Oxalis corniculata
species of plant

Oxalis corniculata, the creeping woodsorrel, procumbent yellow sorrel or sleeping beauty, is a somewhat delicate-appearing, low-growing herbaceous plant in the family Oxalidaceae.
Oxalis corniculata is a small creeping type of woodsorrel that tends to grow well in moist climates. It resembles the common yellow woodsorrel, Oxalis stricta.
Description
It has a narrow, creeping stem that easily takes root at the nodes. Its trifoliate leaves are subdivided into three rounded leaflets, resembling a clover. Some varieties have green leaves, while others, such as Oxalis corniculata var. atropurpurea, have purple leaves. There are inconspicuous stipules at the base of each petiole. The small, yellow flowers have either round-edged or sharp-ended petals. The flowers close when the plant is not within direct sunlight, hence the name "sleeping beauty".
Begin with the source’s own compact description: “Oxalis corniculata” is species of plant. The dossier treats that line as a proposition to test through Oxalis, corniculata and species, not as a finished interpretation.
Why this record matters
The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q162795. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
