Primula (edição 1993)

"This revision brings this definitive reference work up to date and incorporates new and improved information for most of the species. For the first time, identification keys are included for all species, and other special features include several newly described species, over 30 new illustrations, and important fresh details on the evolutionary history of Primulas from recent DNA evidence, leading to major changes in classification. The book covers the historical and practical information on the exploration and cultivation of the genus; the evolution of the species; and a chapter on heterostyly and homostyly includes the latest developments in this subject. However, the bulk of the book is given over to a systematic treatment of each species." "Illustrated with over 100 drawings and photographs, including the coloured paintings by the award-winning botanical illustrator Brigid Edwards."--BOOK JACKET.
