Polylepis is a genus comprising 28 recognised shrub and tree species, that are endemic to the mid- and high-elevation regions of the tropical Andes. This group is unique in the rose family in that it is predominantly wind-pollinated. They are usually gnarled in shape, but in certain areas some trees are 15–20 m tall and have 2 m-thick trunks. The foliage is evergreen, with dense small leaves, and often having large amounts of dead twigs hanging down from the underside of the canopy. The name Polylepis is, in fact, derived from the Greek words poly (many) plus letis (layers), referring to the shredding, multi-layered bark that is common to all species of the genus. The bark is thick and rough and densely layered for protection against low temperatures. Some species of Polylepis form woodlands growing well above normal tree line within grass and scrub associations at elevations over 5000 m; which makes Polylepis appear to be the highest naturally occurring arboraceous angiosperm genus in the world.

This species, along with B. mindorensis, produces the unusual, conspicuous, persistent bracts on the inflorescences. However, it sharply distinct from the latter due to its ovate to lanceolate bracts, which are hyaline, membranaceous, glabrous or with very sparse sessile glands where the latter have widely to depressed ovate bracts that are coriaceous, densely clothed with sessile glands. Additionally, B. tenuibracteata differs by the congested rhizomes with internodes only to 3 mm long; with shorter petioles ; velvety upper leaf surface; shorter inflorescence ; and fewer stamens (40–50); whereas B. mindorensis have 20 mm long rhizome internodes, petioles 10–25 cm long, glossy upper leaf surface, inflorescence over 35 cm long, and up to ca. 70 stamens
