Lampranthus stenopetalus fruit capsule

The dry fruit capsule of Lampranthus stenopetalus appears hard, is usually woody. The capsule is funnel-shaped at its base.

The five closed valves seen on the locules cover the seeds that are inside or may have been inside. Erect ridges are visible at the valve margins, usually referred to as valve wings. These wings and also the closing bodies that swell when wet and shrink when dry contribute to the hygrochastic capacity of the capsules. This allows the valves to open when wet and close when dry, regulating intermittent seed dispersal when moist conditions favour germination (Smith, et al, 1998; iNaturalist; Wikipedia; https://asknature.org).
