Questions tagged [identification]

Use this tag for questions that ask "what is this thing?" Pictures, geographic location, and descriptive titles are important. Ask only one identification request per question. When you get an answer, consider adding a further tag (for the flower, tree, beetle etc. that has been identified) so your question is cataloged correctly. If the question is about determining the cause of a plant problem (e.g. disease), the diagnosis tag is more appropriate.
