blocking non-selective ion channels in the cell. Later research looked into "D. calyx" as a species to look at the natural mechanisms that can be used to regulate the toxicity of calyculin A. Scientist found regulation through phosphorylation and dephosphorylation. These among other studies focus on regulation of the toxin as a characteristic of the sponge Discodermia Calyx because of its implications in the fight
