A taxonomic reevaluation of two little-known Brimeura taxa, B. fontqueri (PAU) SPETA and B. duvigneaudii (L. LLORENS) ROSSELLÓ et al., has been made. Brimeura fontqueri, described from the Iberian peninsula, has been put into synonymy of B. amethystina (L.) SALISB., since it could not be distinguished on morphological, anatomical or cytogenetic grounds. Brimeura duvigneaudii, from the Balearic Islands, is closely related to B. amethystina and has 2n=28 chromosomes. It differs from the latter by its naked bulbs lacking dark cataphylls, and its narrower leaves and whitish corollas. Accessory chromosomes are reported for the first time in the genus. Karyological instability (with chromosome numbers ranging from 2n=28 to 42) is reported for a population of B. fastigiata (VIV.) CHOUARD. A key to the recognized taxa of Brimeura is provided.
