Names
Oxygonum delagoënse Kuntze [family POLYGONACEAE], Rev. Gen. Pl. 3: 268 (1898); F.T.A. 6 (1): 100 (1909); Fl. Cap. 5 (1): 461 (1912). Type: Portuguese East Africa, Delagoa Bay, Kuntze (NY, holo., K, iso.!)
Information
An erect or ascending herb. Stems up to 1 m. tall, glabrous to pubescent, reddish-brown. Ocreae 4–6 mm. long, pubescent, membranous, truncate, with a terminal fringe of ± light-brown, erect-patent setae 4–5 mm. long. Leaves 2–8 cm. long, often less than 8 mm. broad but up to 1.8 cm., basally decurrent, narrowly elliptic-lanceolate or linear-lanceolate to lanceolate or lanceolate-elliptic, apically acute, mucronate, entire, the margins sinuous, or with 1–3 pairs of forward-directed lobes, sometimes very asymmetrical, puberulent or not on the midrib. Inflorescence elongated, probably up to 30 cm. Bracts 4 mm. long, 1–2.5 (–3) cm. apart, pubescent, with or (commonly) without a fringe of setae. Pedicels 2–4 (–6) together, not exceeding the bracts by more than 3 mm., erect, glabrous or puberulous. Flowers white, 4.75–6 mm. long. Tepals 3–3.75 mm. long. Short styles probably 1.5–2.5 mm. long, free to the base or up to 1 mm. connate. Filaments 1–4.5 mm. long. Fruit 5 (–6) mm. long, pubescent, otherwise smooth, conical, usually armed a little above the base with three small (sometimes scarcely perceptible) ± retrorse teeth or protuberances at the angles.
Range
DISTR. T?6 also elsewhere in southern and particularly in coastal SE. Africa
Distribution
TANGANYIKA Probably Dar es Salaam, Vaughan 2368!
Distribution (external)
Portuguese East Africa
Bechuanaland
Notes
The above record is based on a specimen in the British Museum herbarium which is probably this species, but only vegetative characters are available for identification owing to the absence of all but very immature fruit.
