The vascular cambium ofAlbizzia, Tectona, Terminalia, Calophyllum, MangiferaandMorindawas non‐storied while that ofDalbergiawas semi‐storied. The ray initials were uniseriate inTerminaliaandCalophyllum, both uniseriate and biseriate inAlbizzia, Dalbergia, MangiferaandMorindaand were also multiseriate inTectona. They were homogeneous inAlbizziaand heterogeneous in the other species. The radial walls of cambial cells were always beaded, although beads were more prominent and closer to one another during periods of cambial dormancy than during activity. The fusiform initials were comparatively less vacuolated during dormancy/ least activity. When active, the fusiform and ray initials of all species, exceptCalophyllum, also showed multinucleate condition (2–10 depending on species). The proportion of ray initials to fusiform initials was almost constant throughout the year in all sp
