Lacmellea panamensis

Lacmellea panamensis is a species of tree in the family Apocynaceae native to Costa Rica, Panama, Nicaragua, Colombia, and Ecuador. [1] It is a medium-sized tree, with a straight trunk, that is scattered with conical spines that are rather blunt, a distinctive feature of the species. Its leaves are around 10 centimetres (3.9 in) long, spaced evenly along branches, simple in shape, dark green and if damaged produce a white latex. Their flowers are white and around 3 centimetres (1.2 in) long thin tubes and develop into yellow berries of 3 cm in diameter. [2] [3]

Its seeds weigh around 0.25 grams (0.0088 oz) and when they germinate the cotyledons remains underground, acting as an energy store. In an artificial experiment, 80% of seedlings were able to survive having their leaves removed, or being placed in deep shade (0.08% of full sunlight), making them relatively shade tolerant. [4]

<i>Enterolobium cyclocarpum</i> Species of legume

Enterolobium cyclocarpum, commonly known as conacaste, guanacaste, caro caro, devil's ear tree, monkey-ear tree, or elephant-ear tree, is a species of flowering tree in the family Fabaceae, that is native to tropical regions of the Americas, from central Mexico south to northern Brazil (Roraima) and Venezuela. It is known for its large proportions, expansive, often spherical crown, and curiously shaped seedpods. The abundance of this tree, especially in Guanacaste Province, Costa Rica, where it is prized for the shady relief it provides from the intense sun, coupled with its immensity, have made it a widely recognized species. It is the national tree of Costa Rica.

<i>Lansium parasiticum</i> Species of tree

Lansium parasiticum, commonly known as langsat, lanzones, or longkong in English; duku in Indonesian or dokong in Terengganu Malay, is a species of tree in the Mahogany family with commercially cultivated edible fruits. The species is native to Southeast Asia. Despite its name, it is not parasitic; the specific epithet parasiticum derives from the fact that it can grow as an epiphyte in the wild, which was once thought to be an indication of parasitism.

Inga feuilleei, commonly known as pacay or ice-cream bean tree, is a tree in the family Fabaceae native to Andean valleys of northwestern South America. Pacay trees, as is the case with other trees in genus Inga, produce pods that contain an edible white pulp and have nitrogen-fixing roots.

<i>Simarouba amara</i> Species of tree in the family Simaroubaceae

Simarouba amara is a species of tree in the family Simaroubaceae, found in the rainforests and savannahs of South and Central America and the Caribbean. It was first described by Aubl. in French Guiana in 1775 and is one of six species of Simarouba. The tree is evergreen, but produces a new set of leaves once a year. It requires relatively high levels of light to grow and grows rapidly in these conditions, but lives for a relatively short time. In Panama, it flowers during the dry season in February and March, whereas in Costa Rica, where there is no dry season it flowers later, between March and July. As the species is dioecious, the trees are either male or female and only produce male or female flowers. The small yellow flowers are thought to be pollinated by insects, the resulting fruits are dispersed by animals including monkeys, birds and fruit-eating bats and the seeds are also dispersed by leaf cutter ants.

<i>Platypodium elegans</i> Species of legume

Platypodium elegans, the graceful platypodium, is a large leguminous tree found in the Neotropics that forms part of the forest canopy. It was first described by Julius Rudolph Theodor Vogel in 1837 and is the type species of the genus. The tree has been known to grow up to 30 metres in height and have a trunk with a diameter up to 1 m at breast height. Its trunk has large holes in it, sometimes making it possible to see through the trunk. The holes provide a habitat for giant damselflies and other insects both when alive and once the tree has died and fallen over. It has compound leaves each of which is made up of 10–20 leaflets. Three new chemical compounds have been isolated from the leaves and they form part of the diet of several monkeys and the squirrel Sciurus ingrami. In Panama it flowers from April to June, the flowers contain only four ovules, but normally only one of these reaches maturity forming a winged seed pod around 10 cm long and weighing 2 g. During the dry season around a year after the flowers are fertilised, the seeds are dispersed by the wind and the tree loses it leaves. The seeds are eaten by agoutis and by bruchid beetle larvae. The majority of seedlings are killed by damping off fungi in the first few months of growth, with seedlings that grow nearer the parent trees being more likely to die. The seedlings are relatively unable to survive in deep shade compared to other species in the same habitat. Various epiphytes are known to grow on P. elegans with the cactus Epiphyllum phyllanthus being the most abundant in Panama. Despite having holes in its trunk which should encourage debris and seeds to collect, hemiepiphytes are relatively uncommon, meaning that animals are not attracted to it to feed and then defecate. It has no known uses in traditional medicine and although it can be used for timber, the wood is of poor quality.

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.
