Remarks

The epithet honors Henry Nicholas Ridley (1855-1956), Director of the Singapore Botanic Gardens from 1888 to 1911. During his career he did much to found the Malayan rubber industry, but after retirement in 1911 Ridley went on to describe many new plants, among them the conifers Agathis flavescens and Podocarpus deflexus, and to write a flora of the Malay Peninsula (Ridley 1925).
