Description
Family Bombacaceae
Trees
, usually large, often deciduous; trunks
sometimes spiny
, often buttressed
; bark
fibrous
, with mucilaginous
exudates
; indumentum usually stellate
or tufted
. Leaves alternate, spiral
; stipules inconspicuous, caducous
; petiole
pulvinate
; leaf blade
often palmately compound
(simple
and lobed
in Ochroma), margin
often entire. Inflorescences axillary
, 1(or 2) -flowered, rarely many-flowered. Flowers bisexual
, actinomorphic
, large and showy. Epicalyx
of 3 bracts, inconspicuous and caducous. Calyx shortly cylindrical, truncate
, or irregularly 3-5-lobed, sometimes splitting
. Petals 5, joined at base
with androecium and falling as one unit
, imbricate. Stamens usually very many (3-15 in Ceiba) ; filaments
usually united
in lower half into a filament tube around style, tube
sometimes lobed, with stamens in 5 groups with completely united filaments and sessile anthers
; anthers usually 1-celled, apparently 2-celled and non-septate in Ceiba, sometimes many anthers united into an apparent many-celled "super-anther"; pollen usually spheroidal
, ± smooth
, reticulate
; staminodes absent. Ovary superior, syncarpous
, carpels usually 5; ovules 2 to many per locule, axile
, anatropous
; style 5-lobed. Fruit a 5-valved capsule, or hard and indehiscent (e.g.
, Adansonia), many-seeded with seeds often embedded
in endocarp hairs
(kapok), less often fruit winged or juicy and few-seeded. Seeds sometimes winged
.
About 30 genera and ca.
250 species: found widely in tropics, especially tropical
America; three genera (two introduced
) and five species (two introduced) in China.
See the comments under the Malvaceae (p. 264) for the relationships
of the Bombacaceae.
Durio Adanson was at one time associated with this family
but has always been regarded as anomalous
and molecular data show it to be most closely related to the Helicteroideae (Sterculiaceae) but so distinct
morphologically that it might better be placed in its own family or subfamily
.[1]
Habitat
Biome: Terrestrial [2].
Ecology: A species occurring in lowland wet evergreen forest .[2].
