The genus Ficus is also known commonly as Fig or Fig Trees, this large genus contains over 800 species of mostly evergreen trees and large shrubs, with some deciduous species and climbers. They grow to anywhere between 1–10m in height. Most produce aerial roots and characteristic smooth white bark. Although commonly referred to as a fruit, the fig is actually a fleshy, hollow-ended stem containing multiple flowers. More technically, this is classed as both a multiple and accessory fruit, rather than a true fruit. Figs are highly pollinator-specific, with most species pollinated by specific species of fig wasp. Some species are parthenocarpic, meaning they develop fruits without pollination. Leaf structure varies across species, the most well known of which belongs to F. carica, also known as the Common Fig, which has very distinctive leaves divided into 3 or 5 lobes. The sap can be a skin irritant and foliage can cause stomach upsets if ingested.
