During the Thai-Dutch botanical expedition to Thailand which lasted from November 1965 to February 1966, several interesting botanical discoveries were made. Among these we found Calocedrus macrolepis Kurz, a conifer which was formerly known only from southern China and Birma. Calocedrus macrolepis Kurz, J. Bot.
