Bot. Fennici 57: 367–375. The taxonomic position of Pseudolinosyris is revised. The genus is reduced to Gala- tella sect. Pseudolinosyris (Novopokr.) Sennikov comb. nova. It differs from the other sections by its shorter corolla lobes and a higher level of stem lignification. Two spe- cies are recognised in this section: G. grimmii (Regel & Schmalh.) Sennikov comb. nova, with three subspecies including G. grimmii subsp. microcephala (Novopokr.) Sennikov comb. nova and G. grimmii subsp. sintenisii (Bornm.) Sennikov comb. nova, and the newly added G. corymbulosa (Bornm.) Sennikov comb. nova. A further spe- cies is transferred from Crinitaria to Galatella, G. asperella (Rech. f. & Køie) Sen- nikov, comb. nova to form a monotypic section Galatella sect. Asperifoliae Sennikov, sect. nova. All the species and subspecies are redescribed and mapped, and their com- plete synonymy with typifications and a new identification key are provided.
