Aquilinan, an acidic polysaccharide from Pteridium aquilinum
Phytochemistry, 1976Abstract A water-soluble, acidic polysaccharide, aquilinan, was isolated from storage rhizomes and young fronds of bracken and shown to be homogeneous. The polysaccharide contained galactose, xylose, fucose and arabinose residues together with chains of repeating α(1-2′)glucuronosylmannose units.

The cytoplasmic vesicles of the female reproductive cells of Pteridium aquilinum
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1969Cytoplasmic vesicles appear in conspicuous numbers during oogenesis in the fern Pteridium aquilinum. Two classes of vesicles are recognized: Golgi vesicles, of the order of 0.1 μ in diameter, and larger vesicles, of the order of 0.75 μ in diameter, apparently not derived from the Golgi apparatus.

Adaptation of Pteridium aquilinum (L.) Kuhn in Siberia
Contemporary Problems of Ecology, 2010The study has revealed some specific ecological and biological characteristics of bracken that facilitate not only its adaptation to temperate climate, but also dominance in the herbaceous cover, and advancement into new areas within its range. It has been shown that the ecological optimum of bracken is oceanic climate and in Siberia the fern occurs at
