#plant family
- Alismataceae — A family of monocotyledonous, herbaceous, perennial, aquatic or marsh plants adapted to life in wetlands and shallow waters. Plants in this family are characterized by laticiferous canals, highly polymorphic leaves arranged in a basal rosette, and 3-merous flowers with distinct green sepals and white or pink petals.
- Amaranthaceous — A dicotyledonous plant belonging to the Amaranthaceae family, characterized by small, often apetalous flowers grouped in dense spicate or paniculate inflorescences, adapted to various climates. As a plural adjective, it designates the family that includes species of ecological and economic value, such as amaranth, beets, and spinach.
- Amaranthus — The official botanical Latin taxonomic designation for a cosmopolitan genus of annual or perennial herbaceous plants in the Amaranthaceae family, commonly known as pigweed or amaranth. The genus comprises over 70 species recognized for their dense inflorescences, high nutritional value, and agricultural adaptability.
- Ampelidaceae — An historical or synonymous name from an old botanical classification system (Ampelidaceae) used to designate the family of dicotyledonous plants to which the grapevine belongs. In current modern taxonomy, this group of climbing shrubs and woody plants equipped with tendrils is officially classified under the name Vitaceae.
- Araucariaceous — Common name used to denote a member of the conifer family Araucariaceae or to describe elements characteristic of these relict Southern Hemisphere trees. As an adjective, the term qualifies the anatomical structures, leaves, or massive woody cones specific to this ancient plant lineage.
- Aristolochiaceous — A designation assigned to a plant belonging to the Aristolochiaceae family or, in the plural, to the family itself; a family of angiospermous dicotyledonous plants, generally perennial herbs or woody vines, distributed mainly in tropical and temperate regions. These plants feature entire, often cordate leaves and bisexual flowers with a bizarre tubular structure adapted for insect pollination, with many species containing dangerous toxic substances.
