may be white as in Z. aethiopica, but other species include yellow and pink. Cultivars have a wide variety of other spathe colours including orange and purple. Inside the spathe, the throat may be darkly coloured. The spathe acts to attract pollinators. Flowers: Zantedeschia is monoecious, in which separate male (staminate) and female (pistillate) flowers ("imperfect" or "unisexual" flowers) are carried on the spadix. The flowers are small and non-blooming without a perianth. The male flowers contain two to three stamens fused to form a synandrium, and the female flowers have a single, compound pistil with three fused carpels and three locules. Fruit: Beaked orange or red berries. Taxonomy Zantedeschia is the sole genus in the tribe Zantedeschieae in a 1997 classification of the Araceae. Species Eight species are currently recognized: Zantedeschia aethiopica (L.) Spreng. – giant white arum lily or common arum lily - South Africa, Eswatini, Lesotho Zantedeschia albomaculata (Hook.) Baill. – spotted arum lily - widespread from South Africa north to Nigeria and Tanzania Zantedeschia elliottiana (W.Watson) Engl. – yellow or golden arum lily - Mpumalanga Province of South Africa Zantedeschia jucunda Letty - Leolo Mountains of northern South Africa Zantedeschia odorata P.L.Perry - Western Cape Province Zantedeschia pentlandii (R.Whyte ex W.Watson) Wittm. - Mpumalanga Province of South Africa Zantedeschia rehmannii Engl. – pink arum lily - South Africa, Eswatini, Mozambique Zantedeschia valida (Letty) Y.Singh - KwaZulu-Natal Province of South Africa Etymology The name of the genus was given as a tribute to Italian botanist Giovanni Zantedeschi (1773–1846) by the German botanist Kurt Sprengel (1766–1833). Distribution and habitat All species are endemic to central and southern Africa, from Nigeria to Tanzania and South Africa. Z. aethiopica grows naturally in marshy areas and is only deciduous when water becomes scarce. It grows continuously when watered and fed regularly and can survive periods of minor frosts. Z. aethiopica is a very strong and sturdy plant, being able to grow in many soils and habitats, multiplying by rhizome-offsets; it is naturalised and regarded as a weed throughout much of the world. Z. odorata is a rare species, resembling Z. aethiopica, but deciduous and smelling like freesia, endemic to a few localities in South Africa. Z. albomaculata is a widespread and variable species, growing from South Africa north to Kenya, varying in shades of white to cream and pink to orange-shades. Z. jucunda and Z. pentlandii are rare species with large
