Neomoorea wallisii is an orchid with a rare pumpkin orange color.
It was first described by Robert A. Rolfe in 1890 under the name of Moorea irrorata. Fourteen years later, he changed the name to Neomoorea because the original name was already assigned to a pampas grass. In 1991, botanists discovered that the description of Lueddemannia wallisii by Reichenbach in 1876 matched the earlier description by Rolfe and assigned the name Neomoorea wallisii.
Neomoorea wallisii is a large semi-epiphytic or terrestrial orchid with large, oval pseudobulbs which are deeply grooved and from which 2 big thick leaves grow. The leaves are pleated, up to more than 1 m high and 22 cm wide.
Each pseudobulb can produce an inflorescence of 60-70 cm high, with up to 20 flowers of 5-6 cm, fleshy, pumpkin colored flowers. The smell of the flowers is described as a mixture of plastic and lemon.
Vegetative growth occurs from spring to autumn, when the pseudobulbs produce new shoots. Growth then stops until the following spring.
