|
- biotic pressure

Notes:
- This is version: 2.1 Last updated: February 4, 2002.
- If you are looking up names of plants, check the HortiPlex plant database here at GardenWeb.
- Proper nouns are generally not included in the glossary.
- Searches are case insensitive.
- You can browse the glossary, but there are many pages.
- Multiple keywords can be searched so that each word must appear in each hit (boolean "and") or so that only one of the words must appear (boolean "or").
- To increase the chances of matching keywords with multiple endings, search for "Word Roots." With this setting, epiphyt will match both epiphyte and epiphytic.
- You can also limit your search to just terms or just definition.
- Additional Passes: If there are no hits in the first search, common word endings (-ing, -es, -ed, -ly) are stripped from the keywords and a second pass is made. If there is still no match, all non-word characters are stripped.
- This glossary was compiled by the editors of GardenWeb from a variety of sources. It is updated continually.
- If you encounter any problems, or feel that there are terms that should be in the database and are not, please let us know.
