The leaves are oval, pointed at the front; the leaf stalk is one to 1.5 centimeters long, the whole leaf measures up to 30 centimeters in length and 13 centimeters in width and is therefore very large for a type of vanilla.

The flowers are yellowish, the lip is white with a red center. The sepals are oblong-oval and measure four centimeters in length, the petals are somewhat smaller, less fleshy and keeled on the outside. The 3.7 centimeter long lip is fused tubularly with the edges of the column at its base . Further in front the lip is indistinctly three-lobed, the side lobes are turned up, the edge of the lip is wavy. In the middle of the lip is a tuft of yellow hair that continues towards the base in a strip covered with papillae . The column is 2.5 inches long and hairy on the underside.
distribution
While Soto Arenas and Cribb describe Vanilla platyphylla as being endemic to Sulawesi, Rafael Govaerts also specifies an occurrence in the Philippines in WCSP. In 1909 she found it worse at Gunung Klabat .
Systematics and botanical history
After its discovery in 1909 Schlechter described this orchid in 1911. The name platyphylla is made up of the Greek words πλατύς platys , "broad", and φύλλον phyllon , "leaf".
Within the genus Vanilla , Vanilla platyphylla is classified in the subgenus Xanata and there in the section Thetya , which contains all species of the Paleotropic . According to Portères , Vanilla ovalis is particularly similar to Vanilla kempteriana, which occurs in New Guinea, and the species Vanilla albida and Vanilla wariensis . Soto Arenas and Cribb see great similarities to Vanilla kinabaluensis .
