Temperature ranges for seed germination were determined for palm species Acoelorraphe wrightii (Griseb. & H. Wendl.) H. Wendle ex. Becc., Coccothrinax argentata (Jacq) L. H. Bailey, Sabal etonia Swingle ex Nash, and Thrinax morrisii H. Wendl. Total germination was highest with fewest days to 50% of final germination at 35°C Temperatures 5° to 10° above or below 35° frequently caused delayed, irregular, and reduced total germination. Temperatures exceeding 10° from 35° generally were inadequate for germination.
