Flag trees are prominent on the landscape. Many flag trees stand tall on hilltops, or are visible from a long distance. They can be found in the center of a plaza, or along the edge of a cliff. They can be of any species, but are often tall, upright trees, and are natural landmarks for travellers and locals.
Flag trees often appear in photographs, and are sometimes instantly recognizable. For example, the Flag of Gwalior, appears in many pictures of the Elephant Gate entrance to Gwalior Fort.
A flag is usually a piece of fabric with a distinctive design that is usually rectangular and used as a symbol, as a signaling device, or decoration. The term flag is also used to refer to the graphic design employed by a flag, or to its depiction in another medium.
The first flags were used to assist military coordination on battlefields, and flags have since evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is similarly challenging (such as the maritime environment where semaphore is used). National flags are potent patriotic symbols with varied wide-ranging interpretations, often including strong military associations due to their original and ongoing military uses. Flags are also used in messaging, advertising, or for other decorative purposes. The study of flags is known as vexillology, from the Latin vexillum meaning flag or banner.
