Type: Tanzania, Mpanda District: Silkcub Highlands, Richards 7127 (K!, holo.)
Morphology General Habit
Aromatic perennial herb with several stems arising from a woody rootstock, 0.6–1 m tall
Morphology Stem
Stems erect, quadrangular, branching above, pubescent, sometimes densely so, with appressed hairs
Morphology Leaves
Leaves ternate, very rarely opposite, usually ascending, more rarely with some spreading; blade elliptic 3.5–6 × 1–2.4 cm, frequently folded along midrib, deflexed, entire, weakly revolute or thickened at margin, apex acute or obtuse, base cuneate, glabrous or sparsely pubescent with hairs confined to veins beneath; petiole 4–6 mm long
Morphology Reproductive morphology Inflorescences
Inflorescence condensed, with 6–9-flowered verticils touching in flower and 10–15 mm apart in fruit; bracts subulate, 2 mm long, erect above and forming an inconspicuous apical coma, soon deciduous, the scar developing into a bowl-shaped nectary; pedicels 2 mm long
Morphology Reproductive morphology Flowers Calyx
Calyx 5–7 mm long in flower, sparsely pubescent and with sessile glands; posterior lip obovate, ciliate; lateral lobes of anterior lip truncate, densely ciliate, median lobes subulate-aristate; fruiting calyx ± 10 mm long
Morphology Reproductive morphology Flowers Corolla
Corolla white or pale lilac, 9–13 mm long; tube 5–8 mm long, slightly curved, dorsally gibbous, abruptly dilated at throat; lobes of posterior lip toothed or sinuate
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens exserted 10–20 mm
Morphology Reproductive morphology Fruits
Nutlets pale brown, broadly obovoid, 2 mm long, smooth, producing a small amount of mucilage when wet.

Restricted in distribution but habitat probably not in decline.
Note
O. pyramidatum is related to O. decumbens, O. vandenbrandii (Ayob.) A.J. Paton (from the Marungu Mts, on the other side of Lake Tanganyika in the Katanga) and O. urundense on account of the folded and deflexed leaf apex. This species is probably closest to O. urundense or O. vandenbrandii, which also have weakly revolute leaves.
