Stems somewhat villous. Leaves with petioles 2–6 mm long; lamina oblong to elliptic, 10–40 mm long × 2–15 mm wide; base cuneate, truncate or rarely attenuate; apices acute or rarely obtuse; sparsely villous on lower leaf surface, glabrous or glabrescent above. Flowers solitary or in pairs. Peduncles 5–35 mm long at anthesis, sparsely villous. Pedicels 5–8(–15) mm long, sparsely villous. Bracteoles lanceolate, 6–12 mm long × 0.5 mm wide, villous. Calyx lobes lanceolate, elliptic or obovate, unequal, 6.5–9.5 mm long × 2–4 mm wide; apices acute, attenuate or rarely rounded with a short attenuate point; villous, often only along the margins and midrib. Corolla 15– 30 mm long, intense blue-lavender to almost white, with a yellow centre. Stamens with filaments 5–7(–9) mm long on the shorter three, 6.5–8(–11) mm long on the longer two, the shorter filaments with stalked glandular hairs for the lower 1/3, the longer pair entirely glabrous; anthers 2–3 mm long on the longer filaments, 1.5–2.5 mm long on the shorter filaments. Ovary narrowly conical, 1–2 mm long, white, glabrous. Style white, 4–6 mm long. Stigma lobes 4–5.5 mm long, equal or nearly equal in length to the style (fig. 2d).
Distribution:— In Spain (Almeria, Alicante [Cabo Nao] and Mallorca [Marina de Llucmajor and Illa de s’Espartar; Sáez and Rosselló 2001]), northeastern Morocco (Gareb and Beni Snassen Mountain areas as defined by Valdes et al. (2002)) and northwestern Algeria (Oran Province; fig. 2a).
Habitat:— Growing in dry pastures and disturbed areas, often alongside roads.
Phenology:— Flowering and fruiting April–June.
Conservation:— At a global level, this species meets the criteria for Least Concern (IUCN 2001). However, in Spain, it exists in a number of small, highly disjunct populations and molecular data suggest that plants from Alicante may be distinct from the rest (fig. 1). In the Balearics, C. valentinus is recognised as critically endangered (Category C2a(ii); Sáez and Roselló 2001)
