1) Ceiba speciosa (A.St.-Hil.) Ravenna
floss silk tree
Synonyms : Chorisia speciosa A.St.-Hil.
Ceiba speciosa, the floss silk tree (formerly Chorisia speciosa), is a species of deciduous tree that is native to the tropical and subtropical forests of South America. It has several local common names, such as palo borracho (in Spanish literally "drunken stick"), or árbol del puente, samu'ũ (in Guarani), or paineira (in Brazilian Portuguese). In Bolivia, it is called toborochi, meaning "tree of refuge" or "sheltering tree".[2] In the USA it often is called the silk floss tree. It belongs to the same family as the baobab and the kapok. Another tree of the same genus, Ceiba chodatii, is often referred to by the same common names.
Description
The natural habitat of the floss silk tree is in the northeast of Argentina, east of Bolivia, Paraguay, Uruguay, and southern Brazil. It is resistant to drought and moderate cold. It grows fast in spurts when water is abundant, and sometimes reaches more than 25 metres (82 ft) in height. Its trunk is bottle-shaped, generally bulging in its lower third, measuring up to 2 metres (7 ft) in girth. The trunk is studded with thick, sharp conical prickles that deter wild animals from climbing the trees. In younger trees, the trunk is green due to its high chlorophyll content, which makes it capable of performing photosynthesis when leaves are absent; with age it turns to gray.[3]
Leaves, stems, and flowers
The branches tend to be horizontal and also are covered with prickles. The leaves are composed of five to seven long leaflets. The flowers are creamy-whitish in the center and pink toward the tips of their five petals. They measure 10 to 15 centimetres (4 to 6 in) in diameter and their shape is superficially similar to hibiscus flowers. Their nectar is known to attract insect pollinators and hummingbirds.[4] C. speciosa flowers are in bloom between February and May (in its native Southern Hemisphere), but it may bloom at other times of the year, even as late as November in Florida. The flowers of the related C. chodatii are similar in form and size, but their color goes from creamy white centers to yellow tips.[3] As a deciduous tree, it is completely bare of leaves and flowers during the winter months, especially when growing outside of its native South American habitat.

2) Ceiba insignis (Kunth) P.E.Gibbs & Semir
white floss-silk tree
설명1)
Ceiba insignis (syn. Chorisia insignis), the white floss-silk tree, is a species of flowering plant in the family Malvaceae, native to dry tropical forests of southern Ecuador and northern Peru.[1][2] It has found use as a street tree in scattered cities around the world.[3]

설명2)
Characteristics: Ceiba insignis is a distinctive deciduous tree with a swollen, thorny trunk and spreading branches (1). It normally grows to about 30 feet in height with an equal width, although older trees can grow taller (1,2). Its serrated leaves emerge in late April to early May and are palmately compound with 5-7 oblong leaflets per leaf, each measuring 2 to 3 inches long (3). During the fall and winter, the tree produces beautiful creamy-white or pale yellow flowers, which may be suffused or streaked with pink (3). The flowers, measuring 5 inches in diameter, have 5 petals, 3-5 inches long and one inch wide, which are pubescent on the outside and smooth inside (3). Flowers are perfect and produce joined filaments that extend outwards about 3 inches, enclosing the longer stigma (2). In its native range, flowers open in the evening and are pollinated by nocturnal pollinators, although the exact type of pollinator is unknown (3). Flowers are followed by smooth, green, pear-shaped fruits, known as capsules, which measure 4-5 inches in length and 2-3 inches in diameter (4). As the fruits dry, they split open, releasing seeds cradled in dense masses of white, silky hairs, which give the plant its name (5). When young, the trunk and branches are covered with green bark that is capable of photosynthesis, but becomes gray and fissured with age. The bark is covered with sharp, conical projections, often referred to as prickles. Ceiba insignis differs from the more common Ceiba speciosa in having creamy-white flowers and a stouter appearance due to its shorter stature and more swollen trunk that can reach up to 6.5 feet in diameter. (1,6,7).

3) Ceiba chodatii (Hassl.) Ravenna
floss silk tree,
Ceiba chodatii, the floss silk tree, is a species of deciduous tree native to the tropical and subtropical forests of South America. It has a bottle-shaped swollen trunk in which water is stored for the dry season and is known locally as palo borracho.
Description
Flowers of Ceiba chodatii
Ceiba chodatii is a medium-sized deciduous tree with a tall, stout, bare trunk. It grows to about 12 metres (39 ft) tall, has a number of thick branches at the top of the swollen trunk and has a rounded crown. The bark is smooth with vertical ridges and horizontal wrinkles. It contains chlorophyll and is green when young and able to photosynthesize, but turns grey with age. It is covered with thick, woody conical spines. The alternate leaves are palmate with five lobes and serrated edges. The flowers are large, solitary and creamy white with a few purple flecks. They are up to 15 centimetres (5.9 in) long with yellow-green calyces and funnel-shaped corollas with five fleshy, hairy petals joined at the base. The fruit is a large, oblong green capsule. When ripe it splits open to reveal black seeds surrounded by a mass of white fibres resembling cotton.[2]
