Citrus bergamia: Citrus bergamia, the bergamot orange, is a fragrant citrus fruit the size of an orange, with a yellow or green colour similar to a lime, depending on ripeness. Genetic research into the ancestral origins of extant citrus cultivars found bergamot orange to be a probable hybrid of lemon and bitter orange. Citron: Citrus medica
Initially, many citrus types were identified and named by individual taxonomists, resulting in a large number of identified species: 870 by a 1969 count. [18] Some order was brought to citrus taxonomy by two unified classification schemes, those of Chōzaburō Tanaka and Walter Tennyson Swingle, that can be viewed as extreme alternative visions of the genus.
The generic name Citrus originates from Latin, where it denoted either the citron (C. medica) or a conifer tree . The Latin word is related to the ancient Greek word for the cedar of Lebanon, κέδρος (kédros), perhaps from a perceived similarity of the smell of citrus leaves and fruit with that of cedar. [24]

Citrus medica is a slow-growing shrub or small tree that reaches a height of about 8 to 15 ft (2 to 5 m). It has irregular straggling branches and stiff twigs and long spines at the leaf axils. The evergreen leaves are green and lemon-scented with slightly serrate edges, ovate-lanceolate or ovate elliptic 2.5 to 7.0 inches long.
Yuzu (Citrus × junos, from Japanese 柚子 or ユズ; / ˈ j uː z uː / ⓘ) is a citrus fruit and plant in the family Rutaceae of Chinese origin. [ 1 ] [ 2 ] Yuzu has been cultivated mainly in East Asia, though it has also recently been grown in New Zealand , Australia , Spain , Italy , and France .
The leaves are long, evergreen, glossy, and citron-like, being ovate elliptic in shape and lemon scented. [3] They have medium-thick branches with many spines. New growth is purple-tinged, as are the flowers. [4] Ponderosa lemon also has larger than average citrus flowers, and bears fruit throughout the year.
The leaves are also used in potpourri. [5] Lemon verbena is used to make herbal teas and as a liqueur flavoring. [9] It is used in traditional medicine in Latin American countries. [9] The oil was historically steam-distilled from the leaves for use in the perfume industry, but it has skin-sensitising and phototoxic properties. [10]
