. The new name of Vappodes phalaenopsis has now been accepted by the World Checklist of Monocotyledons, as a synonym of Dendrobium bigibbum Lindl., Paxton's Fl. Gard. 3: 25 (1852).

Description

This beautiful but variable orchid is closely related to several other species now listed in Vappodes and readily forms hybrids, which are now described under the "named hybrid genus" XVappaculum.

The colour of the flowers varies from pinkish-mauve to lavender or purple and sometimes almost white, with the base of the labellum

The plants can grow up to 80 cm in height. The flowers are on canes 10–40 cm long. Flowering time is usually in the dry season between March and July; but sometimes all year in commercial cultivation. The flowers are on racemes 200–400 mm long and are usually lilac-purple, but can be bluish or even white and sometimes pinkish with darker purple labellum without a white spot.

Habitat

It lives in a wide variety of habitats ranging from coastal scrub on trees and rocks, to mangroves, riverine vegetation, rainforest, vine thickets, gullies in open forest and even swamps. It used to be prolific around Cooktown

Cultivation and uses

Likes a dry, sunny position with a minimum of watering and a temperature not below 13°C. Needs a bush-house in cooler climates. Cultivated plants often have much larger flowers than those in the wild.

Queensland State Floral Emblem

Queensland, in preparation for its 1959 Centenary, sought advice what native species would be a good floral emblem. Specifically, the government was looking for an easily grown species found only in Queensland, which was decorative, distinctive, and close to the State colour, maroon. The Cooktown Orchid, which meets these criteria, was one of the four initial suggestions, the others being the Red Silky Oak (Grevillea banksii
