Vanilla planifolia Vanilla planifolia Vanilla planifolia is a species of vanilla orchid. It is native to Mexico and Central America, and is one of the primary sources for vanilla flavouring, due to its high vanillin content. Common names are flat-leaved vanilla, Tahitian vanilla, and West Indian vanilla (also used for the Pompona vanilla, "V. pompona"). Often, it is simply referred to as "the vanilla". It was first scientifically named in 1808. "Vanilla planifolia" is found in Mexico, Central America, the Caribbean, and northeastern South America. It prefers hot, wet, tropical climates. It is cultivated and harvested primarily in Veracruz, Mexico and in
Orchid mycorrhiza roots happens mainly through root hair tips, which then take on a distorted shape. Typically, the partnership is maintained throughout the lifetime of the orchid because they depend on the fungus for nutrients including minerals. However, some orchids have been found to switch fungal partners during extreme conditions. Shortly after the fungus enters an orchid, the fungus produces intracellular hyphal coils, called pelotons, in the embryos of developing seedlings and the roots of adult plants. The formation of pelotons in root cortical cells is a defining anatomical structure in orchid mycorrhiza that differentiate it from other forms of mycorrhiza. The
