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.
Flowers ca. 22 cm long, 21 cm wide, base with small, narrow, widely spaced scales, sometimes spiny. Fruit red. May be a synonym of Selenicereus triangularis: the Caribbean. [29] Selenicereus undatus (Haw.) D.R.Hunt: Stems green, margins undulate and horny. Flowers 25–30 cm long, white with green outer tepals and bracts. Fruit red with white pulp.
Dragon fruit sold in a market in Chiayi, Taiwan. A pitaya (/ p ɪ ˈ t aɪ. ə /) or pitahaya (/ ˌ p ɪ t ə ˈ h aɪ. ə /) is the fruit of several cactus species indigenous to the region of southern Mexico and along the Pacific coasts of Guatemala, Costa Rica, and El Salvador.
Bipolaris cactivora is an ascomycete, causing cactus stem rot and pitahaya (dragon fruit) rot. Also known as Drechslera cactivora, this fungus has been reported causing fruit rot on Hylocereus undatus (white-fleshed pitahaya). This specific cactus is both used decoratively as well as commercially in production of pitahaya fruit.
The species is grown commercially for its yellow fruit, but is also an impressive ornamental climbing vine with perhaps the largest flowers of all cacti. The yellow skinned fruit of S. megalanthus has thorns, unlike the green, red or yellow skinned dragon fruits of S. undatus, S. monacanthus and their cultivated hybrids.

Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma , either in the same flower or in another flower. Some tree species, including many fruit trees, do not produce fruit from self-pollination , so pollinizer trees are planted in orchards.
