Diagnostic Description

Zantedeschia jucunda is most nearly related to Z. pentlandii and Z. albomaculata. It differs from the former in having triangular-hastate, copiously spotted leaves with upwardly spreading basal lobes and an acute apex, while the spathe is more cup-shaped, a deeper yellow without and within, where it is also slightly rugose, and the limb more spreading and tapering to a subulate tip; whereas Z. pentlandii has immaculate (or rarely maculate), oblong- lanceolate leaves with short rounded basal lobes, the spathe regularly funnel-shaped, limb erect, lighter in colour, greenish outside, terminating abruptly in a subulate tip. From the form of Z. albomaculata subsp. albomaculata occurring in the eastern Transvaal, Z. jucunda differs in its consistently brilliant yellow spathes, whereas the spathes of Z. albomaculata may be white, cream or pale-yellow with an occasional coral-pink variation.
