Selenicereus undatus, the white-fleshed pitahaya , is a species of the genus Selenicereus (formerly Hylocereus) in the family Cactaceae [2] and is the most cultivated species in the genus. It is used both as an ornamental vine and as a fruit crop - the pitahaya or dragon fruit. [3]

Contents

Like all true cacti, the genus originates in the Americas,S. undatus is originates from Mexico to Honduras; [4] it may be a hybrid. It is most frequently attributed to the island of Martinique in the West Indies [5]

Plant

Dragonfruit stems are scandent (climbing habit), creeping, sprawling or clambering, and branch profusely. There can be four to seven of them, between 5 and 10 m (16 and 33 ft)or longer, with joints from 30 to 120 cm (12 to 47 in) or longer, and 10 to 12 cm (3.9 to 4.7 in) thick; with generally three ribs; margins are corneous (horn-like) with age, and undulate. [3]

Areoles, that is, the small area bearing spines or hairs on a cactus, are 2 mm (0.079 in) across with internodes 1 to 4 cm (0.39 to 1.57 in). Spines on the adult branches are 1 to 4 mm (0.039 to 0.157 in) long, being acicular (needle-like) to almost conical, and grayish brown to black in colour and spreading, with a deep green epidermis. [3]

Flowers

The scented, nocturnal flowers are 25 to 30 cm (9.8 to 11.8 in) long, 15 to 17 cm (5.9 to 6.7 in) wide with the pericarpel 2.5 to 5 cm (0.98 to 1.97 in) long, about 2.5 cm (0.98 in) thick, bracteoles ovate, acute, to 2.5 to less than 4 cm (1.6 in) long; receptacle about 3 cm (1.2 in) thick, bracteoles are linear-lanceolate, 3 to 8 cm (1.2 to 3.1 in) long; outer tepals lanceolate-linear to linear, acuminate (tapering to a point), being 10 to 15 cm (3.9 to 5.9 in) long, 10 to 15 mm (0.39 to 0.59 in) wide and mucronate (ending in a short sharp point). Their colour is greenish-yellow or whitish, rarely rose-tinged; These outer tepals, or sepals are about 65 in number, and bring the flower to a total width of up to fourteen inches (35 centimeters). [6] inner tepals are lanceolate (tapering to a point at the tip) to oblanceolate (i.e. more pointed at the base), up to 10 to 15 cm (3.9 to 5.9 in) long about 40 mm (1.6 in) wide at widest point, and mucronate, unbroken, sharp to acuminate (pointed), and white.

Stamens 5 to 10 cm (2.0 to 3.9 in) long, are declinate, inserted in one continuous zone from throat to 35 mm (1.4 in) above the pericarpel and cream. The style (bearing the stigma) to 17, they are 5 to 24.5 cm (2.0 to 9.6 in) long, stout, 6 to 8 mm (0.24 to 0.31 in) thick, cream, and up to 26 stigma lobes, they can be whole or sometimes split at the top, cream, about 25 mm (0.98 in) long. Nectar chambers are 30 mm (1.2 in) long. [3]

Fruit

The fruit is oblong to oval, 6 to 12 cm (2.4 to 4.7 in) long, 4 to 9 cm (1.6 to 3.5 in) thick, red with large bracteoles, with white, or more uncommonly, pink pulp and edible black seeds. [3]

Habitat

Selenicereus undatus is lithophytic or hemiepiphytic. It is widely distributed through the tropics in cultivation. It is a sprawling or vining, terrestrial or epiphytic cactus. They climb by use of aerial roots and can reach a height of 10 meters (32.8 feet) or more growing on rocks and trees.

Systematics

This species is closely related to S. ocamponis and S. escuintlensis. Selenicereus undatus was described by (Haw.) Britton & Rose and published in Flora of Bermuda 256. 1918. In 2017, D. R. Hunt groups the genus Hylocereus within the genus Selenicereus. This has been supported by a phylogenetic analysis of the Hylocereeae tribe (Korotkova, et al., 2017), therefore this species is consigned under the name Selenicereus undatus [7]

Taxonomy

The species's epithet undatus in Latin means "wavy" from unda "wave", [8] referring to the wavy edges of its branches' ribs.

<span class="mw-page-title-main">Night-blooming cereus</span> Common name for several species of cactus

Night-blooming cereus is the common name referring to a large number of flowering ceroid cacti that bloom at night. The flowers are short lived, and some of these species, such as Selenicereus grandiflorus, bloom only once a year, for a single night, though most put out multiple flowers over a period of several weeks, each of which opens for only a single night. Other names for one or more cacti with this habit are princess of the night, Honolulu queen, Christ in the manger, dama de noche, and queen of the night.

<i>Epiphyllum</i> Genus of cacti

Epiphyllum is a genus of epiphytic plants in the cactus family (Cactaceae), native to Central America and South America. Common names for these species include climbing cacti, orchid cacti and leaf cacti, though the latter also refers to the genus Pereskia.

<span class="mw-page-title-main">Ceroid cactus</span> Any cactus with an elongated body

The term ceroid cactus is used to describe any of the species of cacti with very elongated bodies, including columnar growth cacti and epiphytic cacti. The name is from the Latin cēreus, meaning "wax taper ", referring to the stiff, upright form of the columnar species. Some species of ceroid cacti were known as torch cactus or torch-thistle, supposedly due to their use as torches by Native Americans in the past.

<i>Hylocereus</i> Genus of cacti

Hylocereus is a former genus of epiphytic cacti, often referred to as night-blooming cactus. Several species previously placed in the genus have large edible fruits, which are known as pitayas, pitahayas or dragonfruits. In 2017, a molecular phylogenetic study confirmed an earlier finding that the genus Hylocereus was nested within Selenicereus, so all the species of Hylocereus were transferred to Selenicereus.

<i>Selenicereus</i> Genus of cacti

Selenicereus, sometimes known as moonlight cactus, is a genus of epiphytic, lithophytic, and terrestrial cacti, found in Mexico, Central America, the Caribbean and northern South America. The term night-blooming cereus is also sometimes used, but this is also used for many night-blooming cacti, including Epiphyllum and Peniocereus. In 2017, the genus Hylocereus was brought into synonymy with Selenicereus. A number of species of Selenicereus produce fruit that is eaten. The fruit, known as pitaya or pitahaya in Spanish or as dragon fruit, may be collected from the wild or the plants may be cultivated.

Disocactus crenatus, the crenate orchid cactus, is a species of cactus and a critical parent plant in creating the epiphyllum hybrids commonly cultivated worldwide. It is cultivated for its large flowers.

Epiphyllum oxypetalum, the Dutchman's pipe cactus, princess of the night or queen of the night, is a species of cactus with a native range from Mexico to Nicaragua.

Though it is sometimes referred to as a night-blooming cereus, it is not closely related to any of the species in the tribe Cereeae, such as Selenicereus, that are more commonly known as night-blooming cereus. All Cereus species bloom at night and are terrestrial plants; Epiphyllum species are usually epiphytic.
