Discussion
Type. Terrestrial, occasional in forest on crystalline laja on right bank of Rio Siapa 8 k m below Randal Gallineta (about 100 river k m from mouth), alt. 200-300 m, Amazonas, Venezuela, 20 Jul 1959, J. J. Wurdack & L. S. Adderley 43525 (holotype US).
The highly connate sepals of Bromelia tubulosa present the most extreme case of this character in the genus, so that nothing else is required to distinguish the species. However, it would seem most closely allied to B. fosteriana L. B. Smith of Suriname.
