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 to orchid plants the transfer of these nutrients, as discussed, above is almost identical to that observed in arbuscular mycorrhiza and ericoid mycorrhiza, but when it comes to arguably the most fundamental element involved in mycorrhizal transport carbon, orchid mycorrhiza show a distinct divergence form the traditional paradigm of unidirectional nutrient transfer in mycorrhizal associations. Orchid mycorrhizal interactions encompass a large variety of symbiotic scenarios, ranging from fully mycoheterotrophic plants or in other words parasitic on their fungal inhabitant such as "Monotropa uniflora" which lacks chlorophyll, to interactions that take on a similar nature to those found in arbuscular mycorrhiza,
