Isolepis antarctica (L.) Roem. & Schult.

Isolepis antarctica is an annual of about 80 to 200 mm tall, with numerous straw-coloured and dark red spikelets that consist of an indeterminate rachilla with many, spirally arranged glumes, with each glume subtending a bisexual flower. Its subtending glumes develop slowly and older glumes grow into a bonnet-like shape, protecting the fruit. It is widely distributed in damp flats and slopes up to 800 m altitude, from the Cape Peninsula to Langeberg Mountains in the Western Cape. It flowers between October to November.

Isolepis hystrix (Thunb.) Nees

Isolepis hystrix is a small, densely tufted, annual species about 20 to 100 mm tall, with green spikelets. It is usually found in damp flats, and sometimes at altitudes of about 1 600 m. It is widely distributed from Namaqualand to the Cape Peninsula. This species flowers between August and November.

Isolepis striata (Nees) Kunth

Isolepis striata extends from Namaqualand to Riviersonderend to Uitenhage in the Eastern Cape, growing in pools at lower altitudes. It is a branched aquatic perennial with green or reddish terminal spikelets and glumes from 3.5 to 4.5 mm long. There are three involucral bracts that are shorter than the spikelets. The species flowers between August and December.

albomaculata (Hook.) Baill.
Common names: Arrow-leaved arum, spotted-leaved arum (Eng.); kleinvarkoor, witvlekvarkoor (Afr.); mohalalitoe (South Sotho); intebe (Xhosa, Zulu), ilabatheka-elimhlophe (Zulu), ilabatheka-omhlophe (Zulu). These are deciduous, medium to tall plants up to 0.7 m high, growing in small clumps. They have oblong or triangular arrow-shaped leaves, often speckled with white spots. Spathes are cylindrical, white, cream or pale yellow and frequently dark purple at the base within.

subsp. albomaculata
Leaves oblong, spathe tapering to apex, berries many, medium-sized, up to 18 mm in diameter. It flowers October to April. The subspecies occurs in the Eastern Cape, KwaZulu-Natal, Lesotho, Free State, Swaziland, Mpumalanga and Limpopo. It also extends into Zimbabwe, Malawi, Zambia, Angola and Tanzania. It is found along rocky hillsides, forest margins and stream banks.

subsp. macrocarpa (Engl.) Letty
Leaves triangular, spathe shortened at apex, berries few, large, mostly close to 20 mm in diameter. It flowers from November to April with a peak in December. The subspecies occurs in KwaZulu-Natal, Lesotho, Free State, Swaziland, Mpumalanga and Gauteng. It grows in grassy vleis and marshy ground beside streams.

Zantedeschia odorata P.L.Perry
These are deciduous, medium to tall plants up to 0.75 m high. Their leaves are broadly ovate and not speckled. Spathes are cylindrical and white. They flower in late July and August.
Z. odorata is restricted to an area known as Klip Koppies at Nieuwoudtville in the Northern Cape. The outcrops are formed by large dolerite boulders which break down to form a red clay soil which retains water well in the rainy season. The plants grow in crevices between the boulders, where at least the lower part of the plant is in cool shade. The roots are in seasonally very wet soil or sometimes in standing water.

Zantedeschia jucunda Letty
Common name: magapule (Pedi)
These are deciduous, medium to tall plants, up to 0,8 m high, growing solitary or in small clumps. Their leaves are triangular-hastate, deep green and speckled with white spots. The spathe is a cup-shaped funnel, deep or cream-yellow and dark purple at the base within. They flower from November to January.

Z. jucunda is confined to the summit of the Leolo Mountains in the Sekhukuneland Centre of Floristic Endemism. This species grows on grassy slopes, among rocks in full sun.

Zantedeschia valida (Letty) Y.Singh
These are deciduous, robust plants, up to 0.75 m tall. Leaves broadly ovate, plain, not speckled or very speckled with white spots. The spathe is a cup-shaped funnel dark purple at the base within. They flower from October to March with the peak in November.

The species is restricted to the region bordered by the Biggarsberg, Giants Castle and Collin's Pass in KwaZulu-Natal. Plants grow among rocks on the mountains in clefts and on foothills, as well as on the banks of streams and in vleis.
