Abstract

Malachra capitata is a small seasonal herb. Flowering occurs during September–October. It is hermaphroditic and self-compatible with a mixed breeding system. The conspicuous floral displays, non-tubular nature of the flower, and the small volume of nectar with high sugar concentration attract bees and butterflies with bees serving as the principal pollinator. The fruit set is 21% in open-pollination mode despite the hectic foraging activity of bees and butterflies. The observed fruit set rate is attributed to the high percentage of flower predation by beetles, and by the nature of soil nutrient/environment requirements. The fruit is a schizocarp with five 1-seeded indehiscent mericarps. New plants arise from seed during the rainy season mostly at parental sites and usually form pure stands; the plants complete their life cycle within six or seven months.
