D.M. van Gelderen and his son C.J. van Gelderen have produced both a beautiful and most useful book in "Maples for Gardens - A Color Encyclopedia". The high-quality photographs (many unique to the book) make the publication ideal for the coffee table, while the arrangement and text ensure its functionality as a valuable reference.
One third of the book is dedicated to Japanese Maples, but the book covers in detail more than 80 other species of maple. This book has opened my eyes to the wonderful and diverse range of trees and shrubs in the maple family.
Here is an example of their informative and interesting descriptions (p.78):
"Acer laurinum. Section Hyptiocarpa. Synonum, A. javanicum. A small shrubby tree in cultivation, in its habitat a tree up to 30m (100 feet). Leaves 9-15 cm (3 1/2-6 inches) long and 5-8 cm (2-3 1/8 inches) wide, unlobed, evergreen and dark green. Flowers yellow, plants dioecious. Fruits erect, samaras 3-7 cm (1 1/8-2 3/4 inches) long. Native to mountainous regions, 1000-1500 m (3300-4900 feet), in Indonesia, Malaysia, Myanmar (Upper Burma), Hainan Province in China, and the Philippines. Originally described (as A. javanicum) by Franz Wilhelm Junghuhn in 1842. A plant cultivated in the Netherlands for several years was killed in the winter of 1991. Another specimen from a tropical greenhouse was transplanted but did not survice the operation. The species is probably extinct in cultivation. Zone 8 (Europe 9)."
Each entry has at least one photograph, and many have several. All photographs are in color.
The love the authors have for maples clearly shows in this fantastic book.
