Oxalis ciliaris var. ciliaris corolla tube and calyx

A cluster of long-petioled, trifoliolate leaves grow from the top of the bare, erect stem of Oxalis ciliaris var. ciliaris.

The long-pedicelled flowers grow solitary, also from the top of this stem. Each flower has a long, narrowly funnel-shaped corolla tube, ending in five spreading, pale pink lobes.

There are also five less conspicuous, narrow and acutely pointed sepals in picture, at this stage adhering to the base of the corolla tube. The sepals are hairy and nearly half as long as the corolla tube.

Apart from a younger plant nearby and not yet flowering, there is a dry, erect stem in picture, possibly grown from the same geophytic base during an earlier season (Curtis-Scott, et al, 2020; Vlok and Schutte-Vlok, 2015; Bond and Goldblatt, 1984; iNaturalist).
