Annual or biennial herbs, 0.5–0.9 m in height, covered with simple hairs. Basal leaves 85–180× 15–23 mm, lanceolate-obtuse, blade elliptic, softly hairy, deciduous. Stem leaves 40–65× 8–18 mm, lanceolate, apex acute, base cuneate, covered with moderately stiff hairs. Trichomes brittle, simple on both leaf surfaces. Inflorescence dichotomously branched axillary cyme, pedicel 1–1.5 mm long. Calyx ca. 1–1.5 mm long, lobe ovate-obtuse, pubescent on the outer surface, inner surface glabrous, apex acute. Corolla white with pale blue throat; lobes ca. 1× 1 mm, campanulate. Nutlets ovoid-convex, 3–4× 2.5–3.5 mm, fully pubescent; glochidia equally thick and long ( Figure 13).

Phenology. August to May.

Conservation status. Least Concern ( Raimondo et al. 2009).

Diagnostic characters. Amongst the southern African species, C. lanceolatum is similar and possibly related to Cynoglossum coeruleum subsp. johnstonii var. mannii with which it shares the branching pattern of the inflorescence, flower colour, and nutlet size. The two species can be distinguished by the density of the glochidia on the nutlets and distribution. Cynoglossum lanceolatum nutlets are completely covered with glochidia, whereas in Cynoglossum coeruleum subsp. johnstonii var. mannii glochidia tend to be more marginal and acentric.

Distribution and habitat. Cynoglossum lanceolatum originates from Yemen ( K ӧnig et al. 2015) but reported from Africa ( Ge-Ling et al. 1995), Pakistan, India ( Joshi 2016), the Mediterranean, and throughout Asia ( Verdcourt 1991) and Madagascar ( K ӧnig et al.2015). In South Africa it occurs widely in all provinces, it also occurs in eSwatini and Lesotho ( Figure 14). It is a widespread species that grows in disturbed habitats throughout parts of Africa.

Taxonomic notes. The specimen in the National Herbarium Pretoria ( PRE) collected in the Doornpoort area in Gauteng Province (Voucher number: S.P. Bester 9734 ( PRE)) belongs to C. lanceolatum and not to C. amabile since it has characters which are typical of this species, i.e., white corolla with a blue throat instead of bluish-purple corolla and divaricately branched instead of clustered at the apex.
