The Permian [(?) Late Cisuralian-Lopingian] outcrops of the La Golondrina Formation (Santa Cruz, Argentina), are known for their abundant and diverse fossil flora, including Gondwanan and Euramerican elements. However, of all the groups represented, fructifications have only been recognized for a few glossopterids and sphenophytes. This study reviews and describes 11 taxa from both specimens housed institutionally and recently collected, comprising a total of 14 fertile morphotaxa recognized in the La Golondrina Formation (excluding pteridophytes). In addition to their thorough systematic description, hindrances to identification related to the fragmentary nature and sparse occurrence of the fructifications are discussed. The La Golondrina Formation hosts the highest number of fructifications and greatest diversity amongst Permian basins in Argentina and elsewhere in South America, thus reaffirming its status as one of the most diverse floras of that time.
