John Baptist Banister was an English clergyman and one of the first university-trained naturalists in North America. His primary focus was botany but he also studied insects and molluscs. He was sent out as a missionary chaplain by the garden-loving Bishop Henry Compton, with whom he soon established a correspondence. Banister was first in Barbados in the West Indies and then by April 1679 in Virginia, where, while serving a rector of the parish of Charles City he became one of Bishop Compton's most energetic plant collectors, "the first Virginia botanist of any note".
