Euphorbia paralias, the sea spurge, is a species of flowering plant in the family Euphorbiaceae, native to Europe, northern Africa and western Asia.^[1]

The species is widely naturalised in Australia.^[2] It invades coastal areas, displacing local species and colonising open sand areas favoured by certain nesting birds.^[3] Major eradication programmes have been undertaken in some areas, for example by Sea Spurge Remote Area Teams in Tasmania, with great success.^[4]

Description[]

It is an erect, glaucous, perennial plant growing up to 70 cm tall. The plant has many stems, dividing into 3-5 fertile branches, each branching further. The cauline leaves (arising from the stem, without stalk) are crowded, overlapping, elliptic-ovate (ovate toward the top of the stems), fleshy and 5 to 20 mm long. Leaves on fertile branches are circular-rhombic or reniform. Flower head on a solitary cyathia, found in upper forks or at the apex, surrounded by bell-shaped bracts. Female flowers are with styles that divide into two short stigmas, flowering September-May. Fruit is a capsule flattened from above or nearly spherical, deep furrows, wrinkled on keels. Seeds ovoid, pale-grey and smooth. There is a kidney-shaped fleshy outgrowth from the seed coat.^[5]^[2]
