Information
Fleshy glabrous herb with long decumbent stems; stems branched, the branches smooth, flattened and deeply grooved one face. Upper stems mostly pale, lower and rhizomes darker, apparently with a reddish dye. Leaves 0.7–2.3 x 0.3–1 cm., oblong-elliptic to oblong, rounded to subacute at apex, usually ± mucronate, narrowed at the base but sessile on to the petiole sheath; stipule sheath up to 8 mm. long with 1 to several short lobes scarcely 0.5 mm. long. Calyx tube 2 mm. long, the limb ± 2 mm. long, erose or with triangular lobes ± 1 mm. long and wide. Corolla white or pinkish; tube 4–5 mm. long; lobes 3–4 x 1.5–1.7 mm., oblong-elliptic, ± oblique at apex. Long-styled flowers with anthers 1.7 mm. long and about 2/3 exserted; style exserted 2.5 mm. the stigmatic lobes 1.2 mm. long. Short-styled flowers with anthers 2.4 mm. long, versatile, the filaments exserted 1.5 cm.; tips of stigmatic lobes exserted for about 1 mm. Fruits 3–6 x 2–4 mm.; seeds c. 3.5 mm. long.

Distribution (external)
S. Africa (NE. Cape and Natal)
Notes
I referred Tanzanian material of the genus to Phylohydrax madagascariensis (Willd. ex Roem. & Schultes) Puff; there appear to be foliage differences. The relationship between the two species will remain doubtful until better material of both, particularly fruits and seeds, are available. The Asiatic species Hydrophylax maritima L.f. is very distinct.
