Notes

Perennial forb to 30cm tall or creeping.  Leaves alternating up the stems, each composed of three leaflets each 0.2-1.5cm long, 2-15mm wide, flat, sparsely to densely hairy, with a notched apex.  Flowers yellow, with 5 petals, in umbels of 1-6 flowers on stalks arising from the bases of the leaves.

Differs from Oxalis corniculata in that it has a stout taproot, and the outgrowths (stipules) at the bases of the leaf stems are usually inconspicuous.

Differs from Oxalis radicosa in that the hairs on the stems point upwards (visible with a hand lens).
