. Our ferns in their haunts; a guide to all the native species. Ferns. THE SENSITIVE AND OSTRICH OTANISTS have always been divided in opinion as to whether the ostrich and sen- sitive ferns should be con- sidered members of the same family. They have an un- mistakable likeness and must be considered as cousins if not of nearer kinship. The princi- pal differences are that one has a running rootstock, scattered fronds and anastomosing veins, while the other has an upright rootstock, fronds in crowns and free veins. The first is the type of Onoclea, the second of Struthiopteris. Onoclea

Struthiopteris is also from the Greek and may be literally translated as ostrich fern. As modern botanists view them, there is but a single species of Onoclea in the world, and but two of Struthiopteris. The Sensitive Fern. The sensitive fern [Onoclea sensibilis) is one of our most abundant species. Wherever the soil is moist, in woodland, thicket and the open field, it is likely to occur,.
