Oxalis rubricallosa flowers

The flowers of Oxalis rubricallosa are borne in a few umbels upon a base umbel here; a secondary umbel structure with few flowers each. The umbels grow on long peduncles; each flower on a short, hairy pedicel. The five narrow green sepals with acute tips are quite long, with brick-brown tips clutching its corolla.

The corolla has a deep funnel-shape from the gradual opening of the five petals. The petals are pale yellow, darkly lined from the base. The slightly spiralling arrangement of the petals is seen both in the lines up the throat, as well as in the bias of the squarish-tipped petal lobes, creamy white in colour. The yellow anthers are visible in the picture below the taller stigma.
