"Drosera adelae" is a tropical perennial plant that produces long, sword-shaped leaves in a basal rosette. The leaves, like most other "Drosera" species, are covered with sticky, stalked tentacles that secrete the prey-capturing glue. Tentacle movement in this species, unlike other "Drosera", is minimal and slow to the point of being barely noticeable. The leaves are narrowly lanceolate and are typically long and 7–10 mm wide. The lower surface of the leaves are glabrous and petioles are either very short or absent. Inflorescences are one-sided raceme and up to long, bearing many red, reddish orange, or cream coloured flowers from June to November. The five petals produce a perfect pentagon shape.
