William Wilson (botanist)

William M. Wilson (1799–1871) was an English botanist, known for his focus on bryology.

The second son of Thomas Wilson, a druggist, he was born at Warrington (which was then in Lancashire, and later transferred to Cheshire) on 7 June 1799. He was educated at Prestbury Grammar School and under Dr John Reynolds at the dissenting academy in Leaf Square, Manchester. He was then articled to a firm of solicitors in Manchester; but fell ill. This led to his love of botany, and when he was about 25, his mother gave him an allowance so that he could devote himself entirely to it.

In 1821 Wilson discovered Cotoneaster cambricus on Great Orme's Head. It brought him into correspondence with Sir James Edward Smith, who encouraged him. In 1827 John Stevens Henslow introduced him to William Jackson Hooker.

Wilson spent nearly two years in Ireland, where he studied mosses, which from 1830 took his whole attention. From 1829 onward he was frequently quoted in Hooker's British Flora. He became well known in his field.

Wilson died at Paddington, two miles from Warrington, on 3 April 1871, and was buried in the nonconformist burial-ground, Hill Cliff, Warrington. He had married in 1836 a widowed cousin, Eliza Lane.

Wilson was entrusted with the description of the mosses collected in the voyages of HMS Erebus and HMS Terror under James Clark Ross (expedition to Antarctica from 1839 to 1843), and of HMS Herald under Henry Kellett. He made an early account of Tasmanian mosses, describing many novelties.
