Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A spur in botany is a spike, usually part of a flower. In certain plants, part of a sepal or petal develops into an elongated hollow spike extending behind the flower, containing nectar which is sucked by long-tongued animals (insects, birds or bats). Plants with such structures include Delphinium, Aquilegia, Piperia, and some orchids, such as Gymnadenia. Spurs may be useful in species identification – for example Yadon's piperia cannot be easily distinguished from other Piperia save for the unusually short length of its spur.
