C. fertile.—Varieties of the frilled type have been found whichare partly fertile ; as seedlings they are fully equal to the barrenforms, but when they begin to bear spores, the frill is defective, thefrond apparently being incapable of bearing spores and completingthe frill. By virtue of this fertility, crosses have been effectedwith good PLATE XXXVI.
