The family '''Acanthaceae''' (or '''Acanthus family''') is a taxon of [[dicotyledon]]ous [[flowering plant]]s containing almost 250 genera and about 2500 species.
Most are [[tropical]] [[herb]]s, shrubs, or twining vines; some are [[epiphytes]]. Only a few species are distributed in [[temperate]] regions. The four main centres of distribution are [[Indonesia]] and [[Malaysia]], [[Africa]], [[Brasil]] and [[Central America]]. The representatives of the family can be found in nearly every [[Habitat (ecology)|habitat]], including dense or open [[forests]], in [[Scrubland|scrublands]], on wet fields and valleys, at the sea coast and in marine areas, and in [[swamps]] and as an element of [[mangrove]] woods.

Plants in this family have simple, opposite, decussate [[leaf|leaves]] with entire (or sometimes toothed, lobed, or spiny) margins, and without stipules. The leaves may contain cystoliths, or calcium carbonate concretions, seen as streaks on the surface. The [[flower]]s are perfect, zygomorphic to nearly actinomorphic, these arranged in an [[inflorescence]] that is either a [[raceme|spike]], [[raceme]], or cyme. Typically there is a colorful bract subtending each flower; in some species the bract is large and showy. The calyx is usually 4-5 lobed; the corolla tubular, 2-lipped or 5-lobed; [[stamen]]s either 2 or 4 arranged in pairs and inserted on the corolla; and the [[carpel|ovary]] superior, 2-carpellate, with axile placentation. The [[fruit]] is a two-celled [[capsule (fruit)|capsule]], dehiscing somewhat explosively. In most species, the [[seed]]s are attached to a small, hooked stalk (a modified ''funiculus'' called a ''jaculator'') that ejects them from the capsule.
A species well-known to temperate gardeners is ''[[Acanthus (genus)|Acanthus]] mollis'' or Bear's breeches, a herbaceous perennial plant with big leaves and flower spikes up to 2 m tall. Tropical genera familiar to gardeners include ''[[Thunbergia]]'' and ''[[Justicia]]''.
''[[Avicennia]]'', usually placed in [[Verbenaceae]] or in its own family, [[Avicenniaceae]], is included in Acanthaceae by the [[Angiosperm Phylogeny Group]] on the basis of molecular phylogenetic studies that show it to be associated with this family.

The family '''Acanthaceae''' (or '''Acanthus family''') is a taxon of [[dicotyledon]]ous [[flowering plant]]s containing almost 250 genera and about 2500 species.
Most are [[tropical]] [[herb]]s, shrubs, or twining vines; some are [[epiphytes]]. Only a few species are distributed in [[temperate]] regions. The four main centres of distribution are [[Indonesia]] and [[Malaysia]], [[Africa]], [[Brasil]] and [[Central America]].
