Robert Allen Rolfe (1855, Wilford, Nottinghamshire[1] – 1921, Richmond, Surrey[2]) was an English botanist specialising in the study of orchids. For a time he worked in the gardens at Welbeck Abbey. He entered Kew in 1879 and became second assistant.
He was the first curator of the orchid herbarium at the Royal Botanic Gardens, Kew, founded the magazine The Orchid Review, and published many papers on hybrids of different species of orchids.
The genus Allenrolfea of amaranths was named after him by Carl Ernst Otto Kuntze.
Rolfe was buried in Richmond Cemetery.[3]
