Hore was essentially a Devonshire botanist, but during the course of his life he moved around and was ‘well connected’. He was born in Stonehouse, Plymouth in 1807 and some years later was an undergraduate at Cambridge. It was here that his taste for natural history developed, and he benefited from the friendship and acquaintance of people such as Professor Henslow, Darwin and Babington.
After Cambridge, he held curacies at a number of places – Combe Martin, Stoke Damerel and Norwich. In 1850, he was preferred to the vicarage of St Clement’s, Oxford and then to the living at Shebbear with Sheepwash (Devon).
He contributed a ‘List of plants found in Devonshire and Cornwall not mentioned by Jones in the Flora Devoniensis‘ to the British Association meeting in Plymouth in 1841; this later appeared in The Phytologist.
In the same publication (Vol 2) is his paper on Orobranche amethystea (Whitsand Bay, Cornwall). He later discovered (1843) Listera cordata in North devon. A genus of algae Horea was named after him by Professor Harvey, who commented that he was an ‘excellent algologist‘ and ‘an ardent and successful explorer of Plymouth sound‘.
In his later years, he lived at Penrose Villas, Barnstable with his sisters (Amelia and Rachel), who acted as his executrices on his death in February 1882.
