Type
Type: Ethiopia, Sidamo, ± 35 km from the main road Yabelo–Mega, on road to Arero, Friis, Bidgood, L. & W. Malaku & Gashaw 8374 (C, holo. ETH, K!, iso.)
Morphology General Habit
Aromatic annual herb 0.3 m tall, with a fibrous root system
Morphology Stem
Stems quadrangular, erect or ascending, sometimes reddish above, villose with long patent and retrorse eglandular hairs and shorter glandular hairs and with reddish sessile glands
Morphology Leaves
Leaves petiolate with clusters of younger leaves in axils; blades broadly triangular to trullate, 2–3 × 2–4 cm, deeply crenate with teeth themselves toothed, apex rounded or obtuse, base truncate and slightly attenuate at petiole, pubescent and with reddish sessile glands; petioles 10–25 mm long
Morphology Reproductive morphology Inflorescences
Inflorescence lax with 6–10-flowered verticils 5–10 mm apart, with bracts subtending 3–5-flowered sessile cymes; bracts inconspicuous, broadly ovate, 2–3 mm long, persistent, adaxially glabrous, margins and abaxial surface densely pubescent, with red sessile glands; pedicels 3–4 mm long
Morphology Reproductive morphology Flowers Calyx
Calyx 1–1.5 mm long, villose, with red and pale sessile glands; fruiting calyx 3 mm long, tubular, curved and with pedicel attached excentrically behind posterior lip; throat truncate; posterior lip elliptic or obovate, acute at apex, curving upwards, shortly or not decurrent; anterior lobes lanceolate with median lobes slightly longer and narrower than lateral
Morphology Reproductive morphology Flowers Corolla
Corolla white, mauve or blue, 4–5 mm long, pubescent with hairs and red sessile glands on lobes; tube 2 mm long, shallowly sigmoid; posterior lip shorter than anterior; anterior lip 2–3 mm long, horizontal, enclosing stamens or stamens just exserted
Morphology Reproductive morphology Flowers Androecium Stamens
Staminal filaments free
Morphology Reproductive morphology Fruits
Nutlets brown shiny with reddish dots, broadly elliptic in outline, flattened, 1 mm long, producing lots of mucilage speckled on outer surface.
Ecology
Rocky ravine in Acacia-Combretum woodland; 1000 m
Conservation
Also found in Sidamo and Harar regions of Ethiopia. Although not represented by many collections, the species’ similarity to P. hadiensis and small habit may lead to it being overlooked. This annual with a preference for more open habitats is probably not threatened.NOTE. Differing from P. hadiensis by the annual habit and persistent bracts. The corollas of P. minutiflorus are shorter, those of P. hadiensis only rarely being 5 mm long. Despite the disjunction, the K 6 specimen is a good match to other material.
