Anthurium jenmanii, photographed by Phil Nelson.

Belongs within: Alismatanae.
Contains: Orontioideae, Lemnaceae, Aroideae, Monsteroideae.

The Araceae are a family of flowering plants in which most species have the flowers reduced and clustered onto a compact spike that is in turn subtended by a large, often colourful bract.

Characters (from the Angiosperm Phylogeny Website): Cyanogenic glucoside triglochinin, flavone C-glycosides present; dimorphic root hypodermis present; sieve tube plastids also with starch; pseudopetiole bundles scattered; stomata unorientated, also anomo- and tetracytic; leaves usually with pseudopetiole, lamina and (pseudo)midrib, tertiary venation cross to reticulate, base with lateral (occasionally auriculate) flanges; inflorescence densely spicate [spadix], unbranched, inflorescence bract well developed, ± coloured, ± surrounding spadix [spathe]; flowers sessile, floral bracts absent; flowers 2-3-merous, in latter case median member of outer whorl of tepals adaxial, tepals ± hooded, with single trace, free (sometimes connate); anthers extrorse; pollen with ektexine present; septal nectaries absent; carpels (basally) ascidiate, fusion usually congenital, loculus usually with secretion, style at most short, stigma also wet; ovules ± unvascularized; fruit a berry; testa multiplicative, ≥5 cells across, often parenchymatous, or with exotesta and/or endotesta and mesotesta lignified, tegmen collapsed; x = 16; cotyledon not photosynthetic.
