Zantedeschia albomaculata subsp. macrocarpa is characterised by, and differs from subsp. albomaculata, in having triangular-hastate, sparsely speckled leaves, and medium-sized spathes which are straw-coloured and truncate at the apex. Its epithet is derived from the, generally, few and large-sized berries which develop in the withering spathe; these weigh the flaccid peduncle down until it lies on the ground and the seeds germinate.
Perennial herb, up to 0.75 m high. Leaves usually triangular-hastate, sparsely maculate. Berries large, up to 20 mm in diameter. Spathe ± truncate, abruptly acuminate, cream or straw-coloured.
This subspecies is characterized by having the leaves sparsely maculate or sometimes immaculate, triangular hastate, lower lobes bluntly triangular; spathes cream or straw-coloured with limb more or less truncate and terminating abruptly in a subulate tip; fruits usually large, up to 2 cm in diameter, 3 locular, 2-3-ovuled. The flowering period is from October to February with a peak in November.
Occurs on marshy ground beside streams and in grassy vleis.
