The four blue-purple Heliophila juncea petals of each flower spread widely above the small, green calyces ending in tiny, pointed, but erect sepal lobes. The petal lobes, much bigger than the sepals, have narrow, whitish claws at their bases, and rounding at their tips.
These soft, about oblanceolate floral limbs are neither neatly nor similarly positioned in the flowers of the photo, an imprecision best blamed on artistic flair, or the wind. The thin fleshy pedicels, however, all ascend in roughly similar fashion from the stem. This makes them innocent of causing the loss of perfection in adhering to the floral model.
As if such perfection might be a requirement of effective pollination (Vlok and Schutte-Vlok, 2015; Manning, 2007; iNaturalist; https://www.fernkloof.org.za).
