Para Bolagae

The para bolagae replaced its ancestor the bolagae alongside the multitube. The para bolagae may look different from its ancestor but is in fact rather similar. The tube still produce spores but the spores are released directly inside the onion shaped trunk. The trunk is attached to the ground but only a thin membrane keeps it from being torn away from the ground. Over time the oxygen made from photosynthesis together with currents in the river will tear the para bolagae from the ground and then the spores will be released from inside the trunk. The tube now grows from the roof of the trunk instead of the bottom. Apart from these differences the para bolagae is exactly like its ancestor.
