Ficus auriculata (the Roxburgh fig, Elephant ear tree) is a type of fig tree, native to subtropical and tropical mainland Asia. [2] It is noted for its big and round leaves and edible fruit.

Contents

Description

This plant is a small tree of 5–10 m (16–33 ft) high with numerous bristle-covered branches. The leaves are big and round, and are up to 44 cm (17 in) long and 45 cm (18 in) wide, with cordate or rounded base, acute apex, and 5–7 main veins from the leaf base. Its petioles are up to 15 cm (6 in) long, and it has stipules of about 2.5 cm (1 in) long. The plant has oblate syconium that are up to 4 cm (1.6 in) wide, covered with yellow pubescence, and emerge from the trunk or old branches of the tree. [3] [4] Ficus auriculata is dioecious, with male and female flowers produced on separate individuals. [5] On ripening, the fruits turn from light yellow to purple. The fruit is a fleshy receptacle. The fruits form as large clusters on the trunk, on branches and also on the roots. [6]

Fruit extracts contain many phenolic compounds (Gaire et al. 2011). [7]

Taxonomy

It was first published by Portuguese Botanist João de Loureiro (1717–1791), in Fl. Cochinch. on page 666 in 1790. [2]

It is commonly known as the Roxburgh fig, [8] which is named after botanist William Roxburgh, who was appointed Superintendent of the Calcutta Botanical Gardens by the East India Company in 1793. Experiments carried out on fruiting Ficus auriculata trees at the Calcutta Botanic Gardens by the then Superintendent George King and his Botanic Garden colleagues described in King in 1897 which was the first detailed explanation of how the dioecious figs were pollinated by fig wasps which bred in the figs of male trees and then flew to female fig trees to pollinate the female figs. [9] It is also known as Elephant Ear Fig Tree, Elephant Ear Tree and Giant Indian Fig, due to the leaves, as auricle is the Latin word for ear, referring to the two 'ears' at the base of heart shaped leaf. [6]

Distribution

The native range of this species stretches from north-eastern Pakistan to southern China and the Malaysian peninsula. It is found in the countries (and regions) of Assam, Bangladesh, Cambodia, southern China, East and West Himalaya, Hainan, India, Laos, Malaya, Myanmar, Nepal, Pakistan, Thailand, Tibet and Vietnam. [2]

Habitat

It grows in forests in moist valleys, [3] growing along stream banks. [6]

Ecology

Ceratosolen emarginatus is an insect that helps to pollinate this plant. [10] [11]

Uses

The fresh fruit of this plant is consumed as food, and has diuretic, laxative and digestive regulating properties. [4] Ficus auriculata is used as fodder in Nepal. It is least resistant to fire, but likes good sunlight. [12]

The large leaves, often up to 21 in (533.4 mm) long and 12 in (304.8 mm) wide are used as plates. [6]

Plant problems

The tree is susceptible to scale. It also has minor issues with gall, mealy bugs, thrips, whitefly, and spider mite. [6]

<i>Ficus</i> Genus of flowering plants in the mulberry family Moraceae

Ficus is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (F. carica) is a temperate species native to southwest Asia and the Mediterranean region, which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses.

<i>Ficus macrophylla</i> Species of banyan tree

Ficus macrophylla, commonly known as the Moreton Bay fig or Australian banyan, is a large evergreen banyan tree of the Mulberry Family (Moraceae) native to eastern Australia, from the Wide Bay–Burnett region in the north to the Illawarra in New South Wales, as well as Lord Howe Island where the subspecies F. m. columnaris is a banyan form covering 2.5 acres or more of ground.
