Vanilla insignis is a species of plant in the genus Vanilla ( Vanilla ) in the orchid family (Orchidaceae). The climbing plant is found in Central America.
description
Vanilla insignis is an epiphytic , evergreen climbing plant. The length of the internodes is 10 to 14 centimeters. The stem is furrowed lengthways and covered with tiny papillae . The short-stalked leaves are elongated to oval in shape, with an attached tip at the front. The leaf length is 11.5 to 15 centimeters, the width 4 centimeters.
The inflorescence axis becomes 3 to 4 centimeters long. The bracts are up to 0.7 inches long, broadly oval in shape, they end pointed, they are fleshy and concave. The ovary is 3.5 to 4.5 inches long. The flowers are greenish with a white lip . The sepals are elongated to lanceolate, widest above the center, 6.9 to 7.5 inches long and 1.1 to 1.4 inches wide. The lateral petals are somewhat narrower, keeled on the outside. The lip becomes 6.5 to 7 centimeters long, it is indistinctly three-lobed. At the base, the lip is fused with the column to form a tube. The front free part of the lip is spread out and fringed on the edge. The hairiness of the lip begins at the base with thick, glandular hairs; in the middle of the lip there is a tuft of hair directed backwards; before that, only the veins are slightly warty, further towards the tip the appendages become longer (up to 0.5 centimeters) and denser. The slightly S-shaped curved column is 5 centimeters long, it is hairy on the underside, yellow at the top, otherwise white.
distribution
Vanilla insignis is only known from Central America, it grows in Mexico, Belize, Guatemala and Honduras, possibly also in Costa Rica. It is quite common, but flowering plants were rarely collected.
Systematics and botanical history
This orchid was described by Oakes Ames in 1934 . JB Edwards found them in 1933 in Comayagua department at an altitude of about 800 meters, where the plants grew in sparse forests.
Within the genus Vanilla , Vanilla insignis is classified in the subgenus Xanata and there in the section Xanata , which only contains species of the Neotropics . Soto Arenas and Cribb place them in a group around Vanilla odorata and Vanilla planifolia , which include the other species Vanilla appendiculata , Vanilla bahiana , Vanilla cristagalli , Vanilla denticulata , Vanilla dubia , Vanilla dungsii , Vanilla fimbriata , Vanilla helleri , Vanilla phaeantha , Vanilla Contains ribeiroi , Vanilla schwackeana , Vanilla tahitiensis and Vanilla uncinata .
