Solenopsis laurentia

Solenopsis laurentia is an annual herb reaching 8–13 cm in height, with a solitary, erect, and glabrous stem. Leaves are cauline, 10–20 mm long, oblanceolate to spathulate, with entire to weakly crenate margins and petioles 3–5 mm long. Flowers are solitary on axillary pedicels 2–6 cm long, with 1–2 bracteoles and a calyx 3–4 mm long with linear-lanceolate lobes. The corolla is tubular, 5–6 mm long, bilabiate, with bluish-lilac lobes and a whitish lower tube. The lower lip bears clavate papillae. Stamens are fused to the corolla, with violet anthers. The ovary is fused with the calyx tube. The species is distributed across southern Europe and North Africa, from Portugal to Turkey and Morocco. Linnaeus originally described it as Lobelia laurentia, but it was later transferred to the genus Solenopsis by C. Presl in 1836. Nomenclatural revisions include the designation of a lectotype and epitype to stabilize its application.
