Charles Maries (18 December 1851 – 11 October 1902) was an English botanist and plant collector who was sent by James Veitch & Sons of Chelsea, London to search for new hardy plants in Japan, China and Taiwan between 1877 and 1879; there he discovered over 500 new species, which Veitch introduced to England. Amongst his finds, several bear his name, including Abies mariesii, Davallia mariesii, Hydrangea macrophylla "Mariesii", Platycodon grandiflorus "Mariesii" and Viburnum plicatum "Mariesii".
Maries was born in Hampton Lucy, Warwickshire, the youngest of five sons born to George and Mary Maries. His father was the boot- and shoe-maker for the village, as was his grandfather, Thomas Maries. He was educated at the Hampton Lucy Grammar School, where he learnt about plants from the Reverend George Henslow, who was headmaster between 1861 and 1865. Reverend Henslow went on to become the Royal Horticultural Society's Professor of Botany.
Of his brothers, Frederick (the eldest brother) and George followed their father and became cordwainers and shoe-makers, while Henry became a music teacher at Stratford-upon-Avon. The fourth brother, Richard, also had a strong interest in plants and he set up as a florist and nurseryman in Lytham, Lancashire. When their father died in 1869, Charles moved to Lytham to work at Richard's nursery.
After seven years working with Richard, Charles joined James Veitch & Sons of Chelsea, London in 1876, then one of the largest nurseries in Britain. According to "Hortus Veitchii", "he proved to be an industrious and steady workman" and he was soon promoted to foreman. His knowledge of Japanese and Chinese plants led to him being invited by Harry Veitch to "undertake an exploring expedition to the Far East, the object of which was to obtain seeds of the coniferous trees of Japan, and to explore the great Yangtze valley of China".
