B. ‘Kew’ was simultaneously published in two senses by Preissel (1992, also 1993, 1994), once for a cultivar of B. sanguinea from Ecuador and the second for a cultivar of B. vulcanicola originating in Colombia, and both based on material acquired from the Royal Botanic Gardens Kew. The second instance does not meet the conditions for establishment of a cultivar name as there is no descriptive information that goes near to distinguishing a cultivar (only some information on habit and disease susceptibility: the plant had not flowered). We follow Kirchner-Abel et al. (2004: 65) in accepting the name for the B. sanguinea cultivar. It is unclear if it is the same as the “Kew form” of B. sanguinea described by Shaw (1998).
