Zanthoxylum davyi, the forest knobwood, is a dioecious species of plant in the family Rutaceae. It is native to the Western Cape, Eastern Cape, KwaZulu-Natal, Mpumalanga and Limpopo provinces of South Africa, western Eswatini and eastern Zimbabwe. It occurs in coastal and mistbelt forests, and grows some 10 to 24 m tall. [1]
Their sturdy, straight trunks are heavily armed with hornlike knobs. [1]
The compound leaves are 5 to 30 cm long. [1]
Birds eat the fruit. [1]
Similar species are the smaller Z. capense which occurs in mostly dryer inland regions, and Z. leprieurii which is native to sand forests of subtropical lowlands.
Sclerophyll is a type of vegetation that has hard leaves, short internodes and leaf orientation parallel or oblique to direct sunlight that are adapted to long periods of dryness and heat that some types of vegetation present. The word comes from the Greek sklēros (hard) and phyllon (leaf). The term was coined by A.F.W. Schimper in 1898, originally as a synonym of xeromorph, but later was changed.
Fynbos is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly coastal and mountainous, with a Mediterranean climate and rainy winters. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting about 80% species of the Cape floral kingdom where nearly 6,000 of them are endemic. This land continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it.
The stone pine, botanical name Pinus pinea, also known as the Italian stone pine, umbrella pine and parasol pine, is a tree from the pine family (Pinaceae). The tree is native to the Mediterranean region, occurring in Southern Europe, The Palestinian Territories, Israel, Lebanon and Syria. It is also naturalized in North Africa, the Canary Islands, South Africa and New South Wales. The species was introduced into North Africa millennia ago, such a long time that it is essentially indistinguishable from being native.
Pinus pinaster, the maritime pine or cluster pine, is a pine native to the Mediterranean region. It is a hard, fast growing pine containing small seeds with large wings.
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903.
Constantiaberg is a large, whalebacked mountain that forms part of the mountainous spine of the Cape Peninsula in Table Mountain National Park, Cape Town, South Africa. It lies about 7 km south of Table Mountain, on the southern side of Constantia Nek. The mountain is 927 m high. It is not known who first ascended the peak.
The Afromontane regions are subregions of the Afrotropical realm, one of the Earth's eight biogeographic realms, covering the plant and animal species found in the mountains of Africa and the southern Arabian Peninsula. The Afromontane regions of Africa are discontinuous, separated from each other by lower-lying areas, and are sometimes referred to as the Afromontane archipelago, as their distribution is analogous to a series of sky islands.
The Cape Floristic Region is a floristic region located near the southern tip of South Africa. It is the only floristic region of the Cape Floristic Kingdom, and includes only one floristic province, known as the Cape Floristic Province.
Gasteria is a genus of succulent plants, native to South Africa.
The wildlife of South Africa consists of the flora and fauna of this country in southern Africa. The country has a range of different habitat types and an ecologically rich and diverse wildlife, vascular plants being particularly abundant, many of them endemic to the country. There are few forested areas, much savanna grassland, semi-arid Karoo vegetation and the fynbos of the Cape Floristic Region. Famed for its national parks and big game, 297 species of mammal have been recorded in South Africa, as well as 858 species of bird and over 20,000 species of vascular plants.
Peninsula Granite Fynbos is an endangered Fynbos vegetation type which is endemic to the city of Cape Town and occurs nowhere else. It is a unique type of tall, dense and diverse scrubland, scattered with trees. It can be found all along the belt of granite that encircles Table Mountain.
Southern Afrotemperate Forest is a kind of tall, shady, multilayered indigenous South African forest. This is the main forest-type in the south-western part of South Africa, naturally extending from the Cape Peninsula in the west, as far as Port Elizabeth in the east. In this range, it usually occurs in small forest pockets, surrounded by fynbos vegetation.
Cecilia is a section of the Table Mountain National Park on the lower eastern slopes of Table Mountain in Cape Town, located just to the south of Kirstenbosch National Botanical Garden. It was previously used for commercial logging and known as Cecilia Forest or Cecilia Plantation, but has now been given protected status and integrated into the National Park.
Mediterranean forests, woodlands, and scrub is a biome defined by the World Wide Fund for Nature. The biome is generally characterized by dry summers and rainy winters, although in some areas rainfall may be uniform. Summers are typically hot in low-lying inland locations but can be cool near colder seas. Winters are typically mild to cool in low-lying locations but can be cold in inland and higher locations. All these ecoregions are highly distinctive, collectively harboring 10% of the Earth's plant species.
Zanthoxylum capense, the small knobwood, is a species of plant in the family Rutaceae. It occurs in the eastern regions of southern Africa, from the vicinity of Knysna, Western Cape to the Zimbabwean granite shield and coastal Mozambique. It tolerates a range of altitudes, from highveld to coastal elevations, but is most prevalent in dry thickets or on rocky slopes and outcrops.
Leucadendron rourkei, the Uniondale conebush, is a flower-bearing shrub belonging to the genus Leucadendron and forms part of the fynbos. The plant is native to the Western Cape and Eastern Cape, South Africa. The plant is rare.
Leucadendron sorocephalodes, the woolly conebush, is a flower-bearing shrub belonging to the genus Leucadendron and forms part of the fynbos. The plant is native to the Western Cape and Eastern Cape where it occurs from the Outeniqua Mountains to the Baviaanskloof Mountains.
Leucadendron eucalyptifolium, the gum-leaved conebush, is a flower-bearing shrub belonging to the genus Leucadendron and forms part of the fynbos.
