Coastal Bubbleweed

Splitting from its ancestor, the river bubbleweed, the coastal bubbleweed spread in all coasts in Glicker. Because its deeper, it doubled its size to reach the sun light. To not bend under its own weight, when it doesn't have any seeds, its stalk is bigger and stronger. Like its ancestor, it still has hydrogen-filled seed bubbles; these bubbles also keep the leaves upright and buoyant in the water. This works much like Earth's  kelp, except that when its bubbles fall off they actually float up and out of the water into the air before landing back into the water. They reproduce asexually with these bubble seed/spores.
