LEAVES: White veins and white needle-spines make the deeply lobed, dark green leaves very conspicuous. The needles deliver stinging chemicals into the skin if one is careless enough to brush against them.

RANGE: In Arizona this plant is restricted to lower canyons and slopes of the Sky Island Mountains in the southeast. Ranges into Mexico.

PERENNIAL: Above ground portions are mostly herbaceous and mostly less than a meter tall.

FLOWERS: Bright white flowers appear after summer rains.

FRUIT: Like most euphorbs, the capsules are three-parted, but these are also set with stingin hairs.
