Euphorbia paralias | |
Euphorbia paralias, the Sea Spurge, [1] is a species of flowering plant in the family Euphorbiaceae, native to Europe, northern Africa and western Asia. [2]
The species is widely naturalised in Australia. [3] It invades coastal areas, displacing local species and colonising open sand areas favoured by certain nesting birds. [4] Major eradication programs have been undertaken in some areas, for example by Sea Spurge Remote Area Teams in Tasmania, with great success. [5]
E. paralias is an erect, glaucous, perennial plant, growing up to 70 centimetres (28 in) tall. It has many stems, dividing into 3–5 fertile branches, each branching further. The cauline leaves (arising from the stem, without a stalk) are crowded, overlapping, elliptic-ovate (ovate toward the top of the stems), fleshy and 5–20 millimetres (0.2–0.8 in) long. Leaves on fertile branches are circular-rhombic or reniform. The flower head is on a solitary cyathium, found in upper forks or at the apex, surrounded by bell-shaped bracts. Female flowers have styles that divide into two short stigmas, flowering from September to May. The fruit is a capsule, flattened from above or nearly spherical, with deep furrows, and wrinkled on keels. Seeds are ovoid, pale-grey and smooth. There is a kidney-shaped fleshy outgrowth from the seed coat. [6] [3]
E. paralias inhabits sandy sea-shores. [7]

Native to central and southern Europe and west Asia, in some parts of North America it is an extremely invasive species.
Acalypha rhomboidea is a plant in the spurge family, Euphorbiaceae.
Crupina vulgaris is a species of flowering plant in the family Asteraceae. Its common names include common crupina, bearded-creeper, false saw-wort, and starry scabious. It is native to parts of Europe, Asia, and North Africa, and it is known elsewhere as an introduced species and often a noxious weed.
Euphorbia misera is a semi-succulent shrub in the genus Euphorbia commonly known as the cliff spurge or coast spurge. A drought-deciduous shrub, it is typically found as a gnarled, straggly plant occupying seashore bluffs, hills and deserts. Like other members of its genus, it has a milky sap, which can be found exuding out of the light gray bark when damaged. The alternately-arranged leaves are round and folded in the middle, with small hairs on them. The "flowers" can be found blooming year-round, and are colored maroon or yellow in the center with 5 white to light-yellow petal-like appendages attached outside. This species is native to the Baja California peninsula and Sonora in Mexico, and the coast of Southern California in the United States, where it is a rare species. It is threatened in some localities by the development of its coastal habitat, which tends to be prime locations for high-end residential and commercial developments.
Euphorbia balsamifera is a flowering plant in the spurge family Euphorbiaceae. It is distributed in the Canary Islands and the western Sahara. It is the vegetable symbol of the island of Lanzarote. Euphorbia adenensis has been treated as a subspecies of this species.

Varronia curassavica, synonym Cordia curassavica, commonly known as black sage or wild sage, is a species of flowering plant in the borage family, Boraginaceae. It is sometimes called tropical black sage to distinguish it from another unrelated species named black sage, Salvia mellifera. It is native to tropical America but has also been widely introduced to Southeast Asia and the tropical Pacific region, where it is an invasive weed. The specific epithet is a latinised form of Curaçao, an island in the southern Caribbean Sea region and the locality of the type collection.
Euphorbia royleana is a species of flowering plant in the family Euphorbiaceae. It is also known as Sullu spurge, and Royle's spurge. It is a succulent and almost cactus like in appearance although unrelated. It grows right across the Himalaya mountains from Pakistan, India, Bhutan, Myanmar, Nepal to western China. It prefers dry and rocky slopes between 1000 and 1500 meters, but has been found up to 2000 meters. Flowering and fruiting is in spring to early summer (March–July) and seeding is in June–October. It is used as a hedging plant in northern India and has medicinal uses.
