Information
A prostrate herb diffusely branched from the base, sometimes rooting at the nodes, more or less pilose (often bifariously on the branches); branches usually 9–12 in. long, herbaceous or sometimes becoming almost woody, hollow. Leaves petiolate, ovate, elliptic-ovate or rarely suborbicular, 1/2–1 1/4 in. long, 1/2– 3/4 in. broad (rarely 1 1/2–2 in. long, 1–1 1/4 in. broad), obtuse or subacute, rounded, slightly cordate, truncate or somewhat cuneate at the base, crenate-serrate (often coarsely) or crenate, more or less pilose on both sides or sometimes almost glabrous; petiole usually about 3 (rarely up to 6) lin. long. Racemes 1–2 1/2 in. long, often 2- (sometimes up to 5-) flowered; bracts linear-oblong, 1 3/4–3 lin. long, obtuse; pedicels 2–4 lin. long. Calyx 2–2 1/2 lin. long in flower, 3–3 1/2 lin. long in fruit; segments oblong, elliptic-oblong or spathulate-elliptic, obtuse, ciliate and sometimes pilose inside and outside. Corolla 3–3 1/2 lin. long, cobalt-blue (pinky-white, Johnston). Style 1–1 1/2 lin. long. Capsule obovate, compressed, pilose or rarely glabrous, 1/2– 2/3 lin. shorter than the calyx.

Notes
We have followed Engler in uniting V. petitiana and V. africana with V. abyssinica. Though this seems the best course, it should be d that some slight differences can be detected between the material from the Cameroons (V. africana) and that from Eastern Africa. In the former the petioles are usually longer, the leaves have smaller teeth, the flowers are said by Johnston to be pinky-white, and the style is shorter. Moreover, two of the Abyssinian specimens (Schimper, 1154) named V. petitiana at Kew, differ from the rest of the East African material in having shorter petioles, suborbicular crenate leaves, and broader calyx-segments. These hardly agree with Richard's description of V. petitiana. An examination of the types of V. abyssinica and V. petitiana, which are not accessible to us, might suggest that the plant from the Cameroons and the doubtful Abyssinian one should constitute two varieties of V. abyssinica .
