Well, we know from observation what trees look like that are subjected to harsh high winds that blow constantly:
If trees in this otherworld evolved in a windy atmosphere, then they would probably end up bent over like these venerable Ancients.
But, let's think a little out of the pine box:
Suppose that the trees in this world evolved within a normal atmosphere: occasional storms, occasional seasonal high winds, plenty of calm airs as well. Now let's suppose that in this region, high winds and storms and fires and so forth occur usually in the summer.
One strategy is to blossom and set seeds before the summer storms and fires rage. Plants that do this will be burnt by fire and their ashes and twigs will be swept away. This will leave the seeds already in the ground a happy place to spring up again next year and start all over again.
This is not a good strategy for trees, who live for many years. So I introduce the scarwood tree. Its wood is dense and sturdy (like a bristlecone's) and its bark grows thick and can slough off in layers when fire touches it, thus protecting the bark layers and wood underneath.
But the scarwood, rather than dropping seeds in the late spring, takes advantage of the high winds of summer by sending up long thin tendrils into the windy airs above the woodlands. These filaments grow up and out of the trees' flowers.
As the winds pick up, the filaments grow, and at the end of each is a kind of wing-like leaf, much like that of a maple's samara:
But the scarwood's seed has broad thin wings and flies like a kite high on the breeze! As the winds strengthen and the fires approach, the now matured seeds are released at the base of the filament. And they fly away on the wind to a safe distance from the fires, where eventually they'll land and sprout a new generation of scarwood.
That is to say: kite flower trees!
