I saw this species next to a road passing through pine forest (1800 m a.s.l.) on Langbian Mountain, Lam Dong Province, Central Highlands, Vietnam. As you can see in the habitat picture, the area was recently burned, but the plant survived due to the thick rhizome similar to that of Brainea insignis.
It can be distinguished from other Osmunda species because it has fertile pinnae at the lower part of its frond.
