This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1911 edition. Excerpt: ...peculiarity, the silvery spleenwort and at times the ostrich-fern. But the silvery spleenwort is always hairy, and the stem of the ostrich-fern is much more deeply grooved in front and flattened on the sides, and the rachis is narrowly winged on each side, its pinnae are merely pinnatifid with entire lobes, and the lower pinnae are much reduced.

They germinate very readily, and are, perhaps, the best for experiments at home. To obtain them we need only pick heavily-fruited pinnae and let them dry out in a paper box or bag for a dav or two until the spores are discharged. The prothalli and young plants in all stages are readily found on moist earth wherever the lady-fern is at all abundant. In spite of its being a favorite of the poets, it must be confessed that the lady-fern is not nearly as attractive as many of our other ferns. There is a certain coarseness about it that detracts from its appearance, and makes it inferior to the spinulose wood-fern, with which beginners are apt to confound it.
