    At the Institute of Forest Genetics, Placerville, California), we have recently organized a specialized herbarium of pines (Pinus) and firs {Abies). Incorporated in it are the many specimens that have accumulated since the Institute was established in 1925. Like the Eddy Arboretum, the herbarium is an integral part of our research program, which is concerned with the genetic improvement of conifers native to the western United States. Interspecific hybridization and geographic variability are important parts of the program, and the herbarium is particulary useful in documenting this research.
