Euphorbia pedroi (known in Portuguese as eufórbia-de-gomes-pedro or tabaíba-do-espichel) is a species of flowering plant in the spurge family endemic to the Arrábida Natural Park in Portugal. It is part of section Aphyllis, a mostly African and Macaronesian clade, being the only member of its section native to Europe.[1] Its binomial name is dedicated to José Gomes Pedro (1915-2010) a Portuguese botanist, who studied the flora and vegetation of Arrábida and Mozambique.
Euphorbia pedroi is a sub-succulent shrub that can reach 2m (07feet) tall. Leaves are 25-, green or somewhat glaucous. Cyathium is 2.8- with a 1- peduncle, glabrous or slightly hairy both in the base and peduncle. Fruit is 4.2- yellowish-green or reddish, seeds are reddish brown, 2.8- and somewhat dorsiventrally flattened.[2]
