Euphorbia pedroi is a sub-succulent shrub that can reach 2 m (6.6 ft) tall.[1] Leaves are 25 mm–60 mm × 4 mm–10 mm (0.98 in–2.36 in × 0.16 in–0.39 in), green or somewhat glaucous. Cyathium is 2.8–4 mm (0.11–0.16 in) with a 1–3 mm (0.039–0.118 in) peduncle, glabrous or slightly hairy both in the base and peduncle. Fruit is 4.2 mm–5 mm × 5.8 mm–7.2 mm (0.17 in–0.20 in × 0.23 in–0.28 in) yellowish-green or reddish, seeds are reddish brown, 2.8 mm–3.2 mm × 2 mm–2.3 mm (0.110 in–0.126 in × 0.079 in–0.091 in) and somewhat dorsiventrally flatened.[3]

Euphorbia pedroi is native to the Arrábida Natural Park, specifically between Cabo Espichel and Sesimbra on the Setúbal Peninsula, in the Atlantic coast. It is found on slopes of south-facing limestone cliffs on incipient soils or rock cracks subjected to regular mist and strong winds.[1][2]
