A treatise on the conduplicate-leafed slipper orchids of Latin America by Guido J. Braem. Published in 2018, this book is probably the best treatise on Phragmipedium species. It is a beautiful book with wonderful photos and illustrations and excellent taxonomy. Many of the photos are in situ. There is also a section on Phragmipedium culture by Eric Sauer that is important to have in a book on Phragmipediums. Book size is 6.5" x 9.5" with 305 pages. Very limited first edition printing of just 400 copies. An excellent book to add to your orchid reference library and should become more valuable over time.
