Lycium ferocissimum, the African boxthorn or boxthorn, is a shrub in the nightshade family (Solanaceae) indigenous to South Africa.
The species is native to the Western Cape and Eastern Cape provinces in South Africa, where it tends to occur in sands along the southern coast. It has also been recorded in the Free State, but these may represent introductions. It has been widely introduced in South Africa and elsewhere in Africa, as far north as Morocco. [1]
It has become naturalised in Australia and New Zealand. [2] It is listed in Australia's Weed of National Significance list and is a declared noxious weed in the United States. [2] [3]
African boxthorn is a large shrub which grows up to 5 metres (16 ft) high and is covered in spines. The spines are of randomly varying lengths along the branch and, unlike most other species of Lycium (except for Lycium amoenum ), they take the form of stout "peg-thorns".
The leaves are oval in shape and are 10–40 millimetres (0.39–1.57 in) long and 4–10 millimetres (0.16–0.39 in) in width. The broadly obovate or elliptical shape of the leaves can serve to distinguish this species from many other similar species of Lycium, which tend to have narrower leaves.
The solitary flowers emerge from the leaf axils. The corolla is funnel-shaped with large, reflexed, pale purple lobes (petals). The calyx is tubular and encloses most of the corolla (a character shared with Lycium pumilum ). This latter character, the calyx that is at least two thirds of the length of the corolla, serves to distinguish this species from many of its relatives. [1]
The species was first formally described in 1854 by British botanist John Miers in the Annals and Magazine of Natural History . His description was based on plant material collected from Uitenhage in South Africa. [4]
Lycium is a genus of flowering plants in the nightshade family, Solanaceae. The genus has a disjunct distribution around the globe, with species occurring on most continents in temperate and subtropical regions. South America has the most species, followed by North America and southern Africa. There are several scattered across Europe and Asia, and one is native to Australia. Common English names for plants of this genus include box-thorn, wolfberry, and desert-thorn. There are about 70 to 80 species.
Lycium barbarum is a shrub native to China, with present-day range across Asia and southeast Europe. It is one of two species of boxthorn in the family Solanaceae from which the goji berry or wolfberry is harvested, the other being Lycium chinense.
Centaurea calcitrapa is a species of flowering plant known by several common names, including red star-thistle and purple star thistle. It is native to Europe but is rarely found there, it is known across the globe as an introduced species and often a noxious weed. The species name calcitrapa comes from the word caltrop, a type of weapon covered in sharp spikes.
Lycium chinense is one of two species of boxthorn shrub in the family Solanaceae. Along with Lycium barbarum, it produces the goji berry ("wolfberry"). Two varieties are recognized, L. chinense var. chinense and L. chinense var. potaninii. It is also known as Chinese boxthorn, Chinese matrimony-vine, Chinese teaplant, Chinese wolfberry, wolfberry, and Chinese desert-thorn.
Cestrum nocturnum, the lady of the night, night-blooming jasmine, night-blooming jessamine, night-scented jessamine, night-scented cestrum or poisonberry, is a species of plant in the potato family Solanaceae. It is native to the West Indies, but naturalized in South Asia.
Olea europaea subsp. cuspidata is a subspecies of the well-known olive tree, which until recently was considered a separate species and is still mentioned as such in many sources. Native to northeast of Africa and the drier parts of subtropical Asia, it has various common names, including wild olive, African olive, brown olive and Indian olive.
Lycium andersonii is a species of flowering plant in the nightshade family, Solanaceae. Its common names include water-jacket, redberry desert-thorn, Anderson thornbush, Anderson's desert thorn, Anderson boxthorn, Anderson lycium, Anderson wolfberry, and squawberry.
Senecio angulatus, also known as creeping groundsel and Cape ivy, is a succulent flowering plant in the family Asteraceae that is native to South Africa. Cape ivy is a scrambling herb that can become an aggressive weed once established, making it an invasive species. It is grown as an ornamental plant for its satiny foliage and sweet-scented flowers.
Iochroma arborescens is a species of flowering plant in the genus Iochroma, belonging to the nightshade family Solanaceae. Formerly it was considered the single species in the monotypic genus Acnistus. Common names include gallinero, mata-gallina, fruta-de-sabiá, hollowheart, wild tobacco, siyou, bastard sirio, galán arbóreo, tabaco de monte, nigüito, marieneira, güitite, and tabak djab.
Lycium fremontii is a species of flowering plant in the nightshade family, Solanaceae, that is native to northwestern Mexico and the southernmost mountains and deserts of California and Arizona in the United States. It often grows in areas with alkaline soils, such as alkali flats.
Coprosma quadrifida is a dioecious shrub of the family Rubiaceae native to southeastern Australia. First described as Canthium quadrifidum by Labillardiere, it was given its current name by B. L. Robinson in 1910. Typically found at damp sites within woodlands, Eucalyptus forests or cool-temperate rainforests, it prefers sheltered slopes or sites near water sources. They are able to withstand frost and are salt tolerant. The species is also known as the Prickly Currant Bush.
Lycium afrum, the kraal honey thorn is a shrub in the potato family (Solanaceae), indigenous to the Western Cape Province, South Africa.
The Solanaceae, or the nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
Lycium australe, the Australian boxthorn, is a native Australian plant with large sharp woody spines, small leaves and very small berries. It is closely related to Lycium ferocissimum, which is listed as an invasive weed in Australia, New Zealand and Cyprus.
Lycium ferocissimum, the African boxthorn, is a species of shrub in the family Solanaceae (nightshades). They have a self-supporting growth form. Individuals can grow to 1.5 m.
Lycium oxycarpum is a shrub in the nightshade family (Solanaceae) indigenous to the Karoo regions of South Africa.
Lycium horridum is a shrub in the nightshade family (Solanaceae) indigenous to South Africa as well as southern Namibia and Botswana.
Lycium pumilum is a shrub in the nightshade family (Solanaceae) indigenous to South Africa and Namibia.
Lycium cinereum is a shrub in the nightshade family (Solanaceae) indigenous to southern Africa. It is widespread across South Africa, as well as southern Namibia and Botswana.
Lycium tenue is a shrub in the nightshade family (Solanaceae) indigenous to South Africa.
