Vanilla ([ ʋanɪljə ] or [ vanɪlə ], landscape based also [ fanɪlə ] or [ vanɪl ]; botanical Vanilla ) is a genus in the family of orchid (Orchidaceae). The 106 to 127 species are common in the subtropics to the tropics .

Vegetative characteristics

The vegetative characteristics of many species vary greatly and are therefore poorly suited as identifying characteristics. The species of the genus Vanilla are evergreen, perennial herbaceous plants . These climbing plants grow directly in the ground rooting ( terrestrial ) or semi-epiphytic . The thick, bare, green, monopodial stem axis sometimes branches and is succulent . The gray-green roots arise at each node of the stem axis. Their leaves are leathery, thick and fleshy; they can be large and elongated or scale-shaped.

Generative characteristics

The racemose inflorescence is short and densely covered with resupinate flowers. The relatively short-lived flowers are striking. The hermaphrodite flowers are zygomorphic and threefold. The sepals are free.

Botanically speaking, the fruits are elongated capsule fruits or cylindrical, leathery berries that do not open. The fruits are also called "vanilla pods" when fermented and used as a spice. As with all orchids, the fruits contain a large number of very small seeds. The seed coat (testa) is hard.

Systematics, botanical history and distribution

Botanical history and taxonomy

The first species belonging to the genus Vanilla was named before the binomial system of nomenclature after Carl von Linné was established in 1753. The genus Vanilla was on 28 January 1754 by Philip Miller in The Gardeners Dictionary ... Abridged ... fourth edition installed . As Lectotypusart was Vanilla mexicana Mill. (Syn .: Epidendrum vanilla L. ) by Mansfield in crop set 2, 1959, Page 587. Synonyms for Vanilla Plum. ex Mill. are: Myrobroma Salisb. , Vanillophorum Neck. nom. inval.

Important revisions of the genus Vanilla were carried out by Klotzsch in 1846, Rolfe in 1896 and Portères in 1954. After molecular genetic data, a comprehensive revision was carried out by Arenas et al. 2010.

External system

The genus Vanilla belongs to the tribe Vanilleae in the subfamily Vanilloideae within the family Orchidaceae . According to Arenas 2010, the genus is Vanilla Plum. ex Mill. closest related to the genera Dictyophyllaria Garay , Epistephium Kunth and Lecanorchis Blum . According to Pansarin 2010, the only species in the genus Dictyophyllaria Garay belongs to the genus Vanilla again .

Internal system

The genus Vanilla was identified by Arenas et al. 2010 divided into two sub-categories:

  • Subgenus Vanilla Mill. Subg. Vanilla (Syn .: Vanilla subsect. Membranacea Portères nom. Illeg.): It contains about 15 Neotropical species, most of which are found in Brazil.
  • Subgenus Vanilla subg. Xanata Soto Arenas & Cribb : It was set up in 2010 and is divided into two sections:
    • Vanilla subg. Xanata sect. Tethya Soto Arenas & Cribb : It was set up in 2010.
    • Vanilla subg. Xanata Soto Arenas & Cribb sect. Xanata
The distribution of the genus Vanilla in the world

Species and their distribution

The distribution area of the genus Vanilla are the tropical and subtropical areas of different continents. There are areas in the southern area of North America , on the Caribbean Islands , in Central America , South America , Central Africa , Madagascar , Southeast Asia and on the western Pacific islands .

The original distribution of most species is South America, although a few species, such as Vanilla imperialis or Vanilla roscheri, are native to the African continent.

The genus Vanilla contains 106 to 127 species, depending on the author:

  • Vanilla × tahitensis ( Tahitian vanilla ) = Vanilla odorata × Vanilla planifolia

use

The best known and economically most important representative is the spiced vanilla or real vanilla ( Vanilla planifolia ). The seasoning vanilla is obtained from the fermented capsules ("vanilla pods") of this plant . Around 15 species bear aromatic fruits. Some other types of vanilla, such as Tahitian vanilla ( Vanilla tahitensis and Vanilla pompona ) are used commercially. These types of vanilla can also be used in the kitchen. However, since the ingredients are composed a little differently from real vanilla, the aroma is not quite as fruity. However, the Tahitian vanilla is mainly used for use in cosmetics.
