This collection includes are five letters (1970–1972) to Kasapligil from botanical author and illustrator John Hutchinson (1884–1972), who began his career on the herbarium staff at the Royal Botanic Gardens, Kew (1905) and became keeper of the Museum of Botany there (1936–1948). The letters refer to Hutchinson’s activities; to his wife and his daughter Joan; the success with which his Evolution and Phylogeny of Flowering Plants (London, New York, Academic Press, 1969; HI call no.

DS1 H975F 959), was selling; his work on a supplement to the two volumes of his Genera of Flowering Plants (Oxford, Clarendon Press, 1964–1967; HI call no.

DS1 H975K 967); John Heslop-Harrison’s (1920–1998) appointment as director of Kew (with Hutchinson’s hopes that he will prove better than certain of his predecessors); and Hutchinson’s years spent at the Kew Herbarium.
