Aniba alleniae is characterized by leaves obovate, oblong or broadly elliptic and abaxially tomentose, paniculate inflorescences at tip of branches below the terminal bud or along the new growth, sessile flowers with nine stamens in three whorls, whorls I and II with ventral-lateral locules, and the inner surface of the hypanthium and pistil glabrous. Ocotea palaciosii is also reported for the first time for the flora of Colombia.
