旧大陆的猪笼草
As a supplementary volume to "Pitcher Plants of the Old World", the book covers taxa documented since the publication of that work in 2009, including 18 new species, 2 revised species, 1 new variety, and 2 new incompletely diagnosed taxa. The book provides detailed accounts of all of these taxa, often in the format of its predecessor, and these are accompanied by expedition reports and formal species descriptions. The content is arranged in broad geographical categories.
