Only a pair of buds usually develops in a Pelargonium tetragonum mini-umbel. Purposefully pointed and angled on their long pedicels, these ready buds are making a statement of floral promise as the sepals slowly relinquish their grip on the corollas.
The third party in picture is a newly closed calyx, red-ridged on its old sepals with stamen and style detritus protruding from the yet again firmly closed mouth. This is the after-flower getting ready for exposing its fruit to crown the production sequence (Vlok and Schutte-Vlok, 2015; iNaturalist).
