Morphology Reproductive morphology Inflorescences
Inflorescence axillary but in densely-flowered plants forming a terminal thyrse, 1–3-flowered; bracts foliaceous, often narrowing upwards; bracteoles linear(-oblanceolate) to narrowly elliptic, 6–22 × 0.5–3.5 mm, indumentum as leaves but with glandular hairs often more widespread; flowers (sub)sessile.
Morphology Reproductive morphology Flowers Calyx
Calyx somewhat accrescent; anterior lobe ovate, 5.5–14 × 2–6.5 mm, apex attenuate, entire or bifid with linear lobes 0.5–4.5 mm long, strigose on margin and principal veins, often also with scattered glandular hairs, venation palmate to subparallel; posterior lobe 6.5–16.5 × 2.5–7.5 mm, margin often involute and partially enveloping anterior lobe, apex attenuate; lateral lobes lanceolate, 3.5–6.5 mm long.
