Extrafloral nectories (other than the glands that we have been discussing about so far) are common in members of Combretaceae. But they usually occur in the axils of nerves on the lower surface of the leaf. You may examine the undersurface of badam (Terminalia catappa) leaf for e.g., to see the hairy structures (called 'domatia'). However, the spots pointed by Surajit ji do not seem to be the extrafloral nectories. They may be (bacterial?) infections?
Thanks Surajit ji, for the clear pictures of glands. They seem to vary in number and position in this species too.
