SPECIES PLANTARUM — FLORA OF THE WORLD (2002)
sheaths closed, later split, base green; auricles ±absent. Lower bract leaf-like, c. 1.5–3.5 cm
long, usually exceeding inflorescence. Inflorescence usually congested, a globose head of
1–3 (–12) usually 6–12-flowered clusters, or 1–3 clusters shortly pedunculate. Tepals
subequal; outer tepals lanceolate, carinate, acuminate-aristate, c. 3.7–4.2 mm long, greenish
or pale brown to castaneous-brown, with central band often greenish, ±scabrid; inner tepals
ovate-lanceolate, ±obtuse, sometimes shorter than the outer; margins membranous, broad.
Stamens 6; anthers 0.5–0.7 mm long; filaments 0.6–0.8 mm long; style 0.4–0.8 mm long;
stigmas to c. 1 mm long, suberect. Capsule ±ovoid, trigonous, subacute, apiculate, c. 2.5–3.0 mm
long, shorter than perianth, pale greenish brown to castaneous; mucro to c. 0.2 mm long.
Seeds ovoid, pale brown, 0.4–0.5 × c. 0.3 mm, faintly reticulate; apex whitish apiculate;
appendages absent.
Restricted to S Cape, South Africa, with the most common occurrence in the vicinity of Port
Elizabeth. Introduced in New Zealand. 27: CPP. 51: nzn. Wet sandy places, seepage areas,
along streams. Map 192 (secondary distribution not shown).

The relatively high variability, occasional sterility and the intermediate character supports
the hypothesis expressed by Obermeyer, in A.A.Obermeyer, J.Lewis & R.B.Faden, Fl. S.
Afr. 4/2: 85 (1985), that J. sonderianus may be of hybrid origin, of J. dregeanus and
J. lomatophyllus parentage. The sample T.C.E.Fries & al. 210 is closer to J. lomatophyllus
while W.J.Burchell 4386 is similar to typical J. dregeanus. The problem requires a field study.
