Royal fern, Helecho real

Description:

Osmunda regalis is a deciduous fern, growing in woodland bogs and on the banks of streams. Osmunda regalis produces separate fertile and sterile fronds. The sterile fronds are 60–160 cm tall and 30–40 cm broad, bipinnate, with 7-9 pairs of pinnae up to 30 cm long, each pinna with 7-13 pairs of pinnules 2.5-6.5 cm long and 1-2 cm broad. The fertile fronds are erect and shorter, 20-50 cm tall, usually with 2-3 pairs of sterile pinnae at the base, and 7-14 pairs of fertile pinnae above bearing the densely-clustered sporangia. In many areas, O. regalis has become rare as a result of wetland drainage for agriculture.
