Ardisiandra stolzii Weim. [family PRIMULACEAE], in Svensk Bot. Tidskr. 30 : 44 (1936). Type : Tanganyika, Rungwe District, Kyimbila, Stolz 167 (BM, UPS, iso. !)
Information
Stems slender, reddish, prostrate, up to 45 cm. long, rooting at the nodes; internodes 5–30 mm. long. Leaves numerous; petiole slender, pubescent, up to 4 cm. long; lamina orbicular, up to 40 × 40 mm., sparsely pubescent on both surfaces, obtuse, basally cordate, 7–9-crenate, the crenations with a few short broad acute teeth. Racemes 1–6-flowered; axes up to 10 mm.; peduncles up to 10 mm.; pedicels filiform, up to 20 mm. long; bracts linear-lanceolate, 3–4 mm. long. Calyx-segments narrowly ovate, pubescent, basally rounded, acute, ciliate, slightly accrescent, at anthesis about half as long as the corolla. Corolla white or pale mauve, up to 8 mm. long; lobes 2–3 mm. long, glabrous; apex rounded or emarginate. Filaments about 0.6 mm. long; anthers about 1.3 mm. long. Capsule globose, about 4–5 mm. in diameter, indehiscent, with a thin transparent pericarp through which can be seen the swollen whitish placenta and black seeds. Seeds about 1.2 mm. long. Fig. 1/1–11, p. 3.
Range
DISTR. U2; K3, 4, 7; T2, 3, 7, 8 ; mountains of eastern Africa from Uganda and the adjacent parts of the Belgian Congo to Southern Rhodesia (Inyanga).
Altitude range
1800–3600 m.

Notes
This species is very similar indeed to A. sibthorpioïdes and in the absence of fruits certain identification is almost impossible. The primary lobes of the leaf-margin in the present species seem to be more (7–9) than in A. sibthorpioïdes (5–7), but it is often difficult to distinguish between the primary lobes and the secondary toothing and determine the number of the former.
