The traditional subfamilies Tillandsioideae and Bromelioideae are monophyletic, but Pitcair- nioideae are paraphyletic, requiring the description of four new subfamilies, recircumscription of Pit- cairnioideae and Navioideae, the sinking of Ayensua, and description of the new genus Sequencia. Brocchinioideae are basalmost, followed by Lindmanioideae, both restricted to the Guayana Shield. Next is an unresolved trichotomy involving Hechtioideae from Central America, Tillandsioideae, and the remaining bromeliads in subfamilies Navioideae, Pitcairnioideae, Puyoideae, and Bromelioideae.
