Gymnosperm Database: Links
These are links that provide significant additional information on many of the species addressed in the Gymnosperm Database. Because they are so comprehensive, it is not practical for me to add them to each page of each species concerned.
Conifers of the World This site provides an online portal to the complete BRAHMS database used by Aljos Farjon in his assembly of the "World Checklist and Bibliography of Conifers" and the "Handbook of the World's Conifers." Contains over 30,000 database records.
Africa Cycads -- Provides good photos, distribution maps and descriptions for all African cycads, i.e. Encephalartos and Stangeria.
Australia Virtual Herbarium (AVH) -- Excellent database containing records from most Australian herbaria.
Bibliography of Dendrochronology: Search Page -- Searchable database that includes virtually everything ever published on the subject of dendrochronology.
CalFlora -- A comprehensive database on the flora of California. Photos of most California gymnosperms.
Climate-Vegetation Atlas of North America: Conifers -- Online version of USGS Professional Paper 1650-A, with PDF files showing range and climatic requirements of most species of North American conifers. Very useful graphic presentation of climate requirements. See also THIS LINK, which has both distribution maps and downloadable ArcView shapefiles.
The Cycad Pages -- Provides information on all described cycad species, and extensive supplemental information.
Dendrobox -- Map-based engine to find and display tree-ring data archived by the International Tree-Ring Data Bank. Searchable by species, location, and investigator. This is one of the tools I use to find very old trees.
FEIS database -- FEIS was developed at the USDA Forest Service Intermountain Research Station's Fire Sciences Laboratory (IFSL) in Missoula, Montana. Among other things, it includes a database featuring many plant species found in the western United States, providing information on distribution, fire effects, value, ecological characteristics, and references for each species treated. I believe it includes all conifers of the western U.S.
Global Biodiversity Information Facility (GBIF) -- Currently the best database available on species distribution. Results can be downloaded as detailed KML files for display on Google Earth, containing links to herbarium data records. Extremely useful.
Inside Wood -- Essential resource for identifying a species by its wood. Includes both fossil and extant taxa (not just gymnosperms) with detailed information on anatomy and a large library of high-resolution photographs of woods in section.
New Zealand Virtual Herbarium -- Excellent database containing records from most New Zealand herbaria.
PLANTS Database -- The PLANTS Database is a single source of standardized information about plants. This database focuses on vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. The PLANTS Database includes names, checklists, automated tools, identification information, species abstracts, distributional data, crop information, plant symbols, plant growth data, plant materials information, plant links, references, and other plant information.
University of Michigan Native American Ethnobotany Database -- A database of foods, drugs, dyes and fibers of native american peoples, derived from plants.
Virtual Cycad Encyclopedia -- Administered by the Palm & Cycad Societies of Florida (PACSOF).
Herbarium RBGE -- Search the catalogue of the Royal Botanical Garden Edinburgh.

Herbarium NCU -- Search the catalog of the Flora of the Southeast, hosted by the University of North Carolina herbarium. Limited geographic range but very useful within its area.
Herbarium NYBG -- Search the catalog of the New York Botanical Garden. Limited usefulness because no location information for most species of interest.
USDA Integrated Taxonomic Information System -- Taxonomic information (authors, synonyms, common names, etc.) for most species native to or ornamental within North America. Generally very useful and recommended.
Conifer Treasury -- Comprehensive listing of conifer cultivar names and many incidentals of conifer culture assembled by Zsolt Mesterházy.
Digital Library de Real Jardín Bot&aacut;nico -- Extraordinary digital library containing color scans of the pages of some of the oldest works in botanical literature. Includes such gems as Linnaeus' 1754 Species Plantarum and Lambert's beautifully illustrated 1803 work on the Pinaceae.
PlantIllustrations.org -- Database of plant illustrations. Contains many great images scanned from old conifer books.
USDA Germplasm Resources Information Network (GRIN) -- Another excellent source of taxonomic information (authors, synonyms, common names, etc.) for most plant species of the world. Particularly handy for the obscure species.
NCBI Taxonomy Homepage -- Similar to the above pages, but with links to information on genetic research (it's a National Institutes of Health page). Fewer species than the USDA sites, and a less effective search engine, but with a more international selection of species.
Reforestation, Nurseries and Genetic Resources -- A fabulously rich site, especially for quality publications. Topics covered include seeds, nursery techniques, diagnosis and treatment of pests and diseases, reforestation, and much else.
