EARLY

Common Name The White Vanilla - In Thailand O lop, ka o lon, ngot khao

Flower Size 3" [7.5 cm]

Found in Andaman and Nicobar Islands, Sumatra, Java, the lesser Sunsa Islands and Borneo in tropical evergreen forests on rocks by waterfalls and in mixed deciduous forests at elevations around 70 to 600 meters as a giant sized, hot to warm growing, climbing terrestrial with an elongate, terete, leaf bearing stem carrying fleshy, lanceolate, acute, petiolate base leaves that blooms in the winter and early spring on rather angular, [1 to 3 cm] long, 6 to 12 flowered inflorescence with triangular, obtuse floral bracts carrying wide open flowers that close half way after a day or so.

"We interpret this species as the plant illustrated by Comber (1990) in Orchids of Java. It has flowers with green tepals and a large, deflexed, white lip with conspicuous trichomes at the lip apex. Vanilla albida is similar to V. montana and V. yersiniana, and they have been submerged in the synonymy of the former by some authors. However, V. montana has larger trichomes at the lip apex, broader leaves, and V. yersiniana has shorter trichomes and whiter tepals, longer sepals and shorter lip. The plant illustrated by Comber (1990) was collected on Gunong Hambali, Lenkong, SW Java, not far from Blume´s original locality. Comber (pers. comm.) indicated that the sepals become yellower with age. Blume´s plate 67 shows a flower also with greenish tepals, similar to Comber´s plant rather than to the Thailand plants identified as V. albida in recent years that must treated as V. yersiniana."
