    Habit
    Small tree or shrub 3–5 m tall; stems angular at nodes, densely pubescent to glabrescent, hairs simple, stellate and subsessile-glandular
    Leaves
    Leaves suborbicular, 20–23 cm long, 23–26 cm wide, shallowly 3–5-lobed, apex acute, margin dentatecrenate, base deeply cordate, upper and lower surface densely pubescent; petiole 18–27 cm long; stipules caducous, lanceolate, 1.2–1.6 cm long, 0.5–0.6 cm wide, acuminate, tomentose. Inflorescence axillary, 4–5 cm long, subumbellate, 4–7flowered; peduncle 0.4–1 cm long, tomentose; bracts not seen; branches absent; pedicels 0.6–1.2 cm long; epicalyx bracts at calyx base, narrowly lanceolate, 2–2.4 cm long, 0.3 cm wide, long-acuminate, sparsely puberulous, persistent
    Calyx
    Calyx lobes erect, narrowly triangular, 3–3.5 cm long, 0.4–0.5 cm wide, acute, stellate-pilose
    Corolla
    Petals 3.1–4.7 cm long, (1.9–)2.6–3.2 cm wide.
    Androecium
    Androecium 2.6–3 cm long; staminal tube cylindrical (0.9–)1.5–1.6 cm long, staminodes ± 1.6 cm long, longest stamen ± 1.9 cm long; anthers 0.4–0.6 cm long
    Ovary
    Ovary subglobose, tomentose, style 2.1–2.9 cm long, 5–6-branched, pubescent
    Fruits
    Fruit and seeds unknown.
    Ecology
    Marshy places in forest, by rivers, and in wooded grassland; 300–1000 m
    Conservation
    Flora districts: Known from a few collections at five localities (area of occupancy estimated to be less than 500 km2); its habitat is threatened with a decline in quality at one of these localities by ongoing wood extraction (Luke and Vollesen, pers. comm. 2005). The taxon is accordingly here assessed as EN B2a, b(iii), i.e. Endangered. Further, on the ground assessment is needed at all four sites and may result in the species being assessed as Critically Endangered. Previously the taxon was assessed as VU B1+2b on the basis of a smaller altitudinal and geographical range (Lovett, J. & Clarke, G.P. 1998. Dombeya amaniensis. In: IUCN 2004. Red List of Threatened Species).
    Note
    D. amaniensis is unlikely to be confused with any other species. The shortly peduncled subumbellate inflorescence with only 4–7 very large flowers is unique in African Dombeya, as is the long (1.5–1.6 cm) staminal tube. The record from T 7 is based on Luke (pers. comm) regarding Luke & Luke 4869 & 8745 (EA n.v.) from Udzungwa MNP. Luke also gives a sight record (outside Matundu FR) to support the lower altitudinal range.
