摘要：
Passovia (Loranthaceae) is a Neotropical genus of mistletoes characterized by having inflorescences with triads and flowers with laterally excavated filaments and basifixed anthers. During the revision of Loranthaceae for the Flora do Brasil 2020 project, a single collection of an undescribed species of Passovia was found at the Museum Paraense Emilio Goeldi herbarium (MG). We described and illustrated this specimen as Passovia bracteata, a new species endemic from the Brazilian Amazon Forest. This new species is characterized by its terete stems, ovate leaves, racemose inflorescences (compound at the base), and pedunculate triads with a long-foliaceous bract subtending the median flower of the triad and/or the whole triad.
