Euphorbia leuconeura

Euphorbia leuconeura is a species of flowering plant in the family Euphorbiaceae. Its common name is Madagascar jewel. It is endemic to Madagascar where its natural habitat is forest undergrowth in rocky areas. It can grow to a height of, as a branching small tree, and propagates by shooting its seeds several feet into the air. It is threatened by habitat loss.

Taxonomy

The specific epithet leuconeura is derived from the two ancient greek words, meaning "bright, white", and, meaning "nerve".

Cultivation

The Madagascar Jewel is grown as a houseplant for its attractive foliage: dark green leaves, with white veins when young. Unlike many succulents, E. leuconeura is less susceptible to overwatering. It grows best in partial shade but tolerates full shade and is relatively easy to care for providing it is not exposed to cold drafts.

Toxicity

When damaged, the plant secretes a white fluid which is toxic and can cause severe skin irritation. This is typical of most Euphorbia species.
