Type
Type: Tanzania, Ufipa District: Tatanda Mission, Bidgood, Mbago & Vollesen 2381 (K!, holo.)
Morphology General Habit
Perennial herb with several stems arising from a woody rootstock, 20–40 cm tall
Morphology Stem
Stems erect, sparsely branched above, pubescent
Morphology Leaves
Leaves mostly erect, some ascending, sessile or shortly petiolate; blade elliptic to oblong, 1.3–2.5 × 0.5–1 cm, serrate distally, entire at base, apex acute, base rounded, truncate or cordate and clasping stem, sparsely pubescent, glandular-punctate; petiole 0–1 mm long
Morphology Reproductive morphology Inflorescences
Inflorescence lax with 6-flowered verticils 10–50 mm apart; bracts ovate, 2 mm long, cuspidate, soon deciduous, the scar developing into a conspicuous bowl-shaped nectary; pedicels 2 mm long, spreading, slightly curved, flattened
Morphology Reproductive morphology Flowers Calyx
Calyx 6–7 mm long in flower, pubescent and with small sessile glands; posterior lip purplish, obovate, shortly mucronate; anterior lip with a distinct sinus between broad lateral lobes and narrow median lobes; fruiting calyx 8–11 mm long
Morphology Reproductive morphology Flowers Corolla
Corolla 12–14 mm long; tube 6–7 mm long, curved, dorsally gibbous, dilated towards throat; lobe of posterior lip entire; anterior lip concave around filaments
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens exserted 10–15 mm
Morphology Reproductive morphology Fruits
Nutlets pale brown, broadly obovoid, 2 mm long, smooth, producing a small amount of mucilage when wet.
Ecology
Brachystegia woodland on rocky hills; 1600–2050 m
Conservation
Although relatively restricted in range, the species is also found in disturbed woodland so it is unlikely that the range of the species is declining.
Note
Closely related to O. fimbriatum on account of the calyx morphology, but differing in having erect leaves that clasp the stem at their base. O. amicorum first flowers when there are very few leaves. The first leaves are very narrow, which may cause confusion with O. fimbriatum var. angustilanceolatum. However, unlike the leaves of the latter species, these young leaves still clasp the stem at their base and are sometimes toothed. O. amicorum also often has a shorter fruiting calyx, but there is no clear discontinuity in this character.
