Billbergia nobilis in Taxon 34: 294. 1985


Coincidentally with the preparation of the Bull paper above, a new name in the Bromeliaceae was uncovered during some literature research at Kew and Oxford by Dave Philcox. His note follows:

Billbergia nobilis was validly described by William Bull in his List of New plants in 1901, a horticultural catalogue. No holotype of this name exists but I consider a drawing published three years later by Bull in his catalogue of Plants to be an acceptable neotype. Both from his description and illustration I consider this plant to be synonymous with B. porteana Brong.
