Gladiolus – A Revision Of The South African Species

Gladiolus: A Revision of the South African Species by G. Joyce Lewis et al., published by Purnell in 1972, remains a definitive botanical monograph on the rich diversity of South Africa’s native gladiolus species. Compiled by leading experts, this volume offers an exhaustive taxonomic treatment of the genus as it occurs in South Africa, making it an indispensable reference for botanists, horticulturists, conservationists, and plant-collectors interested in the region’s flora.

In Gladiolus: A Revision of the South African Species, readers will find comprehensive descriptions of each recognised species — detailing morphology, flowering characteristics, habitat, and distribution. The authors also provide identification keys and extensive botanical notes, enabling accurate differentiation between closely related species. The book is illustrated with detailed line drawings (and where available, photographs), offering visual support for the descriptions and aiding in field identification and scholarly study.

Published in 1972, this edition captures the state of botanical knowledge at the time and provides an important historical benchmark — helpful for understanding how taxonomic classifications, species ranges, and conservation concerns have evolved over time. For libraries, collectors, and specialists in South African botany or horticulture, Gladiolus: A Revision of the South African Species stands as a foundational volume. Its depth, clarity, and focus on a single important genus make it a valuable addition to any second-hand collection focused on southern African plant life.
