(March 6, 1858 at Drumcro, County Antrim – June 8, 1919) was an Irish priest (Church of Ireland) and botanist.
He is known for work on difficult genera of flowering plants, such as brambles, roses, hawkweeds and knotweeds where asexual reproduction dominates leading to many microspecies.
[1] He was especially interested and specialised in bryophytes, especially liverworts and proposed the establishment of the Moss Exchange Club in 1896.
This members club for exchange of specimens and information later developed into the British Bryological Society.
He took a warm interest in the Belfast Naturalists' Field Club and served on the Committee.
