Carissa is a genus of shrubs or small trees native to tropical and subtropical regions of Africa, Australia and Asia. Until recently about 100 species were listed, but most of them have been relegated to the status of synonyms or assigned to other genera, such as Acokanthera . [2] [3]

Description

Different species of Carissa grow as shrubs or trees, attaining respective heights of 2 to 10 m tall. They bear smooth, sharp thorns that often are formidable; they are true botanical thorns, being modified branches, morphologically speaking. The thorns may be simple, as in Carissa spinarum , dichotomously forked as in Carissa bispinosa , or dichotomously branched as in Carissa macrocarpa .

The leaves are a rich, glossy, waxy green, smooth, simple, entire and elliptic to ovate or nearly lanceolate. They are 2–8 cm long, partly depending on the species, and generally are thick and leathery. In suitable climates some species flower through most of the year. The flowers are nearly sessile, 1–5 cm diameter, with a five-lobed white or pink-tinged corolla. They may be solitary or borne in clusters in an umbel or corymb. [4] The flowers of some species some have a fragrance reminiscent of Gardenia , which adds to their popularity as garden plants. The fruit is a plum-like berry in the shape of a prolate spheroid, like that of a rugby ball. In colour they vary according to species. In some species they are red when ripe, whereas others turn a glossy purple-black. Typically they are 1.5–6 cm in length, and usually contain 1-4 flat brown seeds, but up to 16 in some species.

Fruit

The fruit of the carissa is an oblong berry which contains numerous small seeds. [5] The green fruit is poisonous, sometimes dangerously so. The ripe fruit are edible, but may be fairly tart, though some species have fruity flavours with overtones of strawberry or apple. They are rich in Vitamin C, calcium, magnesium and phosphorus.[ citation needed ] The fruit of C. macrocarpa are especially relished[ who? ] and eaten raw or used to make jelly.[ citation needed ] Various birds eat Carissa fruit and distribute the seed.

Carissa carandas is grown in several Asiatic countries for its fruit, which is variously used in cooking and in folk medicine (see article).

Horticulture

Carissa species generally respond well to gardening and are valued in topiary and in forming strong, dense, decorative, thorny, flowering hedges. Some sprawling varieties are useful as ground covers. [6] Carissa species are grown from seed or cuttings and tolerate slight frost.

<span class="mw-page-title-main">Apocynaceae</span> Dogbane and oleander family of flowering plants

Apocynaceae is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here.

<i>Acokanthera oppositifolia</i> Species of plant

Acokanthera oppositifolia is a shrub used as the source of an arrow poison and to coat caltrops made from the sharp fruits of the puncture vine. All plants of the genus Acokanthera contain toxic cardiac glycosides strong enough to cause death. Acokanthera oppositifolia is widespread in southern and central Africa from Cape Province north to The Democratic Republic of the Congo + Tanzania.

<i>Ziziphus mauritiana</i> Species of plant

Ziziphus mauritiana, also known as Indian jujube, Indian plum, Chinese date, Chinese apple, ber, and dunks is a tropical fruit tree species belonging to the family Rhamnaceae. It is often confused with the closely related Chinese jujube, but whereas Z. jujuba prefers temperate climates, Z. mauritiana is tropical to subtropical.

<i>Acokanthera</i> Genus of plants

Acokanthera is a genus of flowering plants in the family Apocynaceae. It comprises 5 species and is generally restricted to Africa, although Acokanthera schimperi also occurs in Yemen. Its sap contains the deadly cardiotoxic glycoside ouabain. The sap is among the most commonly used in arrow poisons, including those used for poaching elephant.

<i>Carissa spinarum</i> Species of shrub

Carissa spinarum, the conkerberry or bush plum, is a large shrub of the dogbane family (Apocynaceae), widely distributed in tropical regions of Africa, Southern Asia, Australia, and various islands of the Indian Ocean. It is most well known in Australia, where it is also called currant bush or, more ambiguously, native currant or even black currant. It is, however, neither closely related to plums (Prunus) nor to true currants (Ribes), which belong to entirely different lineages of eudicots. In India, it is also called wild karanda /wild karavanda, referring to the related karanda. Carissa spinarum is often discussed under its many obsolete synonyms.

<i>Carissa carandas</i> Species of flowering plant

Carissa carandas is a species of flowering shrub in the family Apocynaceae. It produces berry-sized fruits that are commonly used as a condiment in Indian pickles and spices. It is a hardy, drought-tolerant plant that thrives well in a wide range of soils. Common names in English include Bengal currant, Christ's thorn, carandas plum, karonda and karanda.

<i>Carissa macrocarpa</i> Species of shrub

Carissa macrocarpa is a shrub native to tropical and southern Africa. It is commonly known as the Natal plum and, in South Africa, the large num-num. In Zulu, as well as in the Bantu tribes of Uganda, it is called Amathungulu or umThungulu oBomvu. In Afrikaans the fruit is called noem-noem.

<i>Acokanthera schimperi</i> Species of plant

<i>Aspalathus</i> Genus of legumes

Aspalathus is a genus of flowering plants in the family Fabaceae. The yellow flowers and spiny habit of some species have suggested a resemblance to Ulex europaeus, the thorny "English gorse" Accordingly, "Cape Gorse" has been proposed as a common name although the resemblance is largely superficial; for instance, gorse is thorny, whereas Aspalathus species are variously spiny or unarmed. The genus belongs to the subfamily Faboideae. There are over 270 species, mainly endemic to southwestern fynbos regions in South Africa, with over fifty occurring on the Cape Peninsula alone. The species Aspalathus linearis is commercially important, being farmed as the source of Rooibos tea.
