ABSTRACT

The vascular organization of the node in six genera has been investigated. The leaves are imparipinnately compound. These are alternate and exstipulate. A study of the nodal organisation of 15 members of the family Burseraceae revealed three nodal types: I. Trilacunar three traced, II. Pentalacunar five-traced and III. Multilacunar multi-traced. Trilacunar three-traced condition has been observed in 13 out of 15 species investigated. Whereas multilacunar multi- traced condition has been observed in species of Canarium. It is significant to note that Garuga pinnata in addition shows a trilacunar three-traced and pentalacunar five-traced condition. Trilacunar three-traced condition is considered to be basic for this family and it is believed that the pentalacunar five-traced condition and multilacunar-multitraced condition is a subsequent development through an elaboration of the lateral in the course of evolution

Key words : Burseraceae, Node, Nodal evolution
