British botanist who spent the greater part of his career in Perak, Malaysia. Wray was appointed Superintendent of the Larut Hill Garden at Taiping, northern Perak, in 1881 and from 1883-1908 served as curator of the Perak State Museum. He was also Director of Museums in the Federated Malay States from 1905-1908. Wray gathered a considerable herbarium, which was organised in Calcutta. He also sent many plants to Kew and the British Museum, while those he kept are now held in Singapore. He collected with the zoologist Herbert Robinson in 1905.

As well as his extensive collecting activities, Wray developed a good knowledge of economic botany and ethnobotany in the Malay Peninsula, for example reporting on methods of gutta percha extraction and on poisons used by indigenous people. Many plants were named after him. Wray's father was known by the same name and also lived in the Malay Peninsula, therefore the younger Wray appended 'junior' to his name.
