Female flower of Jatropha gossypiifolia var. gossypiifolia in Chimoio, Mozambique. Note the glandular calyx lobes. A monoecious species with female flowers opening before male flowers. This favours cross-pollination.
Fruit of the Bellyache Bush-- the seeds are considered very toxic. A species of neotropical origin, now planted more widely. Photo from the Colombian Amazon.
