Here are examples of aspects of plant species that might be considered, not to say that all are immediately apparent or easily assessed. Systematic (taxonomic) aspects, e.g., traits for identification, name (scientific and common), classification, and phylogeny (evolutionary history and relationships) Geographic range, both natural and possibly expanded by human dispersal Habitat conditions where found Abundance, e.g., widespread and numerous, common but not abundant, relatively uncommon, truly rare Type(s) of ecosystem(s) where found and its ecological niche there, including functional aspects of the species Relationships to environmental conditions, e.g., o Light o Temperature o Moisture o Substrate physical and chemical conditions o
