Leaves generally in a basal rosette, spirally arranged to whorled, often unfolding crozier-like as in ferns, generally covered with gland-tipped, sensitive, sticky hairs (Dionaea, Drosera) or forming a trap (Dionaea); stipules mostly present. Flowers bisexual, regular, sepals 4-8, free or fused at the base, petals as sepals, stamens 4 or 5, occasionally 4 or 10-20. Ovary superior, the ovules numerous and with parietal placentation. Fruit a loculicidal capsule, mostly with numerous seeds.
Often grown in moss as insect-devouring botanical curiosities.
Leaves with sticky insect-catching glandular hairs, or leaves forming fly-catching traps.
