Morphology General Buds
Axillary buds densely white-pilose.
Morphology Leaves
Leaves (linear-)lanceolate, 3.5–12 × 0.5–2.8 cm, base obtuse to shortly attenuate, apex acute, apiculate, lower surface with subappressed often anvil-shaped hairs, particularly on principal veins and margin, hairs more scattered or absent above; lateral veins 3–5 pairs; petiole 0–7 mm.
Morphology Reproductive morphology Inflorescences
Inflorescence single-flowered, axillary but often crowded towards stem apex; bracts foliaceous, much-reduced upwards, with scattered glandular hairs; bracteoles linear or oblanceolate, 6–21 × 0.5–2.5 mm, hairs as leaves with interspersed spreading glandular hairs; flowers sessile.
Morphology Reproductive morphology Flowers Calyx
Anterior calyx lobe oblong-ovate to narrowly lanceolate, 8.5–18 × 2.5–5 mm, apex entire or notched for 0.5–2.5 mm, indumentum as bracteoles, dense, venation parallel; posterior lobe 9.5–18.5 × 2–4.5 mm, apex acute or attenuate; lateral lobes lanceolate, 7.5–11 mm long, widened hyaline margin towards base.
