Brassavola flagellaris is a species of epiphytic orchid of the Cattleya alliance.

It grows wild in eastern Brazil (from Minas Gerais to Paraná),[1] where it fills the evening air with the citrus-like fragrance of its blossoms.

Brassavola flagellaris is a sympodial epiphyte (sometimes a lithophyte) with terete pseudobulbs, 6–30 cm long, each carrying a single elongated succulent leaf.

The erect or pendulous inflorescence carries one to several flowers bearing long and narrow light-green sepals which closely resemble the lateral petals.

The broad white lip closely encircles most of the light yellow-green column.
