Type
Type: Uganda, Kigezi District: Bukiribiri, Bufumbira, Purseglove 2112 (EA!, holo. K!, iso.)
Morphology General Habit
Perennial semi-creeping herb, 15–75 cm tall, rooting at the nodes
Morphology Stem
Stems 4-sided, glabrous to slightly hairy at base to increasingly pubescent towards the inflorescence
Morphology Leaves
Leaves petiolate; blades lanceolate-elliptic to ovate, 0.5–11 cm long, margins serrate (up to 9 teeth per side) to sometimes slightly double serrate (especially on the 3rd and 6th teeth from base), apex acute, base cuneate, slightly pubescent to pubescent, upper surface dirty green, veins prominent, lower surface more pubescent and lighter green than upper, leaves towards the base as stems ascend sometimes tinged with pink; petioles 1–2 cm long
Morphology Reproductive morphology Inflorescences
Inflorescence up to 11 cm long, the space between nodes so short that the verticils merge together at the tip; bracts more pointed than the leaves, ± 40 × 11 mm, entire or slightly serrate, petioles up to 3.5 mm long
Morphology Reproductive morphology Flowers Calyx
Calyx actinomorphic, sometimes weakly 2-lipped, 4.5–6.5 mm long; lobes lanceolate to deltoid, pubescent, curving inwards at maturity
Morphology Reproductive morphology Flowers Corolla
Corolla white, 5.5–11 mm long; tube 4–6 mm long, expanding at the base then closing over the nutlets with a thick mat of hairs at the base just above nutlets; posterior lip slightly emarginate, the anterior lip with 3 lobes the median emarginate, 3–5 mm long
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens exserted
Morphology Reproductive morphology Fruits
Nutlets dark brown, oblong, 2 mm long, with reticulate ridges and further ridges within with tiny matted hairs inside the ridged hollows
Figures

Ecology
Forest floor along deep shady paths, wet places in open grazed land or swampy pockets; 1600–2650 m
Conservation
Least concern; probably not threatened
Note
Robyns, loc. cit. (1943), rightly recognised the species found in the eastern part of Congo-Kinshasa and western Uganda as a species clearly distinct from A. integrifolia ( A. remota), but thought it was the same as a plant from Kilimanjaro attributed to forma alba by Gürke in P.O.A. C: 342 (1895). The type of that form no longer exists, but all the material seen from Kilimanjaro, including material distributed from Berlin labelled “var. alba”, is unmistakably A. integrifolia. A. leucantha is now known to occur in western Ethiopia as well.
