Adiantum raddianum 'Lambertianum'

Large fern with open fronds, the widespread elongated segments characteristically twisted and contorted with the edges toothed and variously lobed; the smaller fertile segments generally with one sorus per lobe. The yellowish veins in the segments give the plant a variegated appearance. Possibly originated as a form of 'Gracillimum' with more deeply lobed segments.
