Is photosynthesis especially vigorous on your planet?
For your planet to maintain its high oxygen/low co2 with enough fires to influence evolution it would have had to be going on for whole epochs, wouldn't it? Wouldn't the CO2 rise and the O2 drop eventually? Or am I missing something?
Anyway don't write off a cotton analog. Fluffy seed are for wind dispersal - they could be fire retardent and use the updrafts from the fires for seed dispersal. As for linen analogs - would bast fibre really be a problem? They are inside the plant after all. If the outer bark is fire resistant it should be okay. Even if not a flax analog what about bark cloths such as http://en.wikipedia.org/wiki/Cedar_bark_textile or http://en.wikipedia.org/wiki/Tapa_cloth ?
