Endostemon tenuiflorus
species of plant
Endostemon tenuiflorus is a species of flowering plant in the family Lamiaceae and commonly called the slenderleaf keepsafe or, sometimes in South Africa, the mopaneveld keepsafe.
Description
This species is a perennial, softly sticky dwarf shrublet 0.15–0.25 m (5.9 in – 9.8 in) tall, woody at the base and freely branched. The stems are ascending and covered with fine glandular bristles.
The leaves are subsessile and often leathery, with linear to linear-oblanceolate blades, 12–40 mm (0.47–1.57 in) long. The surfaces are roughened by numerous sunken glands, with blunt tips, narrowed bases, and margins that are obscurely and distantly toothed, often rolled under.
The inflorescences are lax racemes 50–70 mm (2.0–2.8 in) long, composed of several spaced whorls, each bearing two flowers. The bracts are 1.5–5 mm (0.059–0.197 in) long. The calyx is spiny and strongly veined, hairy within the throat, and enlarges to about 3.5 mm (0.14 in) at maturity; the tube is bell-shaped, with narrow, awl-shaped lateral teeth shorter than the lower pair. The corolla is whitish to mauve or pink, 8–9 mm (0.31–0.35 in) long, with a cylindrical tube and short lobes.

Why this record matters
“Endostemon tenuiflorus” is worth following because a concise public description often conceals a longer documentary argument. Here, Endostemon, tenuiflorus and species provides the most credible route into that argument.
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 6, 2026. The linked authority identifier is Q15319898. 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.
