Abstract

This paper is a contribution to the study of little known Triassic fructifications from Argentina and elsewhere in Gondwana. Specimens are from the early Late Triassic Los Rastros Formation of the San Juan province. The studied taxa belong to the Pteridospermophyta, genera Umkomasia and Peltaspermum as well as Andersonia rastroensis new genus and species; Pinophyta, with the genus Telemachus of the Voltziaceae and the genus Matatiella of uncertain affinities. Comparisons with other Gondwana floras are given as well as discussions on certain taxonomical aspects.
