If you are interested in literature about tuberous Drosera you will always read one name: Allen Lowrie. He discovered many species of tuberous Drosera and other carnivorous plants in Australia and has published three books: Carnivorous Plants of Australia Magnum Opus Vol 1, Vol 2 and Vol 3. If someone is really interested in tuberous Drosera this three books are a must-have.
In addition to the Magnun opus that only carnivore plants are treated in Australia, there is another enormous work that is dedicated to the genus Drosera in general: "Drosera of the world" Volume 1, 2 and 3. These three volumes have been written by several authors, who ultimately represent a "who is who" of the Drosera world. Volumes 1 and 2 contain most of the information from the above Magnum Opus. These three books are also highly recommended, especially if you are not only interested in Australian carnivorous plants but also in the Drosera, which grow in the rest of the world. Since there are many people who cultivate the wintergrowing African Drosera species as well as the tuberous Drosera, because they have very similar growing conditions, these three books are probably even more recommendable than the three mentioned above.
In addition, there are some older books in which there are informations about tuberous Drosera, but which are not up to date due to the age, especially in the case of the research and the nomenclature. For instance in Allen Lowrie's last work, several new species were included and several subspecies were elevated to the rank of species and renamed.
One species was named after Allen Lowrie, Drosera lowriei.
