Pseudobulbs of a few orchid species in genera Pleione and Porpax got a unique sheath covering. As the bulb matures, the sheath partially disintegrates to form a fine fibrous radiating set of veins either forming a net-like pattern or longitudinally converging. This characteristic helps in identifying the species while they are not in bloom or leaf-less.
