Gilbert Westacott Reynolds (1895–1967) was the doyen of Aloe students from 1930 to 1966. The first bibliography of his work is provided. It lists a total of 122 publications on the genus, of which 8 are books, the major ones being The Aloes of South Africa (1950, with three later editions) and The Aloes of Tropical Africa and Madagascar (1966). He published 73 papers in the Journal of South African Botany in which species were revised and new ones described. He named 83 new species and 19 new varieties: these 102 names account for c.11% of new epithets published in Aloe since 1753, making him the most prolific publisher of such names of all time. It is emphasized that Reynolds aimed to illustrate his publications with high quality photos and a previously unpublished proof plate is included as an example of his work. He published a series of travelogues from which brief extracts with commentaries are included. Notes are also provided on some of his major collaborators for his studies in tropical Africa and on his commemorations and awards.
