Aerides lawrenciae is a species of orchid found only in the Philippines. It is classified as endangered by the 2007 IUCN Red List of Threatened Species.

Description

The plant is the largest in the genus Aerides, reaching a height of 4 to 6 feet with drooping racemes 18 to 20 inches long.[1] It has fragrant waxy white flowers with purple tips and green spur.[2]

Habitat and Distribution

This species is found in the wild only in the primary and secondary lowland forests of Mindanao (Cotabato and Davao) and Leyte.[2]

Cultivation and Uses

Aerides lawrenciae is found on branches of trees often overhanging bodies of water, and occasionally on rocks and stony landslides. It may be cultivated in hanging baskets and requires frequent watering.[1]

Relevance

This species was discovered by Roebelin in Mindanao in 1882. Roebelin was collecting orchids for Frederick Sander of St. Albans. The single Aerides lawrenciae plant brought back by Roebelin was sold on auction by Messrs. Stevens of King St., Covent Garden in London for 235 guineas to Sir Trevor Lawrence, then president of the British Royal Horticulture Society. The German taxonomist Heinrich Reichenbach named the orchid after Sir Trevor's wife.[3]

Due to loss and degradation of its limited habitat, and over-collecting of specimens, this species was declared by the IUCN Red List of Threatened Species to be Endangered.
