Synangium is a trilocular or three chambered, spore bearing structure in Psilotum.
It is considered as a fusion product of three sporangia.
Location: axils of foliar leaves on aerial shoot.
Synangium C.S:
It consists of 3 chambers or locules.
• Wall of synangium is 3-4 layered.
• Thick outer wall forms the epidermis.
• Inner wall separates the 3 locules.
• Each locule is filled with large no. of bean shaped spores (homosporous).
• Synangium splits along three longitudinal lines of dehiscence on the locules thereby releasing spores.
