Abstract. GYMNOSPERMOUS WOODS FROM SOLCA FORMATION (LOWER PERMIAN), LA RIOJA PROVINCE, ARGENTINA. For the first time gymnospermous woods from the Solca Formation (Lower Permian) from the Olta and Parque Guasamayo localities are described. The Conifers Agathoxylon kumarpurensis (Bajpai and Singh) Crisafulli and Herbst nov.comb. and Agathoxylon ningahense (Maheshwari) Crisafulli and Herbst nov. comb. have been transferred from Araucarioxylon; also Podocarpoxylon indicum (Bhardwaj) Bose and Maheshwari, have been transferred from Araucarioxylon; also Podocarpoxylon indicum (Bhardwaj) Bose and Maheshwari, Crisafulli and Herbst nov.comb. and Agathoxylon ningahense (Maheshwari) Crisafulli and Herbst nov. comb. have been transferred from Araucarioxylon; also Podocarpoxylon indicum (Bhardwaj) Bose and Maheshwari, have been transferred from Araucarioxylon; also Podocarpoxylon indicum (Bhardwaj) Bose and Maheshwari, For the first time gymnospermous woods from the Solca Formation (Lower Permian) from the Olta and Parque Guasamayo localities are described.

Chapmanoxylon preserves homogeneous pith, primary and secondary xylem; the other taxa only have secondary xylem all of which present interruptions in the growth and distorsion in transverse sections. These picnoxilic woods based on tracheidal characters are clasified in three groups: with araucarioid pits, with araucarioid-abietinoid pits and finally with araucarioid, mixed and tending to abietinoid pits. have secondary xylem all of which present interruptions in the growth and distorsion in transverse sections.

Chapmanoxylon jamuriense, Agathoxylon kumarpurensis and Agathoxylon ningahense were found in the Raniganj Formation in India. The latter species was also recorded in the Mount Glossopteris (Antarctica) and Melo (Uruguay) Formations while Agathoxylon kumarpurensis together with Podocarpoxylon indicum were found in Springfontain (South Africa) , all from the Permian. Genus Podocarpoxylon is also present in the Triassic El Tranquilo Group (Patagonia) and Jurassic of Rajmahal (India).
