Robinia pseudoacacia, commonly known in its native territory as black locust, is a medium-sized hardwood deciduous tree, belonging to the tribe Robinieae of the legume family Fabaceae. It is native to a few small areas of the United States, but it has been widely planted and naturalized elsewhere in temperate North America, Europe, Southern Africa and Asia and is considered an invasive species in some areas, such as the temperate east coast of Australia where the cultivar 'Frisia'(Golden Robinia) was widely planted as a street tree before being classed as a weed. Another common name is false acacia, a literal translation of the specific name.
Searsia lucida, previously known as Rhus lucida, and commonly known as the varnished kuni-rhus (English) or blinktaaibos (Afrikaans).
Vachellia karroo, (synonym Acacia karroo} commonly known as the sweet thorn, common acacia, Karoo thorn, Cape gum or cockspur thorn, is a species of Vachellia, in the Mimosa sub-family of the Fabaceae or pea family, which is native to southern Africa from southern Angola east to Mozambique, and south to South Africa.
Protea eximia, the broad-leaved sugarbush, is a shrub from South Africa that may become a small tree. It occurs in mountain fynbos on mainly acidic sandy soils; the species was very well known under its old name of Protea latifolia. The flowers have awns that are covered in purple-black velvety hairs, and are contained within a series of rings of involucral bracts that have the appearance of petals. The fruit is a densely hairy nut, many of which are inserted on a woody base. The flowers are borne terminally on long shoots, and have a tendency to become very untidy as they age.
Gymnosporia is an Old World genus of plants, that comprise suffrutices, shrubs and trees. It was formerly considered congeneric with Maytenus, but more recent investigations separated it based on the presence of achyblasts and spines, alternate leaves or fascicles of leaves, an inflorescence that forms a dichasium, mostly unisexual flowers, and fruit forming a dehiscent capsule, with an aril on the seed. It is dioecious, with male and female flowers on separate plants.
Gymnosporia heterophylla, the common spike-thorn, is a small, hardy, deciduous African tree up to 5m tall, occurring in rocky places with a wide distribution from Ethiopia, the Sudan and the Congo, south to the Cape Province and west to Angola and Namibia, as well as the neighbouring islands of Madagascar and Saint Helena, with a closely related species from Mauritius.
In plant morphology, thorns, spines, and prickles, and in general spinose structures, are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically deterring animals from eating the plant material.
Euclea crispa, commonly known as the blue guarri, is an Afrotropical plant species of the family Ebenaceae. The hardy and evergreen plants may form a dense stand of shrubs, or grow to tree size. It is widespread and common in the interior regions of southern Africa, and occurs northward to the tropics. Though some are present near the South African south and east coasts, they generally occur at middle to high altitudes. It is readily recognizable from its much-branched structure and dull bluish foliage colour. Those bearing lanceolate leaves may however resemble the Wild olive, another common species of the interior plateaus.
