AB -Taxonomic review of the genus Calocedrus in Vietnam accompanied with modern available data on distribution, ecology and habitat conditions of its two aboriginal species is presented. Detailed illustrated description of recently discovered species C. rupestris endemic to rocky limestone mountains of northern Vietnam is provided. This rare species differs from wide-spread C. macrolepis in obtuse to broadly-obtuse leaf apex; small, subsessile, 4-scaled, broadly-ovate seed cones 4-5(6) x 2.5-3(3.5) mm with very short stalk 0.5-1(1.5) mm long, having 6-8(12) obtuse scales, and fertile seed scales with incurved rounded apex having rough, more or less flat surface without any mucro. Trees of C. rupestris were found as a co-dominant in relictual coniferous forests on rocky hills and ridges composed of highly eroded limestone. Relictual primary, highly endangered woods with this rare tree, as well as their floristic complex represent a unique plant diversity center of global significance. Urgent and effective protection of these areas should be of highest priority for nature conservation activity.
