If you are looking up names of plants, check the Horti Plex 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. With this setting, epiphyt will match both epiphyte and epiphytic. You can also limit your search to just terms or just definition. 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.
