description

Vanilla cucullata is an evergreen climber with a relatively thick shoot. The leaves are elongated, asymmetrically heart-shaped at the base with a short petiole (one centimeter long), ending with a pointed tip. They are ten to 15 inches long and three to six inches wide.

The inflorescence axis is up to four centimeters long, mostly unbranched, bent in a zigzag shape. The bracts are triangular and reduced like scales. The flower stalk and ovary together become 2.5 inches long. The flowers are 2.5 inches long and 1.5 to two inches in diameter. Sepals and petals are oval, about two inches long. The lip is unlobed or slightly three-lobed, roughly triangular in outline, pointed at the front. Three keels run along the lip, which are provided with teeth pointing backwards. The curved column is 1.7 centimeters long, it is fused to the lip up to a third. At the front end, the column is widened laterally (winged).

distribution

Vanilla cucullata occurs in western Africa in the countries of Ivory Coast , Cameroon and Gabon . Portères indicates a disjoint area at Dar-es-Salam in East Africa.

Systematics and botanical history

Vanilla cucullata was first described by Kraenzlin in 1889 .

According to Portères, Vanilla cucullata is similar to other African vanilla species such as Vanilla acuminata , Vanilla africana and Vanilla ramosa . Soto Arenas and Cribb write that it may be indistinguishable from Vanilla crenulata . In addition to the species mentioned by Portères, they give Vanilla hallei , Vanilla heterolopha and Vanilla zanzibarica as relatives.
