Morphology Leaves
Leaves ovate or elliptic, 3.3–13.5 × 1.4–6 cm, base attenuate or cuneate to obtuse or rounded, apex acute, subattenuate or obtuse, surfaces with long-armed stellate hairs as on stems, stellate base sometimes falling early particularly above, margin of young leaves sometimes with spreading glandular hairs; lateral veins 4–5 pairs, prominent beneath; petiole 2–12 mm long.
Morphology Reproductive morphology Inflorescences
Inflorescences axillary towards stem apex, sometimes together forming a loose thyrse, each cyme contracted, (2)3–12-flowered, unilateral or often branching at maturity; bracteole pairs spreading and often deflexed, linear, narrowly elliptic or oblanceolate, 5–20 × 0.8–4.5 mm, margin entire or minutely toothed, apex mucronate; pedicels 0–2.5 mm long.
Morphology Reproductive morphology Flowers Calyx
Calyx papery, at first bluish or purple-tinged with darker reticulate venation, soon pale-scarious; anterior lobe obovate, elliptic or (in our region) ovate-orbicular, 8–21.5 × 4.5–19.5 mm, base cuneate to truncate or rounded, margin subentire or denticulate, apex rounded to attenuate or emarginate, indumentum as leaves, glandular hairs mainly on margins and apex or absent; posterior lobe slightly larger, apex obtuse to attenuate, mucronulate; lateral lobes (ovate)lanceolate, 6.5–12.5 mm long.

Morphology Reproductive morphology Flowers Androecium Stamens
Stamens attached 10–16 mm from base of corolla tube; filaments 12–16 mm long; anthers 3–5.2 mm long; lateral staminodes 1.2–3.5 mm long, pilose and with minute stalked glands, antherodes barely developed or to 0.8 mm long.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary with an apical tuft of short hairs, sometimes with a few pale hairs towards apex; style pubescent towards base; stigma clavate, 0.7–1.5 mm long.
Morphology Reproductive morphology Fruits
Capsule 13–16.5 mm long, sparsely pilose towards apex or with an apical tuft of hairs only.
