    Calyx
    Calyx white, 2.5–4.2(–4.7) cm long of which the basal tube 2–5 mm, glandular-pubescent with glands to 1 mm long; lobes linear to narrowly elliptic, acute
    Corolla
    Corolla pure white or with tube greenish towards base, cylindric tube 3.5–5 cm long and ± 2 mm in diameter, throat funnel-shaped, 0.7–1.2 cm long and 7–8 mm in diameter at apex, pubescent with curly hairs to 1 mm long; lobes spreading or reflexed, elliptic or narrowly so, 1.8–2.8 × 0.5–0.8 cm, subacute to rounded

    Figures
    Fig 41, p269
    Ecology
    Evergreen lowland and lower montane forest (including secondary forest), usually on edges, in clearings and along streams, riverine forest; 10–1500 m, but around Nairobi – where originally introduced – to 1650 m
    Note
    T. Anderson (l.c.) cites “ Ruellia longifolia P.Beauv. in Fl. Owar. 1: 45 as basionym for his Whitfieldia longifolia. But there is no such name in Flora Owariensis. He cites Ruellia elongata as a synonym, but with R. longifolia P.Beauv. being a fictitious name this is the correct name.
