Species Focus of 1st Quarter 2006 - Vandopsis gigantea

Vandopsis is a member of the large subfamily of Vandoideae under the tribe Vandeae that has been estimated to comprise of more than 1700 spesies in about 150 genera. It is divided into 3 subtribes, namely Aerangidinae, Angraecinae, and Aeridinae. Vandopsis gigantea belongs to the largest subtribe, Aeridinae, with some 1000 species widespread in mainland Asia, Australia, and the Pacific islands. The common name for Vandopsis gigantea is The Giant Vandopsis, named mostly due to its huge size that needs plenty of space for growth.

 

Vandopsis gigantea is a large, pendent, epiphytic plant that may grow into massive clumps. It does not have pseudobulbs. Its stems are about 1 in. thick. Its leaves can reach half a meter in length, but usually are about 14 in. long and 2.4 in. wide. The leaves are fleshy, leathery, and are extremely hard and stiff, a design suitable to take strong sunlight and withstand drought. The influorescence of Vandopsis gigantea is about 14 in. long, including the 4 in. raceme. Each raceme carries 6-18 flowers that are about 3 in. in diameter and can often last for several months in perfection. The broad, fleshy sepals and petals are pale yellow in colour with red-brown blotches that appear as rings with lighter coloured centres. The flowers are thick, heavy-textured, and vaguely fragrant at times.
