Can you explain the scientific classifications of dragon fruit

Origin and distribution

The dragon fruit’s scientific name is derived from the Greek word hyle (woody), the Latin word cereus (waxen) and the Latin word undatus, which refers to the wavy edges of its stems.

The origin of the dragon fruit is unknown, but it is probably native to Central America.

Dragon Fruit is also known as pitahaya in Mexico, and pitaya roja in Central America and northern South America.

The Spanish name pitahaya may also refer to several other species of tall cacti with flowering fruit.

  1. Family: Orders are divided into families, which consist of closely related plants that share more specific features. The family for dragon fruit is Cactaceae

  2. Genus: Families are further subdivided into genera (plural of genus), which group together species that are very closely related and share a common ancestor. The genus name is capitalized and italicized (or underlined). Selenicereus or Hylocereus

  3. Species: The species is the most specific level of classification and represents a group of plants that are very similar and can interbreed to produce fertile offspring. The species name is written in lowercase and italicized (or underlined) 

  4. Common Name: Pitaya, Dragon fruit and strawberry pear.

For example: Maria Rosa Dragon Fruit is a hybrid variety that comes from Hylocereus undatus and Hylocereus guatemalensis.

You will find this written as H. undatus X H. guatemalensis.

The have also been  breed for commercial qualities size, skin thickness and shelf life. 

It's important to note that the scientific classification of dragon fruit species may evolve as botanists conduct more research and make new discoveries.

Dragon fruit is a popular fruit in many parts of the world due to its unique appearance and mild, sweet taste, and it has gained popularity for its potential health benefits.
