https://en.wikipedia.org/wiki/Lysimachia_foemina :
"Lysimachia foemina has weak, square and sprawling stems growing to about 5–18 centimetres (2.0–7.1 in) long,[7] which bear bright green sessile leaves in opposite pairs. The leaves are usually lance-shaped about 7–11 mm (0.28–0.43 in) wide and 12–16 mm (0.47–0.63 in) long, although some leaves, especially the lowest, may be ovate.

The small flowers are about 8 mm (0.31 in) in diameter, have a short stalk, are produced in the leaf axils and are usually blue. They have five lanceolate sepals and five petals. The filaments are about 3 mm (0.12 in) long, with showy yellow anthers. The flowering period extends from April to October.[7] The hermaphroditic flowers are pollinated by insects (entomogamy). The fruit is a spherical capsule up to 4 mm (0.16 in) in diameter containing about 15 seeds.[7]

This species is very similar to the related Lysimachia arvensis, and has been regarded as a subspecies of L arvensis. In 2007, a molecular phylogenetic study showed that Lysimachia foemina is more closely related to Lysimachia monelli than to Lysimachia arvensis, and should be treated as a separate species.[2]

Lysimachia foemina can be distinguished from Lysimachia arvensis on the basis of the hairiness and arrangement of the petals and by the length of the flower stalk. This species has just a few glandular hairs on the margins of the petals, clearly separated from one another (never imbricate). Furthermore the flower stalk is shorter (10 mm (0.39 in)). The colour of the flowers is not a useful diagnostic character.[7]"

plantago almogravensis
with @jmneiva; presumably the main area for this species, which looks very different from P. algarbiensis, namelly having much smaller leaves, and different habitus altogether;
common locally, a few smaller subgroups, whenever scrub wasn't dense
