Broad-Trunk Obsiditree

The broad-trunk obsiditree has arose from and replace the lacy-leaf obsiditree populations in the Dixon-Darwin Boreal, and risen to be one of the most dominant large flora in the montane regions of the Dixon-Darwin-Vivus Supercontinent. Thanks to lacking in large scale competition within the Dixon-Darwin Boreal, the lacy-leaf obsiditrees grew rapidly, taking advantage of the plentiful nutrients of the soil and attempting to outgrow competition from each other. As the millennia progressed, they became the keystone species of the region, making the vast majority of the trees-like flora within the region.

Their ancestors proto-branches have developed into true branches, which terminate in smaller, flat leaves. The branches are semi-flexible, allowing for them to shed snow, though their main defense against snow is their dark coloration. The dark pigmentation allows them to absorb heat from sunlight and discourage the formation of snowpiles and icicles. The darker coloration allows for them to maintain leaves throughout the year, as the more equatorial mountain ranges see little temperature variations, though they mostly grow their leaves in the wetter seasons of the years. They regularly shed their leaves, which provide an abundant source of nutrients in the soil that smaller flora take advantage of.

Like their ancestors they produces many granular airborne spores out of this chamber. The clouds are so abundant that they cause an orange haze to appear within the soil and snow. The spores combine in the air and settle on the soil or snow, and will wait for the soil to thaw or the snow to melt enough to implant. They spore will bud quickly, first sprouting meter deep roots before producing a 10 cm shrubling within a month. They have a slow growth rate later in life, due to the cooler temperatures of the regions they inhabit. They will take roughly 50 years to grow to full size, and will live for centuries, though as they lack internal ring a maximum ages is difficult to measure.
