    Flora Zambesiaca Acanthaceae (part 2) by Iain Darbyshire, Kaj Vollesen and Ensermu Kelbessa

    Diagnostic
    sp. nov. Differs from B. mutabilis in the bracteoles being broadly elliptic to suborbicular, 7.5–17.5 mm wide (vs. linear, oblanceolate or narrowly elliptic, 0.5–4.5 mm wide), and in the posterior calyx lobe being markedly larger and broader than the anterior lobe and sometimes partially enveloping it (vs. outer calyx lobes subequal, the posterior lobe only marginally larger).
    Habit
    Shrub 100–200 cm tall; stems with dense golden long-armed stellate hairs, stellate base sometimes falling early, arm 0.5–1.3 mm long.
    Leaves
    Leaves broadly ovate, 2–8 × 2–4.8 cm, base subcordate or rounded, apex obtuse, acute or shortly attenuate, surfaces densely golden-hairy, hairs long-armed stellate or simple; lateral veins 5–6 pairs, these and reticulate tertiary venation prominent beneath; petiole 0–8 mm long.
    Inflorescences
    Inflorescences axillary but clustered towards stem apex, forming a terminal thyrse with reduced foliaceous bracts, each cyme contracted and strobilate, 3–8-flowered, unilateral or becoming branched at maturity, sessile or primary peduncle to 7.5 mm long; bracteoles broadly elliptic to suborbicular, 9.5–23 × 7.5–17.5 mm, apex obtuse to attenuate with a conspicuous mucro; flowers sessile.
    Calyx
    Calyx papery, green at first with a purple-brown apex, soon turning brown-purple scarious; anterior lobe suborbicular or broadly elliptic, 14–19 × 12–16 mm, base obtuse, rounded or cordate, margin irregularly dentate, somewhat undulate, apex obtuse or rounded, surface with golden long-armed stellate or mixed stellate and simple hairs, most numerous on veins; posterior lobe suborbicular 16–25 × 17–25 mm, margin often involute and partially enveloping anterior lobe; lateral lobes lanceolate-attenuate, 9–15.5 mm long.
    Corolla
    Corolla 37–44 mm long, lilac or blue, pilose eternally with mixed glandular and eglandular hairs; tube cylindrical, 21–22 mm long, curved below attachment point of stamens; limb in 2+3 arrangement; abaxial and lateral lobes 12–19 × 10–15 mm; adaxial lobes 7.5–10 × 5–8 mm.
    Stamens
    Stamens attached in distal half of corolla tube; filaments 16–20 mm long; anthers 4.5–5 mm long; lateral staminodes c.3.5 mm long, pubescent, antherodes obsolete or poorly developed, to 0.8 mm long.
    Ovary
    Ovary with apical tuft of hairs; style pubescent towards base; stigma clavate, 0.6–0.7 mm long.
    Fruits
    Capsule c.17.5 mm long, with few pale hairs towards apex.
    Seeds
    Only immature seeds seen.
    Distribution
    Not known elsewhere.
    Ecology
    Open forest, wooded slopes above river, and abandoned cultivated land; 1100–1200 m.
    Conservation
    Conservation notes: Endemic to Niassa Province in Mozambique and known from only the three cited specimens plus a photographic record taken by Meg Coates-Palgrave in May 2009 at Simanje R. near Lichinga, while Torre recorded it as widespread at Maniamba; best considered as Data Deficient.
