Bubble Arch

The Purple Bubble tree (now driven to extinction) got pushed out of the Hugg Temperate forest due to all the broad leaf plents. To cope with this it evolved into the Bubble Arch. It can survive in poor soil and high winds. It developed an arch to keep it stable in the high winds. The bubble tree was already small but in fact it grew a bit to get as much sunlight it can from its trunk. It still has tiny leaves around the bubble seeds but they ate tiny. Any desperate herbivore will still have to deal with its exploding hydrogen seeds. It can kill its own nibbling herbivore prey. It uses the burnt carcass as fertilizer to help in grow thus enriching the poor rocky soil. It compliantly fire retardant now to deal with wildfires in the rocky cliffs. Many other other plants will catch on fire during th summer but the Bubble arch will stay virtually unaffected only loosing its seeds, which quickly grow back. This actually clears the annoying sticky balls in the area. Thus giving the other plants a chance to grow.
