Taxonomy

Ficus crassiuscula was first described in 1917. [2] In the 1960 Flora of Panama Gordon P. DeWolf Jr. considered this species to be a synonym of the non-climbing F. insipida, [4] but this taxonomic interpretation has not been followed by subsequent authorities. [3]

With about 750 species, Ficus (Moraceae) is one of the largest angiosperm genera. [5] F. insipida is classified in subgenus Pharmacosycea , section Pharmacosycea, subsection Bergianae, along with F. adhatodifolia, F. carchiana, F. gigantosyce, F. insipida, F. lapathifolia, F. mutisii, F. oapana (spec. nov.? ined.), F. obtusiuscula, F. piresiana, F. rieberiana and F. yoponensis. [6] Although recent work suggests that subgenus Pharmacosycea is polyphyletic, section Pharmacosycea appears to be monophyletic and is a sister group to the rest of the genus Ficus. [7]

Description

Among the fig species in subgenus Pharmacosycea, Ficus crassiuscula is quite unique: all the other species are tall, non-climbing, free-growing trees, but F. crassiuscula instead starts its life as an epiphyte (it is a hemiepiphyte), usually germinating near the ground on the lower tree trunk. It spreads from here as a vine, which roots freely at its nodes in order to climb. As a juvenile it also spreads along the ground, sometimes eventually forming a sprawling thicket - this enables the plant to find its favourite host trees. Eventually parts of it change from a vine to sapling with erect stems, which may eventually become the mature tree, this transformation usually occur when the vine has reached the crotch of a branch or the top of a tree stump. [6] [8]

It has dimorphic leaves: the leaves of this species change in shape as it progresses from a juvenile to a mature plant. [6] [8]

When mature, it is 20 to 35 meters tall. The leaves are ovoid and shiny, reaching 7cm wide and 16cm long. It flowers February to April and bears warty, yellow-green fruit that are 4 to 6 cm in diameter. [9]

Ecology

It is found in lower montane rainforests. [8] In Costa Rica, F. crassiuscula is found in cloud forest above 1550 meters in altitude. [9] Although it is a free-standing tree when mature, F. crassiuscula begins its growth as a climbing vine. It clings to a mature tree, eventually strangling it. Its favoured hosts are Guarea tuisana and Sapium pachystachys , and it is also frequently found on already-dead trees. [8]

Monkeys feed on fruits while they are still on the tree, and the fallen fruits are eaten by peccaries. [9]

Uses

The wood is soft, but it is used for construction purposes where durability is not important. [9]

<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.

<span class="mw-page-title-main">Banyan</span> Subgenus of plants, the banyans

A banyan, also spelled "banian", is a fig that develops accessory trunks from adventitious prop roots, allowing the tree to spread outwards indefinitely. This distinguishes banyans from other trees with a strangler habit that begin life as an epiphyte, i.e. a plant that grows on another plant, when its seed germinates in a crack or crevice of a host tree or edifice. "Banyan" often specifically denotes Ficus benghalensis, which is the national tree of India, though the name has also been generalized to denominate all figs that share a common life cycle and used systematically in taxonomy to denominate the subgenus Urostigma.

<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. Its common name is derived from Moreton Bay in Queensland, Australia. It is best known for its imposing buttress roots.

<i>Ficus rubiginosa</i> Species of flowering plant in the family Moraceaea native to eastern Australia

Ficus rubiginosa, the rusty fig or Port Jackson fig, is a species of flowering plant native to eastern Australia in the genus Ficus. Beginning as a seedling that grows on other plants (hemiepiphyte) or rocks (lithophyte), F. rubiginosa matures into a tree 30 m (100 ft) high and nearly as wide with a yellow-brown buttressed trunk. The leaves are oval and glossy green and measure from 4 to 19.3 cm long and 1.25 to 13.2 cm wide.

Ficus aurea, commonly known as the Florida strangler fig, golden fig, or higuerón, is a tree in the family Moraceae that is native to the U.S. state of Florida, the northern and western Caribbean, southern Mexico and Central America south to Panama. The specific epithet aurea was applied by English botanist Thomas Nuttall who described the species in 1846.

Ficus maxima is a fig tree which is native to Mexico, Central America, the Caribbean and South America south to Paraguay. Figs belong to the family Moraceae. The specific epithet maxima was coined by Scottish botanist Philip Miller in 1768; Miller's name was applied to this species in the Flora of Jamaica, but it was later determined that Miller's description was actually of the species now known as Ficus aurea. To avoid confusion, Cornelis Berg proposed that the name should be conserved for this species. Berg's proposal was accepted in 2005.

<i>Ficus obliqua</i> A tree, the small-leaved fig

Ficus obliqua, commonly known as the small-leaved fig, is a tree in the family Moraceae, native to eastern Australia, New Guinea, eastern Indonesia to Sulawesi and islands in the southwestern Pacific Ocean. Previously known for many years as Ficus eugenioides, it is a banyan of the genus Ficus, which contains around 750 species worldwide in warm climates, including the edible fig. Beginning life as a seedling, which grows on other plants (epiphyte) or on rocks (lithophyte), F. obliqua can grow to 60 m (200 ft) high and nearly as wide with a pale grey buttressed trunk, and glossy green leaves.

Ficus yoponensis is a species of fig tree found in Central and South America. It can grow to heights of 40–50 metres (130–160 ft) tall, having a trunk diameter of 1 metre (3.3 ft). The trunk is buttressed, light grey in colour and reasonably smooth. Its petioles are 1–2.5 centimetres (0.39–0.98 in) long, the stipules are straight and 3–5 centimetres (1.2–2.0 in) long. The leaves and stems are hairless. The leaves are 6–11 centimetres (2.4–4.3 in) long and 2.5–4 centimetres (0.98–1.57 in) wide, but larger in juveniles, being up to 28 centimetres (11 in) long and 5 centimetres (2.0 in) wide. The time at which they flower varies between individuals, but each tree tends to flower at a similar time each year. As in all figs, the flowers are enclosed inside the fig and can only be accessed by fig wasps, which enter to pollinate the flowers and lay their own eggs. The resulting fruit grows to 1.8 centimetres (0.71 in) in diameter and turns from green to purple with maturity. On average in Panama, F. yoponensis produce a new flush of leaves every 20 weeks and flower every 25 weeks. The species is similar in appearance to Ficus insipida but has smaller leaves, stipules and fruits and only occurs in primary forest whereas F. insipida is also found in secondary forest.
