The Peiffer Xylarium, known by the internationally accepted acronym of DOVw, is unique among wood collections because it also includes specimens that have their leaves, fruit, and scientific and common names lasered into the surface of the wood. The Peiffer Xylarium, established in 2006, now numbers about 6,000 specimens with the transfer of the Winterthur/Duke (WDw/DUKEw) collection in 2008. There are about one million xylarium specimens in worldwide collections:
The USDA Forest Products Laboratory of Madison, Wisconsin, has the world’s largest xylarium collection of about 98,000 specimens.
The Oxford Forestry Institute Xylarium in the UK has about13% of the world wood specimens mainly wood of former British colonies.
The Belgian Taxonomic facility contains 60,000 specimens specializing in African woods.
The University of Leningrad has the oldest collection, established in 1823.
Each added specimen is:
authenticated by the collector, and the county and state, or country in which the specimens were collected is noted.
3” wide x 12” tall x ¾" thick and the display surface is laser-carved with the:
FAMILY name, Genus and species name, and common name, leaves and fruit.
identified by a collection number which is stamped into both end surfaces.
Dr. Peiffer collected and milled the 75 newly added wood specimens as a hobby and to
supplement the Dendrology Course (Study of Trees) taught in the department from 1988-2005
by Adjunct Professor Charles J. Newlon, USDA Forest Service retired.
The project of adding original art work to each specimen began in August 2006.
The art work and layout are being created by Barbara J. Newlon.
A grant by Dr. Peiffer has helped to assure the preparation and art work for additional samples acquired in the next year or so.
The specimens of the entire Peiffer Xylarium are intended for display, scientific research, teaching, environmental education and other Herbarium programs. The goal is to continue collecting wood specimens, and whenever possible provide 3´´ wide x 12´´ tall x ¾´´ thick specimens to allow space for lasered art work, and to provide a vouchered herbarium specimen from the actual tree cut. Knowing the challenges of the latter goal, we welcome future donations especially in the 3´´ x 12´´ x ¾´´ size, with or without the backup herbarium specimen.
