Shrub with soft, weak, woody stems; stems and leaves with stinging hairs (CAUTION!); leaves alternate, deeply palmately lobed, the lobes also lobed; sessile glandular region present at the petiole-blade junction; inflorescence cymose, axillary, held above the uppermost leaves; flowers unisexual (plants monoecious); pistillate flowers at the lower cyme branches opening first (protogynous), staminate flowers on subsequent and ultimate cyme branches; flowers white; ovary and immature fruit with longitudinal stripes; fruit an explosively dehiscent capsule.
Listed, as Jatropha aconitifolia, as an important source of pollen and/or nectar for bees (Souza Novello 1981). Cnidoscolus souzae is very similar but can be distinguished by the cluster of finger-like glands at the petiole-blade junction and the larger and more numerous stinging hairs.
