In April 1907 part of Margaret Gatty’s herbarium was donated by her daughter to the Gatty Marine Laboratory in St Andrews and later incorporated into the St Andrews University Herbarium in the Department of Botany. Starting in 1947 these specimens were partly described by Helen Blackler. More recently the herbarium was moved to the St Andrews Botanic Garden. The laboratory was named after its benefactor Charles Henry Gatty (1836-1903), a distant cousin of Gatty’s husband. A total of 8,825 specimens and 500 plates exist currently at St Andrews, many in their original albums.
