A large tank-type epiphytic bromeliad with countless narrow, silvery gray leaves and a tall inflorescence with bright red bracts bearing long, ribbon-like tips.

A saxicolous, pulvinate species, often branched, with stout brown roots. Flowering height is 10 to 15 cm, with a caulescent stem longer than the rosette, up to 13 cm long. The rosette is up to 7 cm in diameter with 12 to 14 polystichous leaves, 3 to 7 cm long. Leaves are coriaceous to sub-succulent with an asymmetric keel, green-grey, covered with appressed cinereous scales. Named after Australian bromeliad enthusiast Len Colgan.
