Morphology General Habit
Shrub or perennial herb, 0.8–2(–2.5) m tall
Morphology Stem
Stem sericeous, rarely pilose or hirsute with white to purple hairs and with colourless sessile glands
Morphology Leaves
Leaves linear to narrowly ovate, (1.3–)1.8–5(–6) × 0.2–2(–2.9) cm, entire, apex shortly acuminate to obtuse, often with a point and often recurved, base attenuate to rounded, villous to sparsely pilose beneath; petiole 1–7(–8) mm long
Morphology Reproductive morphology Inflorescences
Inflorescence 6–19(–25) cm long, distinct, with verticils 10–30 mm apart, with 2-flowered verticels or up to 3-flowered cymes in axils of lower bracts; lower bracts resembling leaves; upper bracts violet in colour, subulate, 1–9 mm long, 0.5 mm broad, distinctly shorter than the leaves; bracteoles 1–2(–3) mm long; pedicel in flower 5–15(–20) mm long and in fruit 8–23(–27) mm long, normally longer than bracts with a joint above the middle
Morphology Reproductive morphology Flowers Calyx
Flowering calyx green to brown or purple, most intensely coloured at base, glossy, 4–9 mm long, 3–6.5 mm broad, velutinous to sericeous with white to violet hairs; fruiting calyx yellowish green to brown, often purple towards the base, strongly coriaceous, 11–17(–20) mm long, 7–15 mm broad, splitting into two parts
Morphology Reproductive morphology Flowers Corolla
Corolla 14–21 mm long, anterior lip dark reddish brown to blackish purple, the tube lighter in colour, protruding part villous to densely pilose, never with stalked glands; tube 8–11 mm long; posterior lip 2–4 mm long; middle lobe of anterior lip 6–10 mm long and 8–10 mm broad
