Smith & Downs (1977) cited Vriesea macropetala hort. (Rev. Hort. 69: 336. 1897) as synonym of Tillandsia viridiflora. However, this name is only mentioned in a publication of the Société National d́Horticulture de France without any description or mention of a basionym. Probably, Smith & Downs (1977) supposed that the name could be a transfer from Tillandsia macropetala Wawra, because of the same epithet, although we think that there is no clear evidence and it might be a nomen nudum. —SeeKromer et al. 2012
